Please help.

Same problem

[hnitzsche]

npm install buffer

[Vaelor]

npm install buffer

Same issue, installing buffer does not help

[hnitzsche]

try this for testing:

(window as any).global = window;
// @ts-ignore
window.Buffer = window.Buffer || require('buffer').Buffer;

[Vaelor]

Thanks that works. Sounds a bit fishy though :-D

[drechema]

Where do you put that code?

[Vaelor]

@drechema polyfills.ts

Thanks @hnitzsche it works much better now (and I even updated the code to Angular 7)

tried these suggestions, and now I am getting the error, "Class extends value undefined is not a constructor or null"
