Ionic 4 Angular 8 - Uncaught ReferenceError: global is not defined

Asked 21/8, 2019 at 7:23 Answered 17/2, 2021 at 18:14

M upgrading my ionic app from Ionic 3 to 4. But I got this error.

I know there are many solutions available in other forums. But they didn't work for me.

I tried (window as any).global = window; but it didn't work.

And I also tried to add Dragula. It didn't work either.

What i am missing? What should I do?

include this

(window as any).global = window;

In your polyfills.ts file

If anyone here with the same issue using Ionic 5 with Angular 10,

Install globalthis:

npm install globalthis

Add:

import 'globalthis/auto';

in polyfills.ts

Note : Adding (window as any).global = window; In polyfills.ts file didn't work in my case
