Plugin resolver: Forbids resolving # - because of subpathImports?

[Carnageous]

Hey! I'm switching a monorepo to use nodejs subpath imports (prefixed with #) instead of tsconfig paths.

Now, I want to use the # for import paths in scss files as well. The plan was to use vite's resolver plugin alias like we did before (we used the $ before, and it worked great).

It seems like vite doesn't support this? Looking at the sourcecode, it looks like vite is just not resolving anything that starts with a #. There is one comment mentioning We don't support '#' in user source code. So is there no way to resolve paths like this?

See https://stackblitz.com/edit/vitejs-vite-suxihvhf?file=vite.config.ts for an example. pnpm dev runs it with debug mode, so you can see that vite:resolve isn't doing anything for those imports.

I understand by the way that the code that actually handles this is rollup-plugin-alias, but I cannot find anything they do to prevent handling "#"

I'm not sure if this is necessary intended or if there's any blocker. Please feel free to create an issue.

It's possible that this is sass/scss specific thing (which is known to have certain limitation in custom resolver such as #19042), so it would be nice to know if other files (js, css, ...) have the same issue.

For future readers: I opened an issue here #19560 (comment), and it seems to be a known issue with the sass modern API. Closing this.
