title: MIME type issue in Angular
body: <p>I am getting the following error when I try to load my home page and the page is blank.</p>

  <p>This was working before and it is working correctly in dev while serving using <code>ng serve</code>. The issue happens when the code is running from server. When I checked from the devtools, it is showing the <code>content-type</code> and <code>text/html</code> instead of <code>application/javascript</code>. How this can be fixed ? There is something needs to be set from the server ?</p>
