title: Checking for template errors of an Angular app without bundling
body: <p>We have a CI/CD pipeline on Gitlab that runs on every commit where want to check the project for Typescript and template (mainly template) errors. We are currently using <code>ng build --prod</code> but it takes forever because it is also bundling the source code (currently 20min. On my machine it takes 2 min).</p>
  
  <p><strong>Is it possible to run only the 'first part' of the <code>ng build --prod</code> where it only checks only for Typescript and template errors?</strong> This will make our pipeline faster.</p>
