Upgrading to angular-6.x gives “Uncaught Reference

I upgraded my project from angular-5.x to angular-6.x and it started giving the following error and even creation of dummy global variable does not work as given here Angular 6 Auth0 - global not defined

The error is as follows:

Uncaught ReferenceError: global is not defined
    at Object../node_modules/has-binary2/index.js (index.js:10)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/socket.io-parser/index.js (index.js:8)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/socket.io-client/lib/index.js (index.js:7)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/app4pc/apiConnection/services/ApiConnectionServer.ts (auth.interceptor.ts:8)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/app4pc/apiConnection/toServer.module.ts (ApiConnectionServer.ts:11)
    at __webpack_require__ (bootstrap:81)

after resolving this I get following error:

Uncaught ReferenceError: process is not defined
    at Object../node_modules/process-nextick-args/index.js (index.js:3)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/readable-stream/lib/_stream_readable.js (_stream_readable.js:26)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/readable-stream/readable-browser.js (readable-browser.js:1)
    at __webpack_require__ (bootstrap:81)
    at Object../node_modules/simple-peer/index.js (index.js:7)
    at __webpack_require__ (bootstrap:81)
    at Object../src/app/util/services/call.services.ts (notification.service.ts:12)
    at __webpack_require__ (bootstrap:81)

And continues on and on.

Add following code in your starting page e.g. index.html

var global = global || window;
    var Buffer = Buffer || [];
    var process = process || {
      env: { DEBUG: undefined },
      version: []
    };

e.g. follows:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Client</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
  <script>
    var global = global || window;
    var Buffer = Buffer || [];
    var process = process || {
      env: { DEBUG: undefined },
      version: []
    };
  </script>
</head>
<body>
  <app-root>
    <div class="loader"></div>
  </app-root>
</body>
</html>

Above will work on hybrid app(in node environment) as well as in browser

var global = global || window; // for Uncaught ReferenceError: global is not defined

var Buffer = Buffer || []; // for Uncaught ReferenceError: Buffer is not defined

var process = process || { env: { DEBUG: undefined } } // for Uncaught ReferenceError: process is not defined

var process = process || { env: { DEBUG: undefined }, version: [] }; // Uncaught TypeError: Cannot read property 'slice' of undefined

Adding this line to polyfills.ts should resolve node global error

(window as any).global = window;

The solution was mentioned in this angular-cli issue thred
