I have an Angular 13 App, with uses @auth0/auth0-angular. When I tried to implement SSR, it spits out error that window is not defined. I added the following to server.ts

  const domino = require('domino');
  const fs = require('fs');
  const path = require('path');
  const template = fs.readFileSync(path.join(__dirname, '..', 'browser', 'index.html')).toString();
  const win = domino.createWindow(template);
  global['window'] = win;
  global['document'] = win.document;

This resolved few issues, however after hours of troubleshooting, I came to know that the remaining errors are spit by Auth0, @auth0/auth0-angular.

I read this in @auth0/auth0-angular docs and this in angular-universal docs. I now understand the issue and that there is a solution for it, that has been acknowledged by both the libraries, however I find it hard to implement. I was wondering if there are some sample implementation for the same, of if there is anyone who has already done this?

Any help is appreciated. Thanking you all in anticipation.

  • Both links refer to https://github.com/auth0/auth0-angular#angular-universal. Guess you meant the universal gotchas for the second link https://github.com/angular/universal/blob/main/docs/gotchas.md – Alex Cooper Feb 18 '23 at 10:16

I faced with the same issue, and spent some time for digging into it, here is the possible solution.

Apply those changes to app.server.module:

import * as crypto from 'crypto';
import { createWindow } from 'domino';
import * as fs from 'fs';

if (!global.window) {
  const template = fs.readFileSync('./src/index.html').toString();
  const win = createWindow(template);
  (global as any).window = win;
  (global as any).window.crypto = crypto;
  (global as any).window.isMobileOnServer = true;
  (global as any).document = win.document;
  (global as any).navigator = win.navigator;
  (global as any).location = win.location;
}

Also add a provider

{provide: AuthService, useValue: {}
