- Fix the formatting of CSS grid layout properties. Contributed by
[@​denbezrukov](https://togithub.com/denbezrukov)
##### JavaScript APIs
##### Linter
##### Bug fixes
- The `noEmptyBlock` css lint rule now treats empty blocks containing
comments as valid ones. Contributed by
[@​Sec-ant](https://togithub.com/Sec-ant)
- [useLiteralKeys](https://biomejs.dev/linter/rules/use-literal-keys/)
no longer reports quoted member names
([#​3085](https://togithub.com/biomejs/biome/issues/3085)).
Previously
[useLiteralKeys](https://biomejs.dev/linter/rules/use-literal-keys/)
reported quoted member names that can be unquoted.
For example, the rule suggested the following fix:
```diff
- const x = { "prop": 0 };
+ const x = { prop: 0 };
```
This conflicted with the option
[quoteProperties](https://biomejs.dev/reference/configuration/#javascriptformatterquoteproperties)
of our formatter.
The rule now ignores quoted member names.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
-
[noEmptyInterface](https://biomejs.dev/linter/rules/no-empty-interface/)
now ignores empty interfaces in ambient modules
([#​3110](https://togithub.com/biomejs/biome/issues/3110)).
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
-
[noUnusedVariables](https://biomejs.dev/linter/rules/no-unused-variables/)
and
[noUnusedFunctionParameters](https://biomejs.dev/linter/rules/no-unused-function-parameters/)
no longer report the parameters of a constructor type
([#​3135](https://togithub.com/biomejs/biome/issues/3135)).
Previously, `arg` was reported as unused in a constructor type like:
```ts
export type Classlike = new (arg: unknown) => string;
```
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
-
[noStringCaseMismatch](https://biomejs.dev/linter/rules/no-string-case-mismatch/)
now ignores escape sequences
([#​3134](https://togithub.com/biomejs/biome/issues/3134)).
The following code is no longer reported by the rule:
```js
s.toUpperCase() === "\u001b";
```

##### Analyzer
##### New features
- Allow suppression comments to suppress individual instances of rules.
This is
used for the lint rule `useExhaustiveDependencies`, which is now able to
suppress specific dependencies. Fixes
[#​2509](https://togithub.com/biomejs/biome/issues/2509).
Contributed by [@​arendjr](https://togithub.com/arendjr)
##### Enhancements
- Assume `Astro` object is always a global when processing `.astro`
files. Contributed by [@​minht11](https://togithub.com/minht11)
- Assume Vue compiler macros are globals when processing `.vue` files.
([#​2771](https://togithub.com/biomejs/biome/pull/2771))
Contributed by [@​dyc3](https://togithub.com/dyc3)
##### CLI
##### New features
- New `clean` command. Use this new command to clean after the
`biome-logs` directory, and remove all the log files.
```shell
biome clean
```
- Add two new options `--only` and `--skip` to the command `biome lint`
([#​58](https://togithub.com/biomejs/biome/issues/58)).
The `--only` option allows you to run a given rule or rule group,
For example, the following command runs only the
`style/useNamingConvention` and `style/noInferrableTypes` rules.
If the rule is disabled in the configuration, then its severity level is
set to `error` for a recommended rule or `warn` otherwise.
```shell
biome lint --only=style/useNamingConvention
--only=style/noInferrableTypes
```
Passing a group does not change the severity level of the rules in the
group.
All the disabled rules in the group will remain disabled.
To ensure that the group is run, the `recommended` field of the group is
enabled.
The `nursery` group cannot be passed, as no rules are enabled by default
in the nursery group.
The `--skip` option allows you to skip the execution of a given group or
a given rule.
For example, the following command skips the `style` group and the
`suspicious/noExplicitAny` rule.
```shell
biome lint --skip=style --skip=suspicious/noExplicitAny
```
You can also use `--only` and `--skip` together. `--skip` oevrrides
`--only`.
The following command executes only the rules from the `style` group,
but the `style/useNamingConvention` rule.
```shell
biome lint --only=style --skip=style/useNamingConvention
```
These options are compatible with other options such as `--write`
(previously `--apply`), and `--reporter`.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
- Add new command `biome clean`. Use this command to purge all the logs
emitted by the Biome daemon. This command is really useful, because the
Biome daemon tends
log many files and contents during its lifecycle. This means that if
your editor is open for hours (or even days), the `biome-logs` folder
could become quite heavy. Contributed by
[@​ematipico](https://togithub.com/ematipico)
- Add support for formatting and linting CSS files from the CLI. These
operations are **opt-in** for the time being.
If you don't have a configuration file, you can enable these features
with `--css-formatter-enabled` and `--css-linter-enabled`:
```shell
biome check --css-formatter-enabled=true --css-linter-enabled=true ./
```
Contributed by [@​ematipico](https://togithub.com/ematipico)
- Add new CLI options to control the CSS formatting. Check the [CLI
reference page](https://biomejs.dev/reference/cli/) for more details.
Contributed by [@​ematipico](https://togithub.com/ematipico)
- Add new options `--write`, `--fix` (alias of `--write`) and `--unsafe`
to the command `biome lint` and `biome check`.
Add a new option `--fix` (alias of `--write`) to the command `biome
format` and `biome migrate`.
```shell
biome <lint|check> --<write|fix> [--unsafe]
biome format --<write|fix>
biome migrate --<write|fix>
```
The `biome <lint|check> --<write|fix>` has the same behavior as `biome
<lint|check> --apply`.
The `biome <lint|check> --<write|fix> --unsafe` has the same behavior as
`biome <lint|check> --apply-unsafe`.
The `biome format --fix` has the same behavior as `biome format
--write`.
The `biome migrate --fix` has the same behavior as `biome migrate
--write`.
This change allows these commands to write modifications in the same
options.
With this change, the `--apply` and `--apply-unsafe` options are
deprecated.
Contributed by [@​unvalley](https://togithub.com/unvalley)
##### Enhancements
- Biome now executes commands (lint, format, check and ci) on the
working directory by default.
[#​2266](https://togithub.com/biomejs/biome/issues/2266)
Contributed by [@​unvalley](https://togithub.com/unvalley)
```diff
- biome check .
+ biome check # You can run the command without the path
```
- `biome migrate eslint` now tries to convert ESLint ignore patterns
into Biome ignore patterns.
ESLint uses [gitignore
patterns](https://git-scm.com/docs/gitignore#\_pattern_format).
Biome now tries to convert these patterns into Biome ignore patterns.
For example, the gitignore pattern `/src` is a relative path to the file
in which it appears.
Biome now recognizes this and translates this pattern to `./src`.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
- `biome migrate eslint` now supports the `eslintIgnore` field in
`package.json`.
ESLint allows the use of `package.json` as an ESLint configuration file.
ESLint supports two fields: `eslintConfig` and `eslintIgnore`.
Biome only supported the former. It now supports both.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
- `biome migrate eslint` now propagates NodeJS errors to the user.
This will help users to identify why Biome is unable to load some ESLint
configurations.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
- Add a new `--reporter` called `summary`. This reporter will print
diagnostics in a different way, based on the tools (formatter, linter,
etc.) that are executed.
Import sorting and formatter shows the name of the files that require
formatting. Instead, the linter will group the number of rules triggered
and the number of errors/warnings:
Formatter
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The following files needs to be formatted:
main.ts
index.ts
Organize Imports
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The following files needs to have their imports sorted:
main.ts
index.ts
Analyzer
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Some analyzer rules were triggered
Rule Name Diagnostics
lint/suspicious/noImplicitAnyLet 12 (12 error(s), 0 warning(s), 0
info(s))
lint/suspicious/noDoubleEquals 8 (8 error(s), 0 warning(s), 0 info(s))
lint/suspicious/noRedeclare 12 (12 error(s), 0 warning(s), 0 info(s))
lint/suspicious/noDebugger 20 (20 error(s), 0 warning(s), 0 info(s))
Contributed by [@​ematipico](https://togithub.com/ematipico)
- `biome ci` now enforces printing the output using colours. If you were
previously using `--colors=force`, you can remove it because it's
automatically set. Contributed by
[@​ematipico](https://togithub.com/ematipico)
- Add a new `--reporter` called `github`. This reporter will print
diagnostics using [GitHub workflow
commands](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#about-workflow-commands):
::error
title=lint/suspicious/noDoubleEquals,file=main.ts,line=4,endLine=4,col=3,endColumn=5::Use
=== instead of ==
::error
title=lint/suspicious/noDebugger,file=main.ts,line=6,endLine=6,col=1,endColumn=9::This
is an unexpected use of the debugger statement.
::error
title=lint/nursery/noEvolvingAny,file=main.ts,line=8,endLine=8,col=5,endColumn=6::This
variable's type is not allowed to evolve implicitly, leading to
potential any types.
Contributed by [@​ematipico](https://togithub.com/ematipico)
- Add a new `--reporter` called `junit`. This reporter will print
diagnostics using [GitHub workflow
commands](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#about-workflow-commands):

##### Bug fixes
- Fix [#​3024](https://togithub.com/biomejs/biome/issues/3024),
where running `biome init` would create `biome.json` even if
`biome.jsonc` already exists. Contributed by
[@​minht11](https://togithub.com/minht11)
##### Configuration
##### New features
- Add an rule option `fix` to override the code fix kind of a rule
([#​2882](https://togithub.com/biomejs/biome/issues/2882)).
A rule can provide a safe or an **unsafe** code **action**.
You can now tune the kind of code actions thanks to the `fix` option.
This rule option takes a value among:
- `none`: the rule no longer emits code actions.
- `safe`: the rule emits safe code action.
- `unsafe`: the rule emits unsafe code action.
The following configuration disables the code actions of
`noUnusedVariables`, makes the emitted code actions of `style/useConst`
and `style/useTemplate` unsafe and safe respectively.
```json
{
"linter": {
"rules": {
"correctness": {
"noUnusedVariables": {
"level": "error",
"fix": "none"
},
"style": {
"useConst": {
"level": "warn",
"fix": "unsafe"
},
"useTemplate": {
"level": "warn",
"fix": "safe"
}
}
}
}
}
}
```

- Add option `css.formatter`, to control the formatter options for CSS
(and its super languages) files. Contributed by
[@​ematipico](https://togithub.com/ematipico)
- You can now change the severity of lint rules down to `"info"`. The
`"info"` severity doesn't emit error codes, and it isn't affected by
other options like `--error-on-warnings`:
```json
{
"linter": {
"rules": {
"suspicious": {
"noDebugger": "info"
}
}
}
}
```

##### Enhancements
- The `javascript.formatter.trailingComma` option is deprecated and
renamed to `javascript.formatter.trailingCommas`. The corresponding CLI
option `--trailing-comma` is also deprecated and renamed to
`--trailing-commas`. Details can be checked in
[#​2492](https://togithub.com/biomejs/biome/pull/2492).
Contributed by [@​Sec-ant](https://togithub.com/Sec-ant)
##### Bug fixes
- Fix a bug where if the formatter was disabled at the language level,
it could be erroneously enabled by an
override that did not specify the formatter section
[#​2924](https://togithub.com/biomejs/biome/issues/2924).
Contributed by [@​dyc3](https://togithub.com/dyc3)
- Fix [#​2990](https://togithub.com/biomejs/biome/issues/2990),
now Biome doesn't add a trailing comma when formatting `biome.json`.
Contributed by [@​dyc3](https://togithub.com/dyc3)
##### Editors
##### New features
- Add support for LSP Workspaces
##### Enhancements
- The LSP doesn't crash anymore when the configuration file contains
errors. If the configuration contains errors, Biome now shows a pop-up
to the user, and it will only parse files using the default
configuration.
Formatting and linting is disabled until the configuration file is
fixed. Contributed by
[@​ematipico](https://togithub.com/ematipico)
##### Bug fixes
- Fixes [#​2781](https://togithub.com/biomejs/biome/issues/2781),

[@​ah-yu](https://togithub.com/ah-yu)
##### Linter
##### Promoted rules
New rules are incubated in the nursery group. Once stable, we promote
them to a stable group. The following rules are promoted:
-
[useImportRestrictions](https://biomejs.dev/linter/rules/use-import-restrictions/)
- [noNodejsModules](https://biomejs.dev/linter/rules/no-nodejs-modules/)
-
[useArrayLiterals](https://biomejs.dev/linter/rules/use-array-literals/)

[useNamingConvention](https://biomejs.dev/linter/rules/use-naming-convention/)
now supports an option to enforce custom conventions
([#​1900](https://togithub.com/biomejs/biome/issues/1900)).
For example, you can enforce the use of a prefix for private class
members:
```json
{
"linter": {
"rules": {
"style": {
"useNamingConvention": {
"level": "error",
"options": {
"conventions": [
{
"selector": {
"kind": "classMember",
"modifiers": ["private"]
},
"match": "_(.*)",
"formats": ["camelCase"]
}
]
}
}
}
}
}
}

##### Bug fixes
-
[noUndeclaredVariables](https://biomejs.dev/linter/rules/no-undeclared-variables/)
and
[noUnusedImports](https://biomejs.dev/linter/rules/no-unused-imports)
now correctly handle import namespaces
([#​2796](https://togithub.com/biomejs/biome/issues/2796)).
Previously, Biome bound unqualified type to import namespaces.
Import namespaces can only be used as qualified names in a type
(ambient) context.
```ts
// Unused import
import * as Ns1 from "";
// This doesn't reference the import namespace `Ns1`
type T1 = Ns1; // Undeclared variable `Ns1`
// Unused import
import type * as Ns2 from "";
// This doesn't reference the import namespace `Ns2`
type T2 = Ns2; // Undeclared variable `Ns2`
import type * as Ns3 from "";
// This references the import namespace because it is a qualified name.
type T3 = Ns3.Inner;
// This also references the import namespace.
export type { Ns3 }

A constant can be imported as a type and used in a computed member name

computed member name.

##### CLI
##### New features
- Add a command to migrate from ESLint
`biome migrate eslint` allows you to migrate an ESLint configuration to
Biome.
The command supports [legacy ESLint
configurations](https://eslint.org/docs/latest/use/configure/configuration-files)
and [new flat ESLint
configurations](https://eslint.org/docs/latest/use/configure/configuration-files-new).
Legacy ESLint configurations using the YAML format are not supported.
When loading a legacy ESLint configuration, Biome resolves the `extends`
field.
It resolves both shared configurations and plugin presets!
To do this, it invokes *Node.js*.
Biome relies on the metadata of its rules to determine the [equivalent
rule of an ESLint rule](https://biomejs.dev/linter/rules-sources/).
A Biome rule is either inspired or roughly identical to an ESLint rules.
By default, inspired and nursery rules are excluded from the migration.
You can use the CLI flags `--include-inspired` and `--include-nursery`
to migrate them as well.
Note that this is a best-effort approach.
You are not guaranteed to get the same behavior as ESLint.
Given the following ESLint configuration:
```json
{
"ignore_patterns": ["**/*.test.js"],
"globals": { "var2": "readonly" },
"rules": {
"eqeqeq": "error"
},
"overrides": [{
"files": ["lib/*.js"],
"rules": {
"default-param-last": "off"
}
}]
}
```
`biome migrate eslint --write` changes the Biome configuration as
follows:
```json
{
"linter": {
"rules": {
"recommended": false,
"suspicious": {
"noDoubleEquals": "error"
}
}
},
"javascript": { "globals": ["var2"] },
"overrides": [{
"include": ["lib/*.js"],
"linter": {
"rules": {
"style": {
"useDefaultParameterLast": "off"
}
}
}
}]
}
```
Also, if the working directory contains `.eslintignore`, then Biome
migrates the glob patterns.
Nested `.eslintignore` in subdirectories and negated glob patterns are

- Added two new options to customise the emitted output of the CLI:
`--reporter=json` and `--reporter=json-pretty`. With `--reporter=json`,
the diagnostics and the
summary will be printed in the **terminal** in JSON format. With
`--reporter=json-pretty`, you can print the same information, but
formatted using the same options of your configuration.
NOTE: the shape of the JSON is considered experimental, and the shape of
the JSON might change in the future.

- Added new `--staged` flag to the `check`, `format` and `lint`
subcommands.
This new option allows users to apply the command *only* to the files
that are staged (the
ones that will be committed), which can be very useful to simplify
writing git hook scripts
such as `pre-commit`. Contributed by

##### Enhancements
- Improve support of `.prettierignore` when migrating from Prettier
Now, Biome translates most of the glob patterns in `.prettierignore` to
the equivalent Biome ignore pattern.
Only negated glob patterns are not supported.

- Support JavaScript configuration files when migrating from Prettier
`biome migrate prettier` is now able to migrate Prettier configuration
files
ending with `js`, `mjs`, or `cjs` extensions.
To do this, Biome invokes Node.js.
Also, embedded Prettier configurations in `package.json` are now
supported.

- Support `overrides` field in Prettier configuration files when
migrating from Prettier.

- Support passing a file path to the `--config-path` flag or the
`BIOME_CONFIG_PATH` environment variable.
Now you can pass a `.json`/`.jsonc` file path with any filename to the
`--config-path` flag or the
`BIOME_CONFIG_PATH` environment variable. This will disable the
configuration auto-resolution and Biome
will try to read the configuration from the said file path
([#​2265](https://togithub.com/biomejs/biome/issues/2265)).
```shell
biome format --config-path=../biome.json ./src
```

##### Bug fixes
- Biome now tags the diagnostics emitted by `organizeImports` and
`formatter` with correct severity levels, so they will be properly
filtered by the flag `--diagnostic-level`
([#​2288](https://togithub.com/biomejs/biome/issues/2288)).
Contributed by [@​Sec-ant](https://togithub.com/Sec-ant)
- Biome now correctly filters out files that are not present in the
current directory when using the `--changed` flag
[#​1996](https://togithub.com/biomejs/biome/issues/1996).
Contributed by [@​castarco](https://togithub.com/castarco)
- Biome now skips traversing `fifo` or `socket` files
([#​2311](https://togithub.com/biomejs/biome/issues/2311)).
Contributed by [@​Sec-ant](https://togithub.com/Sec-ant)
- Biome now resolves configuration files exported from external
libraries in `extends` from the working directory (CLI) or project root
(LSP). This is the documented behavior and previous resolution behavior
is considered as a bug
([#​2231](https://togithub.com/biomejs/biome/issues/2231)).

##### Configuration
##### Bug fixes
- Now setting group level `all` to `false` can disable recommended rules
from that group when top level `recommended` is `true` or unset.
Contributed by [@​Sec-ant](https://togithub.com/Sec-ant)
- Biome configuration files can correctly extends `.jsonc` configuration
files now
([#​2279](https://togithub.com/biomejs/biome/issues/2279)).

- Fixed the JSON schema for React hooks configuration
([#​2396](https://togithub.com/biomejs/biome/issues/2396)).

##### Enhancements
- Biome now displays the location of a parsing error for its
configuration file
([#​1627](https://togithub.com/biomejs/biome/issues/1627)).
Previously, when Biome encountered a parsing error in its configuration
file,
it didn't indicate the location of the error.
It now displays the name of the configuration file and the range where
the error occurred.
Contributed by [@​Conaclos](https://togithub.com/Conaclos)
- `options` is no longer required for rules without any options
([#​2313](https://togithub.com/biomejs/biome/issues/2313)).
Previously, the JSON schema required to set `options` to `null` when an
object is used to set the diagnostic level of a rule without any option.
However, if `options` is set to `null`, Biome emits an error.
The schema is now fixed and it no longer requires specifying `options`.
This makes the following configuration valid:
```json
{
"linter": {
"rules": {
"style": {
"noDefaultExport": {
"level": "off"
}
}
}
}
}
```

##### Bug fixes
- Biome extension is now able to parse the JSX syntax in files that
associated with the `javascript` [language
identifier](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocumentItem).
