Upgrading to angular-6.x gives "Uncaught ReferenceError: global is not defined"
Solution 1:
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
Solution 2:
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: []
};
Example:
<!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
for "Uncaught ReferenceError: global is not defined":
var global = global || window;for "Uncaught ReferenceError: Buffer is not defined":
var Buffer = Buffer || [];for "Uncaught ReferenceError: process is not defined":
var process = process || { env: { DEBUG: undefined } }for "Uncaught TypeError: Cannot read property 'slice' of undefined":
var process = process || { env: { DEBUG: undefined }, version: [] };
Solution 3:
I use HttpClient and accidentally selected the default import which was 'selenium-webdriver/http'
If your app.module.ts has import { HttpClient } from 'selenium-webdriver/http';
Update it to import { HttpClient } from '@angular/common/http';
That fixed my issue.
