8. @ManfredSteyer Standalone Component = Component + NgModule (not implemented that way!)
9. @ManfredSteyer @Component({ standalone: true, selector: 'app-root', imports: [ HomeComponent, AboutComponent, HttpClientModule, ], templateUrl: '…' }) export class AppComponent { […] } @NgModule({ imports: [ HttpClientModule ], declares: [ HomeComponent, AboutComponent ] }) export class AppModule { … } @Component({ selector: 'app-root', templateUrl: '…' }) export class AppComponent { […] }
10. @ManfredSteyer @Pipe({ standalone: true, name: 'city', pure: true }) export class CityPipe implements PipeTransform { […] }
11. @ManfredSteyer @Directive({ standalone: true, selector: 'input[appCity]', providers: [ … ] }) export class CityValidator implements Validator { […] }
12. @ManfredSteyer @Component({ standalone: true, imports: [ […], FlightCardComponent, CityPipe, CityValidator, ], selector: 'flight-search', templateUrl: '…' }) export class FlightSearchComponent { […] }
13. @ManfredSteyer
14. @ManfredSteyer It looks like you want to use NgIfDirective and MyComponent. Shall I import it for you?

18. @ManfredSteyer → @Component({ standalone: true, selector: 'app-root', imports: [ […] TicketsModule, ], templateUrl: '…' }) export class AppComponent { }
19. @ManfredSteyer → @Component({ standalone: true, selector: 'app-root', imports: [ […] TicketsModule, ], templateUrl: '…' }) export class AppComponent { }
20. @ManfredSteyer → @NgModule({ imports: [ FlightCardComponent, ], declarations: [ MyTicketsComponent ], }) export class TicketsModule { }
21. @ManfredSteyer → @NgModule({ imports: [ FlightCardComponent, ], declarations: [ MyTicketsComponent ], }) export class TicketsModule { }
22. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(HttpClientModule), importProvidersFrom(RouterModule.forRoot(APP_ROUTES)), ] });
23. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(HttpClientModule), importProvidersFrom(RouterModule.forRoot(APP_ROUTES)), ] });

26. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ […] ] });
27. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(HttpClientModule), importProvidersFrom(RouterModule.forRoot(APP_ROUTES)), ] });
28. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(HttpClientModule), provideRouter(APP_ROUTES, withPreloading(PreloadAllModules), withDebugTracing(), ), ] });
29. @ManfredSteyer export const APP_ROUTES: Routes = [ […], { path: 'flight-booking', loadChildren: () => import('@nx-example/booking/feature-book') .then(m => m.FLIGHT_BOOKING_ROUTES) }, […] ];
30. @ManfredSteyer export const APP_ROUTES: Routes = [ […], { path: 'flight-booking', loadChildren: () => import('@nx-example/booking/feature-book') .then(m => m.FLIGHT_BOOKING_ROUTES) }, […] ];
31. @ManfredSteyer export const APP_ROUTES: Routes = [ […], { path: 'flight-booking', loadChildren: () => import('@nx-example/booking/feature-book') .then(m => m.FLIGHT_BOOKING_ROUTES) }, { path: 'next-flight', loadComponent: () => import('@nx-example/booking/feature-tickets') .then(m => m.NextFlightComponent) }, ];
32. @ManfredSteyer export const FLIGHT_BOOKING_ROUTES: Routes = [{ path: '', component: FlightBookingComponent, providers: [ MyService ], children: [ […] ] }];
33. @ManfredSteyer export const FLIGHT_BOOKING_ROUTES: Routes = [{ path: '', component: FlightBookingComponent, providers: [ MyService ], children: [ […] ] }]; Scope: This route + all child routes (Lazily) loaded with route config If possible, use providedIn: 'root'
34. @ManfredSteyer export const FLIGHT_BOOKING_ROUTES: Routes = [{ path: '', component: FlightBookingComponent, providers: [ provideState(bookingFeature), provideEffects([BookingEffects]) ], children: [ […] ] }];

38. @ManfredSteyer // index.ts == Public API export * from './flight-booking.routes';

41. @ManfredSteyer + Generates path mappings + Generates initial barrel + Prevents bypassing index.ts + Restricting access between libraries
