I've taken a lot of time to make sure my app is matching packages and conventions of a fresh cli-rc2 app (ng new) with no luck yet. Much of the app renders fine, I think it's one part of the code that uses compiler.compileModuleAndAllComponentsAsync<any>( this.moduleType ).

Answer 1

Loading children with a function instead of a module string path can cause production builds to raise Runtime compiler is not loaded.

In order to fix the error, look out for loadChildren declarations in the format of:

{
    path: ':id',
    component: MainComponent,
    children: [
      {
        path: '',
        loadChildren: () => SubModule
      }
    ]
  }

and change them to:

  {
    path: ':id',
    component: MainComponent,
    children: [
      {
        path: '',
        loadChildren: './sub-module/sub-module.module#SubModule'
      }
    ]
  }
