This PR is LGTM, but do we need to additionally consider the following cases, where the print-width is exceeded and there are multiple keys? This is not possible in the current ECMAScript / HTML standard, but it may be something to consider for the future.

Prettier pr-16349
Playground link

--parser babel

Input:

import something from "./some-very-very-very-very-very-very-very-very-long-path.json" with {
  type: "json", otherKey1: "foo", otherKey2: "foo"
};

Output:

import something from "./some-very-very-very-very-very-very-very-very-long-path.json" with { type: "json", otherKey1: "foo", otherKey2: "foo" };

I agree, we may want check attributes length in future.

I'm not sure if the spec allow line break before with. For really long declarations, we may want format like this?

import something
  from "./some-very-very-very-very-very-very-very-very-long-path.json" 
  with {
    type: "json", otherKey1: "foo", otherKey2: "foo"
  };

TS throws in playground

But Babel allows

##### [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### [v3.2.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#324)

[diff](prettier/prettier@3.2.3...3.2.4)

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json

// Prettier 3.2.2

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)

```

<!-- prettier-ignore -->

```ts

##### Fix parser inference ([#15927](prettier/prettier#15927) by [@fisker](https://github.com/fisker))

##### [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

```jsx
<style {...spread}>{`.{}`}</style>
```

##### Fix formatting error on optional call expression and member chain ([#15920](prettier/prettier#15920) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

##### [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

##### [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

  template: `<div>...</div>`,

// Prettier 3.2.5

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}

##### [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

```jsx

##### [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

##### [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})

```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input

	    : gggggggggggggggg;

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,

: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;

a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

<!-- prettier-ignore -->

})
export class AppComponent {}

// Prettier 3.2.4

export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})

```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx

// Prettier 3.1.1
const {

```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx

```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx

```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

})
export class AppComponent {}

// Prettier 3.2.4

export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.5
@component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;
    }
  `,
})
export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

```
```


## [v3.2.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#324)

[diff](prettier/prettier@3.2.3...3.2.4)

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "json" }
```


## [v3.2.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#323)

[diff](prettier/prettier@3.2.2...3.2.3)

##### Throw errors for invalid code ([#15881](prettier/prettier#15881) by [@fisker](https://github.com/fisker), [@Josh-Cena](https://github.com/Josh-Cena), [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```ts

// Prettier 3.2.2
1++;

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)

##### Fix parser inference ([#15927](prettier/prettier#15927) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```console
// Prettier 3.2.2

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

```jsx
<style {...spread}>{`.{}`}</style>
```

##### Fix formatting error on optional call expression and member chain ([#15920](prettier/prettier#15920) by [@sosukesuzuki](https://github.com/sosukesuzuki))

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

## [v3.0.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#303)

[diff](prettier/prettier@3.0.2...3.0.3)

##### Add `preferUnplugged: true` to `package.json` ([#15169](prettier/prettier#15169) by [@fisker](https://github.com/fisker) and [@so1ve](https://github.com/so1ve))

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE
  ? path.join(__dirname, "../standalone.js")
  : path.join(__dirname, ".."));

// Prettier 3.0.3
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);
```

##### Do not print trailing commas in arrow function type parameter lists in `ts` code blocks ([#15286](prettier/prettier#15286) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

````md
<!-- Input -->

[diff](prettier/prettier@3.0.0...3.0.1)

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// <|> is the cursor position

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.5
@component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;
    }
  `,
})
export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

<!-- prettier-ignore -->

```
```


## [v3.2.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#324)

[diff](prettier/prettier@3.2.3...3.2.4)

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "json" }
```


## [v3.2.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#323)

[diff](prettier/prettier@3.2.2...3.2.3)

##### Throw errors for invalid code ([#15881](prettier/prettier#15881) by [@fisker](https://github.com/fisker), [@Josh-Cena](https://github.com/Josh-Cena), [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```ts
// Input
1++;

// Prettier 3.2.2
1++;

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)
> 1 | 1++;
    | ^
```

<!-- prettier-ignore -->

```ts
// Input
try {} catch (error = 1){}

// Prettier 3.2.2
try {
} catch (error) {}

// Prettier 3.2.3
SyntaxError: Catch clause variable cannot have an initializer. (1:23)
> 1 | try {} catch (error = 1){}
    |                       ^
```

##### Fix parser inference ([#15927](prettier/prettier#15927) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```console
// Prettier 3.2.2
prettier --file-info tsconfig.json

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

```jsx
<style {...spread}>{`.{}`}</style>
```

##### Fix formatting error on optional call expression and member chain ([#15920](prettier/prettier#15920) by [@sosukesuzuki](https://github.com/sosukesuzuki))

// Prettier 3.2.1
TypeError: Cannot read properties of undefined (reading 'type')

// Prettier 3.2.2
a(() => {}, c?.d());
```

[diff](prettier/prettier@3.2.0...3.2.1)

##### Fix formatting error on member chain ([#15915](prettier/prettier#15915) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

🔗 [Release Notes](https://prettier.io/blog/2024/01/13/3.2.0.html)


## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

[diff](prettier/prettier@3.0.2...3.0.3)

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(

    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE

// Prettier 3.0.3
const plugin = require(

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input

```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

@component({
  template: `<div>...</div>`,
  styles: `
    h1 {

})
export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

// Prettier 3.0.3
const plugin = require(

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

<!-- prettier-ignore -->

```ts

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

    h1 {

export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)

```

<!-- prettier-ignore -->

```ts

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx

// Prettier 3.0.3
const plugin = require(

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};

import bar from "bar";

// Prettier 3.1.1

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

<!-- prettier-ignore -->

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input

	    ? fffffffffffffff
	    : gggggggggggggggg;

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

// Prettier 3.1.1
const {

```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts

class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input

@component({

})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input

class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(

// Prettier 3.0.3
const plugin = require(

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

```

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

[diff](prettier/prettier@3.0.2...3.0.3)

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2

// Prettier 3.0.3
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")

[diff](prettier/prettier@3.0.0...3.0.1)

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(

    : path.join(__dirname, "..")
);

// Prettier 3.0.2

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// <|> is the cursor position

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})

```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

// Prettier 3.1.1
const {

```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx

```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

```js
// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;

a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

// Prettier 3.2.5
@component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;

})
export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json

## [v3.2.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#323)

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)

```

<!-- prettier-ignore -->

```ts

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

// Prettier 3.0.3
const plugin = require(

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)

```

<!-- prettier-ignore -->

```ts

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

// Prettier 3.0.3
const plugin = require(

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

<!-- prettier-ignore -->

```ts

class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)

```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json

##### Fix parser inference ([#15927](prettier/prettier#15927) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0

import bar from "bar";

// Prettier 3.1.1

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(

    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE
  ? path.join(__dirname, "../standalone.js")
  : path.join(__dirname, ".."));

// Prettier 3.0.3
const plugin = require(

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

<!-- prettier-ignore -->

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff

```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

// Prettier 3.1.0

import /* comment */ "bar";

import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};

## [v3.0.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#303)

[diff](prettier/prettier@3.0.2...3.0.3)

##### Add `preferUnplugged: true` to `package.json` ([#15169](prettier/prettier#15169) by [@fisker](https://github.com/fisker) and [@so1ve](https://github.com/so1ve))

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts

class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4

// Prettier 3.2.5
@component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;

})
export class AppComponent {}

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

## [v3.2.4](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#324)

[diff](prettier/prettier@3.2.3...3.2.4)

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

```jsx
// Input
prettier --file-info .eslintrc.json

// Prettier 3.2.4
prettier --file-info .eslintrc.json

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff

aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts

class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts

@component({

})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```


## [v3.1.0](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#310)

## [v3.0.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#303)

[diff](prettier/prettier@3.0.2...3.0.3)

##### Add `preferUnplugged: true` to `package.json` ([#15169](prettier/prettier#15169) by [@fisker](https://github.com/fisker) and [@so1ve](https://github.com/so1ve))

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE
  ? path.join(__dirname, "../standalone.js")
  : path.join(__dirname, ".."));

// Prettier 3.0.3
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);
```

##### Do not print trailing commas in arrow function type parameter lists in `ts` code blocks ([#15286](prettier/prettier#15286) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

````md
<!-- Input -->
```ts
const foo = <T>() => {}
```

<!-- Prettier 3.0.2 -->
```ts
const foo = <T,>() => {}
```

<!-- Prettier 3.0.3 -->
```ts
const foo = <T>() => {}
```
````

##### Support TypeScript 5.2 `using` / `await using` declaration ([#15321](prettier/prettier#15321) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Support for the upcoming Explicit Resource Management feature in ECMAScript. [`using` / `await using` declaration](https://devblogs.microsoft.com/typescript/announcing-typescript-5-2/#using-declarations-and-explicit-resource-management)

<!-- prettier-ignore -->

```tsx
{
   using foo = new Foo();
   await using bar = new Bar();

[diff](prettier/prettier@3.0.0...3.0.1)

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// <|> is the cursor position

/* Input */
// All messages are represented in JSON.
// So, the prettier.py controls a subprocess which spawns "node {this_file}".

```

##### Add typing to support `readonly` array properties of AST Node ([#15127](prettier/prettier#15127) by [@auvred](https://github.com/auvred))

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

## [v3.2.5](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#325)

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,

  styles: `
    h1 {
      color: blue;

```

##### Unexpected embedded formatting for Angular template ([#15969](prettier/prettier#15969) by [@JounQin](https://github.com/JounQin))

Computed template should not be considered as Angular component template

<!-- prettier-ignore -->

```ts
// Input
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

```
```

##### Fix incorrect parser inference ([#15947](prettier/prettier#15947) by [@fisker](https://github.com/fisker))

Files like `.eslintrc.json` were incorrectly formatted as JSONC files.

<!-- prettier-ignore -->

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

[diff](prettier/prettier@3.0.2...3.0.3)

##### Add `preferUnplugged: true` to `package.json` ([#15169](prettier/prettier#15169) by [@fisker](https://github.com/fisker) and [@so1ve](https://github.com/so1ve))

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE
  ? path.join(__dirname, "../standalone.js")
  : path.join(__dirname, ".."));

// Prettier 3.0.3
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);
```

[diff](prettier/prettier@3.0.0...3.0.1)

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js

## [v3.3.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)

[diff](prettier/prettier@3.3.2...3.3.3)

##### Add parentheses for nullish coalescing in ternary ([#16391](prettier/prettier#16391) by [@cdignam-segment](https://github.com/cdignam-segment))

This change adds clarity to operator precedence.

<!-- prettier-ignore -->

a ? b : foo ?? bar;

// Prettier 3.3.2

a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);
```

##### Add parentheses for decorator expressions ([#16458](prettier/prettier#16458) by [@y-schneider](https://github.com/y-schneider))

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

<!-- prettier-ignore -->

```ts
// Input
@(foo`tagged template`)
class X {}

// Prettier 3.3.2
@foo`tagged template`
class X {}

// Prettier 3.3.3
@(foo`tagged template`)
class X {}
```

##### Support `@let` declaration syntax ([#16474](prettier/prettier#16474) by [@sosukesuzuki](https://github.com/sosukesuzuki))

Adds support for Angular v18 `@let` declaration syntax.

Please see the following code example. The `@let` declaration allows you to define local variables within the template:

<!-- prettier-ignore -->

```html
@let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}
```

For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

[diff](prettier/prettier@3.2.4...3.2.5)

##### Support Angular inline styles as single template literal ([#15968](prettier/prettier#15968) by [@sosukesuzuki](https://github.com/sosukesuzuki))

[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.

<!-- prettier-ignore -->

```ts
// Input
@component({
  template: `<div>...</div>`,

export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}
```

##### Use `"json"` parser for `tsconfig.json` by default ([#16012](prettier/prettier#16012) by [@sosukesuzuki](https://github.com/sosukesuzuki))

In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), we introduced `"jsonc"` parser which adds trialing comma **by default**.

When adding a new parser we also define how it will be used based on the [`linguist-languages`](https://www.npmjs.com/package/linguist-languages) data.

`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_json-with-comments) syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing `.json` file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the `"jsonc"` parser for your `tsconfig.json` files, add the following to your `.pretterrc` file

```json
{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}
```

## [v3.2.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#323)

[diff](prettier/prettier@3.2.2...3.2.3)

##### Throw errors for invalid code ([#15881](prettier/prettier#15881) by [@fisker](https://github.com/fisker), [@Josh-Cena](https://github.com/Josh-Cena), [@auvred](https://github.com/auvred))

##### Fix parser inference ([#15927](prettier/prettier#15927) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```console
// Prettier 3.2.2

## [v3.2.2](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#322)

[diff](prettier/prettier@3.2.1...3.2.2)

##### Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute ([#15896](prettier/prettier#15896) by [@eelco](https://github.com/eelco))

For example this code would crash before:

<!-- prettier-ignore -->

```jsx
<style {...spread}>{`.{}`}</style>
```

##### Fix formatting error on optional call expression and member chain ([#15920](prettier/prettier#15920) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```jsx
// Input

TypeError: Cannot read properties of undefined (reading 'type')

// Prettier 3.2.2
a(() => {}, c?.d());
```

[diff](prettier/prettier@3.1.1...3.2.0)

🔗 [Release Notes](https://prettier.io/blog/2024/01/13/3.2.0.html)


## [v3.1.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#311)

[diff](prettier/prettier@3.1.0...3.1.1)

##### Fix config file search ([#15363](prettier/prettier#15363) by [@fisker](https://github.com/fisker))

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

```text
├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc
```

```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc
```

##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](prettier/prettier#15533) by [@sanmai-NL](https://github.com/sanmai-NL))

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use `--no-error-on-unmatched-pattern` to simply skip symbolic links.

##### Consistently use tabs in ternaries when `useTabs` is `true` ([#15662](prettier/prettier#15662) by [@auvred](https://github.com/auvred))

<!-- prettier-ignore -->

```jsx
// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;
```

##### Improve config file search ([#15663](prettier/prettier#15663) by [@fisker](https://github.com/fisker))

The Prettier config file search performance has been improved by more effective cache strategy.

##### Fix unstable and ugly formatting for comments in destructuring patterns ([#15708](prettier/prettier#15708) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

```tsx
// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;
```

##### Support "Import Attributes" ([#15718](prettier/prettier#15718) by [@fisker](https://github.com/fisker))

[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://github.com/tc39/proposal-import-attributes) proposal.

```tsx
import something from "./something.json" with { type: "json" };
```

##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](prettier/prettier#15750) by [@ExplodingCabbage](https://github.com/ExplodingCabbage))

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://github.com/ds300). However, Prettier's documentation (including the CLI `--help` text) continued to claim otherwise, falsely. The documentation is now fixed.

##### Keep curly braces and `from` keyword in empty `import` statements ([#15756](prettier/prettier#15756) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";
```

##### Keep empty import attributes and assertions ([#15757](prettier/prettier#15757) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
```

## [v3.0.3](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#303)

[diff](prettier/prettier@3.0.2...3.0.3)

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](yarnpkg/berry#5411 (comment)) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.

##### Support shared config that forbids `require()` ([#15233](prettier/prettier#15233) by [@fisker](https://github.com/fisker))

If an external shared config package is used, and the package `exports` don't have `require` or `default` export.

In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.

```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in <packageName>/package.json
```

##### Allow argument of `require()` to break ([#15256](prettier/prettier#15256) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```jsx
// Input
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);

// Prettier 3.0.2
const plugin = require(global.STANDALONE
  ? path.join(__dirname, "../standalone.js")
  : path.join(__dirname, ".."));

// Prettier 3.0.3
const plugin = require(
  global.STANDALONE
    ? path.join(__dirname, "../standalone.js")
    : path.join(__dirname, "..")
);
```

##### Do not print trailing commas in arrow function type parameter lists in `ts` code blocks ([#15286](prettier/prettier#15286) by [@sosukesuzuki](https://github.com/sosukesuzuki))

<!-- prettier-ignore -->

````md
<!-- Input -->
```ts
const foo = <T>() => {}
```

<!-- Prettier 3.0.2 -->
```ts

## [v3.0.1](https://github.com/prettier/prettier/blob/HEAD/CHANGELOG.md#301)

[diff](prettier/prettier@3.0.0...3.0.1)

##### Fix cursor positioning for a special case ([#14812](prettier/prettier#14812) by [@fisker](https://github.com/fisker))

<!-- prettier-ignore -->

```js
// <|> is the cursor position

/* Input */
// All messages are represented in JSON.
// So, the prettier.py controls a subprocess which spawns "node {this_file}".
