We have updated our Angular 7 app to Angular 12 by using the migration steps from the angular website. The Angular CLI on npm start gives us only a warning

'node-sass' usage is deprecated and will be removed in a future major version. To opt-out of the deprecated behaviour and start using 'sass' uninstall 'node-sass'.

But if we start our app we get the following error:

util.js:109 Uncaught ReferenceError: process is not defined
at Object.71732 (util.js:109)
at __webpack_require__ (bootstrap:19)
at Module.77741 (documents.component.ts:19)

at __webpack_require__ (bootstrap:19)
at Module.65790 (not-found.component.ts:10)
at __webpack_require__ (bootstrap:19)

Have haven't found anything how can I solve this issue and I get a blank page.

angular webpack typescript

Add following to your polyfill.ts file:

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