title: Angular multiple HTML views on a single component
body: <p>I have an app with very different designs, for mobile and web part and I can't make it with css, so I need two view HTML files on a single component,
  one ts file on two HTML templates, like this:</p>
  
  <pre><code>const mobile = true;
  
  @Component({
   selector: 'app',
   templateUrl: mobile ? './app.component.html' : './mobile-app.component.html',
   styleUrls: mobile ? './app.component.scss' : './mobile-app.component.scss',
  })
  </code></pre>
  
  <p>How can I make it?</p>
