@parcel/config-webextension missing dependency @parcel/transformer-raw

[ksmithut]

🐛 bug report

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

.parcelrc

{
  "extends": "@parcel/config-webextension"
}

command

parcel build src/manifest.json src/devtools/panel/panel.html --dist-dir dist

🤔 Expected Behavior

I would expect there to not be an error when running build

😯 Current Behavior

When trying to run a parcel build (2.0.0-rc.0) using the @parcel/config-webextension an error message pops up:

@parcel/core: Could not determine version of @parcel/transformer-raw in node_modules/@parcel/config-webextension/index.json. Either include it in "dependencies" or "parcelDependencies".

The dependencies in the package.json for @parcel/config-webextension:

  "dependencies": {
    "@parcel/config-default": "2.0.0-rc.0",
    "@parcel/packager-raw-url": "2.0.0-rc.0",
    "@parcel/transformer-webextension": "2.0.0-rc.0"
  },

which indeed does not include @parcel/transformer-raw

💁 Possible Solution

Add the dependency to @parcel/config-webextension

It also looks like this error only shows up when you use the "default_locale": "en", option in the manifest.json

🔦 Context

Keeping my dependencies on the bleeding edge. Little bit of blood, but not too much :) that's what release candidates are for!

💻 Code Sample

package.json

{
  "scripts": {
    "build": "parcel build manifest.json"
  },
  "dependencies": {
    "@parcel/config-webextension": "^2.0.0-rc.0",
    "parcel": "^2.0.0-rc.0"
  }
}

.parcelrc

{
  "extends": "@parcel/config-webextension"
}

manifest.json

{
  "manifest_version": 2,
  "name": "__MSG_extensionName__",
  "version": "0.0.0",
  "default_locale": "en",
  "description": "__MSG_extensionDescription__"
}

_locales/en/messages.json

{
  "extensionName": {
    "message": "test name",
    "description": "The name of the extension."
  },
  "extensionDescription": {
    "message": "test description",
    "description": "The description of the extension."
  }
}

yarn # or npm i
yarn build # or npm run build

This is maybe a different issue, but if I get it to successfully build by taking out the default_locale option, I get a warning in the console:

console: 
"extendDefaultPlugins" utility is deprecated.
Use "preset-default" plugin with overrides instead.
For example:
{
  name: 'preset-default',
  params: {
    overrides: {
      // customize plugin options
      convertShapeToPath: {
        convertArcs: true
      },
      // disable plugins
      convertPathData: false
    }
  }
}

Edit: Seems unrelated. I started using "targets" in my package.json and this warning went away.
