Cannot resolve dependency '_process'

I’m using parcel with this npm script (minifying app.js from compiling PureScript to js):

"prod": "pulp browserify -O --to build/app.js && parcel build build/app.js",

It used to work without problems, but now I always get this error:

> D:\docs\purescript-halogen-template\build\app.js:12147:21: Cannot resolve dependency '_process'
  12145 | PS["Main"].main();

Any idea what is causing this? 😃

Late reply, but yeah, what is needed here is to use pulp build / purs bundle like so: https://github.com/justinwoo/vidtracker/blob/6d651f6b5b378fe239c1a0245c92e5bc8eff8b1d/package.json#L14

Running Parcel on both the normal commonJS /output and a built bundle (not through pulp browserify) has been working well for me for a long time now 👍

@Boscop Parcel is a bundler itself, so there’s no need to run your project through browserify first.Can you please try running it through only Parcel, and see if you’re still getting the error when you run it directly through Parcel without browserify?
