Parcel: 🐛 Changing a Reason file other than the top level one does not trigger rebuild

[aeons]

🐛 bug report

Rebuild on file change doesn't work with Reason, except for the main file in the script tag.

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

bsconfig.json

{
  "name": "example",
  "bs-dependencies": [],
  "bsc-flags": ["-bs-super-errors"],
  "package-specs": {
    "in-source": true,
    "module": "commonjs"
  },
  "reason": {
    "react-jsx": 2
  },
  "refmt": 3,
  "sources": {
    "dir": "src",
    "subdirs": true
  },
  "suffix": ".bs.js",
  "warnings": {
    "error": "+101"
  }
}

parcel --open public/index.html

🤔 Expected Behavior

Changing any .re file that is used in the project triggers a rebuild.

😯 Current Behavior

Nothing happens when a .re file that is not directly included from the html is changed.

💁 Possible Solution

🔦 Context

💻 Code Sample

https://github.com/aeons/parcel-example

Run yarn and yarn start.

Changing something in ./src/index.re triggers a rebuild and reload. Doing the same in ./src/OtherModule.redoes not.

Oh man, there's actually a reason (heh) this happens. How Reason support works in Parcel is it basically requires the corresponding .bs.js file instead of the Reason file. The problem is all .bs.js files require other .bs.js files, not the .re files. This means the dependency graph looks like one .re file and a bunch of .bs.js files. We need a way to mark the .re files as contextual dependencies.

One quick (and ugly ?) trick is to first launch bsb in watch mode (in an other terminal or in the background) and then start parcel:

(bsb -w &) && parcel index.html

Same issue here, it watches the entry point but not any other files :/

Does anyone have the time to make a reproduction of this and validate that it's still an issue with the latest release of parcel@next?
