8. @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
9. @ManfredSteyer Standalone Components @Component({ standalone: true, imports: [ […], FlightCardComponent, CityPipe, CityValidator, ], selector: 'flight-search', templateUrl: '…' }) export class FlightSearchComponent { […] }
10. @ManfredSteyer Global Providers bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(LegacyModule), provideRouter(APP_ROUTES), ] });
11. @ManfredSteyer Standalone Component → NgModules @Component({ standalone: true, selector: 'app-root', imports: [ […] TicketsModule, ], templateUrl: '…' }) export class AppComponent { }
12. @ManfredSteyer Standalone Component → NgModules @Component({ standalone: true, selector: 'app-root', imports: [ […] TicketsModule, ], templateUrl: '…' }) export class AppComponent { }
13. @ManfredSteyer NgModule → Standalone Blocks @NgModule({ imports: [ FlightCardComponent, ], declarations: [ MyTicketsComponent ], }) export class TicketsModule { }
14. @ManfredSteyer NgModule → Standalone Blocks @NgModule({ imports: [ FlightCardComponent, ], declarations: [ MyTicketsComponent ], }) export class TicketsModule { }
15. @ManfredSteyer Automatic Migration ng g @angular/core:standalone
16. @ManfredSteyer DEMO
17. @ManfredSteyer More Migrations ng g @angular/core:route-lazy-loading ng g @angular/core:inject-migration
18. @ManfredSteyer #3: Signals
19. @ManfredSteyer Signals: Simple Reactivity Signal as Producer 4711 Consumer read set notify 4712
20. @ManfredSteyer Component With Signals 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>
21. @ManfredSteyer DEMO
22. @ManfredSteyer Stores Streamline Reactive Flow Component Store "Intention" Signal sync/ async computed() computed()
23. @ManfredSteyer NGRX Signal Store export const FlightBookingStore = signalStore( { providedIn: 'root' }, […] );
24. @ManfredSteyer NGRX Signal Store export const FlightBookingStore = signalStore( { providedIn: 'root' }, withState({ from: 'Paris', to: 'London', […] }), […] );
25. @ManfredSteyer NGRX Signal Store export const FlightBookingStore = signalStore( { providedIn: 'root' }, withState({ from: 'Paris', to: 'London', […] }), withComputed(([…]) => ({ […] })), withMethods(([…]) => ({ })), withHooks({ […] }) );
26. @ManfredSteyer DEMO
27. @ManfredSteyer #4: SSR & Hydration

34. @ManfredSteyer @for @for(f of flights; track f.id) { <flight-card [item]="f" [(selected)]="basket[f.id]" /> }
35. @ManfredSteyer @for @for(f of flights; track f.id) { <flight-card [item]="f" [(selected)]="basket[f.id]" /> } @empty { <p>No flights found!</p> }
