title: Angular 13 live-reload not working, can websocket endpoint be configured?
body: <p>It seems like the path Angular uses for the its websocket in the dev build has changed.</p>
  <p>Angular 12 &amp; earlier: <code>ws://localhost:4200/websocket</code></p>
  <p>Angular 13: <code>ws://localhost:4200/ws</code></p>
  <p>This causes our app a problem because we use <code>/ws</code> for a websocket connection with our backend. We connect to our backend via a proxy, so the connection with both our server and Angular is <code>ws://localhost:4200/ws</code>. The path gets proxied, so Angular live-reload does not work.</p>
  <p>Can the Angular websocket endpoint be configured?</p>
