Importing modules with "object style" exports fails

[david-nordvall]

I'm not sure if this is an issue with parcel-transformer-svelte3-plus or with Parcel (more specifically, @parcel/resolver-default). But I'll post this issue here as a start :-).

I am unable to import modules that are exported using object style export in its package.json from my Svelte 4 applications (bundled using Parcel and parcel-transformer-svelte3-plus), such as:

{
  "export": {
    ".": {
      "types": "./dist/index.d.ts",
      "svelte": "./dist/index.js"
    }
  }
}

This fails event though I have enabled the new package exports with the following snippet in my package.json:

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

More details and a reproduction of the error is available in the repo david-nordvall/parcel-resolver-exports-bug.

This is because the Parcel resolver doesn't know to use the svelte export condition, and there's no way for you or a transformer plugin to tell it to do that. I reported it as parcel-bundler/parcel#10050.
