    loadChildren: () => ContentModule
  }
];
  • Step 4

Add route to routes in content-routing.module.ts

const routes: Routes = [
  {
    path: '',
    component: ContentComponent,
    children: [
      { path: '', component: DashboardComponent },
    ]
  }
];
  • Step 5

Desired behavior

No error

Note that there is no error with ng serve.

Changing to loadChildren: './content/content.module#ContentModule' in app-routing.module.ts works with ng serve --prod but fails with ng serve. Error below…

Mine was using the template tag ` instead of '. It seems this definition is very very sensitive

Doesn’t work:

loadChildren: () => import(`./home/home.module`).then(m => m.HomeModule)

Works:

loadChildren: () => import('./home/home.module').then(m => m.HomeModule)

It seems like the problem is that the transplier is not handling a multiline format of the arrow function.

This does not work:

{ path: ‘custom’, loadChildren: () => { return import(‘./custom/custom.module’).then(m => m.CustomModule); } }

But This does work:

{ path: ‘custom’, loadChildren: () => import(‘./custom/custom.module’).then(m => m.CustomModule) }

When changing the function to a single line it works with the Angular 8
