This package was published to address a parcel issue that made the bundler to stop watching elm files after a compilation error.

That issue was addressed with this pr, so now nobody should rely on this ugly hack.

Anyway, to play around with this, you'll need to yarn add --dev parcel-transformer-elm and put something like this in your .parcelrc:

{
  "extends": "@parcel/config-default",
  "transformers": {
    "*.elm": ["parcel-transformer-elm"]
  }
}
