declare module inside .d.ts does not get picked up by Deno

[Mqxx]

Hey, I currently have a problem when importing non js/ts files inside a js/ts file. deno-ts shows an error with non-resolvable imports for non-js/ts files.

For example i have this index.ts files, somewhere in my project:

import styles from './hello_world.scss'
//     ^
//     Error: Module '"hello_world.scss"' has no default export. deno-ts(1192)

This behavior is correct because scss does not have a valid default export.

However, if I now create an index.d.ts file in the root of my project with the following content, the error still occurs. Deno simply ignores this file.

declare module '*.scss';

or

declare module '*.scss' {
  const content: string;
  export default content;
}

Neither of the two contents work. Also adding the .d.ts file to the types array in the compilerOptions did not help.

It would be really great if this error could be fixed or if this could be added as a feature.

• Deno version used: 1.41.3

There's also an older (closed) issue: #15132
Having to prefix fancy imports with @ts-types comments really sucks, but at least it works.

currently running on Deno 2.0.6. This is still an issue for me.

My two use cases are:

• unocss, having to import virtual:uno.css.
• imagetools, importing *.*&imagetools.

I used to just declare these in a custom types.d.ts. Now it's just errors :(

Still persistent in latest Deno version (v2.1.1)

Same on 2.1.2. I wasted few hours trying to fix it today :(

some types from esm.sh are broken by the issue too.

declare module 'highlight.js/private' {
   // ...
}
declare module 'https://esm.sh/highlight.js@11.9.0/types/index.d.ts' {
    import { KeywordDict } from "highlight.js/private";
    // ...
}

error output:

error: Relative import path "highlight.js/private" not prefixed with / or ./ or ../
