Can you double check if this fixs the polyfill problem? I'm still getting the error building with angular.

Although seems like CRA builds work fine on 4.x main branch, not sure why.

I tried it with CRA and it worked. Could you paste angular error and link to repo with angular repo?

For end users few options are, users adding explicitly in polyfills.ts :

(window as any).process = {
  env: { DEBUG: undefined },
};

or

yarn add process
and after that adding explicitly in polyfills.ts :

import * as process from 'process';
window['process'] = process;

[mpetrunic]

yarn link add web3

There is no way around it except for #6156
