title: Google Firebase WAR file deployment
body: <p>Is it possible to deploy a single WAR file to Google Firebase instead of a whole directory?
  The war file contains the following files:</p>
  
  <ul>
  <li>assets directory</li>
  <li>META-INF directory</li>
  <li>WEB-INF directory</li>
  <li>index.html</li>
  <li>some JS files (chunks, inline, main, polyfills, vendor)</li>
  <li>styles.css</li>
  </ul>
  
  <p>In my case it is an Angular 5 website, that I've build with angular-cli. My current deployment to firebase requires me to upload 19 files (the whole dist directory). I want to reduce that to one WAR file, which I can build with gulp.</p>
