V2: Fails to resolve wasm file from node module

[xzilja]

🐛 bug report

🎛 Configuration (.babelrc, package.json, cli command)

This is a nested package.json inside a monorepo packages/app/package.json

{
  "name": "my-app",
  "version": "1.0.0",
  "private": true,
  "browser": "dist/index.html",
  "source": "public/index.html",
  "engines": {
    "browsers": "Chrome 80, Safari 13.1"
  },
  "alias": {
    "$app": "./src",
    "$images": "./public/images"
  },
  "scripts": {
    "clean": "rm -rf dist",
    "start": "parcel serve ./public/index.html",
    "build": "yarn clean; parcel build ./public/index.html",
  },
  "dependencies": {
    "stretch-layout": "0.3.2"
  },
  "devDependencies": {}
}

🤔 Expected Behavior

I am importing and using wasm library for https://github.com/vislyhq/stretch, since it says that parcel supports wasm out of the box I expected there to be no build errors.

😯 Current Behavior

When I'm trying to start or build an app I get an error:

🚨 Build failed.
@parcel/core: Failed to resolve './stretch_layout_bg' from './node_modules/stretch-layout/stretch_layout.js'
/Users/ilja/Documents/GitHub/skimitar-tmp/node_modules/stretch-layout/stretch_layout.js:1:23
> 1 | import * as wasm from './stretch_layout_bg';
>   |                       ^^^^^^^^^^^^^^^^^^^^^
  2 | 
  3 | /**
@parcel/resolver-default: Cannot load file './stretchlayout_bg' in './nodemodules/stretch-layout'.

I also tried to slap .wasm on the end of stretchlayout_bg layout thinking that maybe parcel needs it to resolve this correctly, but had no luck:

🚨 Build failed.
Error: No transformers found for "/Users/ilja/Documents/GitHub/skimitar-tmp/nodemodules/stretch-layout/stretch_layoutbg.wasm".

💁 Possible Solution

Not sure, is this functionality implemented in parcel v2 or is it still on the roadmap?

🔦 Context

Trying to use wasm library in parcel, was under assumption this is supported out of the box, but is currently failing.

💻 Code Sample

You can import anything from this library to trigger an error i.e.

import { Allocator, Node } from 'stretch-layout';

🌍 Your Environment

is it still on the roadmap

Yes, it's unfortunately still not implemented (#647, #1325)

[sighWang]

can parcel import wasm from node_modules right now?

[XSPGMike]

looks like it still can't be done, there is no transformer for wasm right now.
you can import the file anyway by prepending url to the wasm file location.
import fileName from 'url:../node_modules/package/file.wasm'
