title: Angular 13 - What replaces DeployURL
body: <p>I've just upgraded a project to angular 13, and it removed my &quot;deployUrl&quot; option under serve. What's replacing this ?</p>
  <p>For context my prod deployments are under a path (/appname/) so I have that in the deployUrl for build, but that's a bit annoying when using ng serve during development so I was using a different deployUrl (just /) in serve.</p>
  <p>Without it I have to use localhost:4200/appname/ when using ng serve, which isn't the end of the world but a bit annoying.</p>
  <p>Thanks</p>
