`#onnxruntime-webgpu` alias does not resolve for parcel

[PoorRican]

System Info

"@huggingface/transformers": "^3.0.0",
"@parcel/config-webextension": "^2.9.3",
"parcel": "^2.9.3",

Environment/Platform

• Website/web-app
• Browser extension
• Server-side (e.g., Node.js, Deno, Bun)
• Desktop app (e.g., Electron)
• Other (e.g., VSCode extension)

Description

The following error is returned when attempting to build the webextension:

@parcel/core: Failed to resolve '#onnxruntime-webgpu' from './node_modules/@huggingface/transformers/src/backends/onnx.js'

  .../node_modules/@huggingface/transformers/src/backends/onnx.js:29:27
    28 | // @ts-ignore
  > 29 | import * as ONNX_WEB from '#onnxruntime-webgpu';

Overwriting the import to onnxruntime-web fixes the issue.

Reproduction

1. Create project with parcel, @parcel/config-webextension, and @huggingface/transformers.
2. Create basic manifest.json
3. Create a file which imports from @huggingface/transformers
4. Run parcel build ./src/manifest.json

Hi there! 👋 Can you confirm this is maybe not a bug with Parcel itself? If there is a missing configuration mapping I can put in the package.json, there I'd be happy to!

I think you need to add

"@parcel/resolver-default": {
    "packageExports": true
  }

in your package.json to enable subpaths in Parcel.

Thanks @devnook! This looks like what we need. parcel-bundler/parcel#7840 (comment) also recommends this approach (docs here).

@PoorRican does this work for you? I also think we should create an example application in https://github.com/huggingface/transformers.js-examples for this too. If either of you are interested, feel free to open a PR!
