title: How to load Angular 8 components which are not generated with CLI, automatically?
body: <p>I would like to know if there is an easy way to load Angular 8 components which are not created with CLI on my application without having to add them by myself in :</p>
  
  <pre class="lang-js prettyprint-override"><code>@NgModule({
    declarations: [
      AppComponent,
      DashboardComponent,
      MapComponent,
      PluginComponent,
    ],
  </code></pre>
  
  <p>For example I would like: <code>PluginTestComponent</code> to be added in this list.
  If there is not a native way, I was thinking to edit the file before the app is launched.</p>
  
  <p>I may not going in the good way too: my final goal is to have a dashboard where I can load components on it, where components can be created by extern people without having access to the src and can just upload their components on a specific folder.</p>
  
  <p>I'm all hear for advices or solutions.</p>
