9. @ManfredSteyer NgModules + EcmaScript Modules import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { AppComponent } from './app.component'; […] @NgModule({ imports: [BrowserModule, OtherModule], declarations: [AppComponent, OtherComponent, OtherDirective], providers: [], bootstrap: [AppComponent], }) export class AppModule {} TypeScript Modules Angular Modules
10. @ManfredSteyer @Component({ standalone: true, imports: [ […], FlightCardComponent, CityPipe, CityValidator, ], selector: 'flight-search', templateUrl: '…' }) export class FlightSearchComponent { […] }

12. @ManfredSteyer Small and Medium Apps: Folder per Feature
13. @ManfredSteyer Your Public APIs: Barrels // index.ts == Public API export * from './flight-booking.routes';
14. @ManfredSteyer Medium and Large Apps: Folder per Domain
15. @ManfredSteyer Restricting Access b/w Domains, etc. on a library basis

31. @ManfredSteyer @Component({ […] }) export class FlightEditComponent { @Input() id = ''; @Input() showDetails = ''; […] } All you need for getting routing parameters!
32. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ […] provideRouter( APP_ROUTES, withComponentInputBinding(), ), […] }
33. @ManfredSteyer export const APP_ROUTES: Routes = [ { path: 'home', component: HomeComponent, }, { path: 'flight-booking', loadChildren: () => import('./[…]/flight-booking.routes') .then(m => m.FLIGHT_BOOKING_ROUTES) }, ];
34. @ManfredSteyer export const APP_ROUTES: Routes = [ { path: 'home', component: HomeComponent, }, { path: 'flight-booking', loadChildren: () => import('./[…]/flight-booking.routes') .then(m => m.FLIGHT_BOOKING_ROUTES) }, ]; Lazy routing config as default expert
35. @ManfredSteyer export const APP_ROUTES: Routes = [ […] { path: 'flight-booking', canActivate: [() => inject(AuthService).isAuthenticated()], component: FlightBookingComponent }, ]
36. @ManfredSteyer export const APP_ROUTES: Routes = [ […] { path: 'flight-booking', canActivate: [() => inject(AuthService).isAuthenticated()], component: FlightBookingComponent }, ]
37. @ManfredSteyer export const APP_ROUTES: Routes = [ […] { path: 'flight-booking', canActivate: [() => inject(AuthService).isAuthenticated()], resolve: { flights: () => inject(FlightService).findAll() }, component: FlightBookingComponent }, ]
38. @ManfredSteyer export const authInterceptor: HttpInterceptorFn = (req, next) => { […] }
39. @ManfredSteyer bootstrapApplication(AppComponent, { providers: [ provideHttpClient( withInterceptors([authInterceptor]), ), ] });

42. @ManfredSteyer flights: Flight[] = []; const flights = await this.flightService.findAsPromise(from, to); this.flights = flights; <div *ngFor="let f of flights"> <flight-card [item]="f" /> </div>
43. @ManfredSteyer flights = signal<Flight[]>([]); const flights = await this.flightService.findAsPromise(from, to); this.flights.set(flights); <div *ngFor="let f of flights()"> <flight-card [item]="f" /> </div>
44. @ManfredSteyer @Injectable({ providedIn: 'root' }) export class FlightBookingFacade { private flightService = inject(FlightService); private _flights = signal<Flight[]>([]); readonly flights = this._flights.asReadonly(); […] }
45. @ManfredSteyer @Injectable({ providedIn: 'root' }) export class FlightBookingFacade { private flightService = inject(FlightService); private _flights = signal<Flight[]>([]); readonly flights = this._flights.asReadonly(); async load(from: string, to: string) { const flights = await this.flightService.findPromise(from, to); this._flights.set(flights); } […] }
