Here docs https://github.com/webpack/changelog-v5#automatic-nodejs-polyfills-removed

Plus you can use alias for this https://webpack.js.org/configuration/resolve/#resolvealias

Thanks!

Also came across this!

@evilebottnawi So I'm able to load my own Node polyfills and that's working great

I ran into another situation that's pretty interesting, I'm depending on this library which is using process.cwd() as a global (not importing process) ... and so my process mocks aren't loaded

Any ideas on how to solve or mock this use case?

If this is something that Webpack isn't concerned about, I'm happy to move this issue you to the other libraries repo, but figured this may be something that a lot of users migrating to WP5 will run into.

You need to open an issue in library for browsing supporting or you can use https://www.npmjs.com/package/process (just put import 'process';), some libraries can be incompatibility with browsers env, we can't fix it

Thanks @evilebottnawi I'll move my issue to the other repo

Found solution for Angular and particularly sockJS nested dev-dependency of eventsource lib. Perhaps not the prettiest solution, though but it still works.
node: 16.20.2
npm: 8.19.4 (please aware, override works only with npm >= v8.3)

So you need the following steps:

1. Install https://www.npmjs.com/package/event-source-polyfill
2. Override required dependencies in package.json, in my case it was:

"overrides": {
    "sockjs-client": {
      "eventsource": "npm:event-source-polyfill"
    } 

So it changes your nested dependency by entirely different lib.
