title: Which packages of angular are present in the final build
body: <p>I would like to know if there is a tool to track packages that are present in the final build of an angular project.</p>
  <p><strong>For example</strong> :
  I have a package <strong>&quot;@angular/compiler&quot;</strong> which is a dependency of the package.json but not a dev dependency.</p>
  <p>As mentioned on the angular docs <a href="https://angular.io/guide/aot-compiler#ahead-of-time-aot-compilation" rel="nofollow noreferrer">https://angular.io/guide/aot-compiler#ahead-of-time-aot-compilation</a> with <strong>AOT compiler</strong> code is already compiled, unlike JIT compiler. In my understanding, it means that the final build does not need @angular/compiler as a dependency if the flag AOT is set for the final build.</p>
  <p>Is my reasoning is correct?</p>
