OK. I found a way to properly Polyfill the “process is not defined”

npm install -S process

the add the following to your polyfills.ts

import * as process from ‘process’; window[‘process’] = process;

and set tsconfig.json

"target": "es2015",

Solved with adding following to polyfills.ts

// window.process needed by aws-amplify
(window as any).process = { browser: true };

as this is the same definition as aws browser loader tries to apply but fails because of undefined process. see aws-sdk/lib/browser_loader.js:L35

if (typeof process === 'undefined') {
  process = {
    browser: true
  };
}
