@ManfredSteyer @ManfredSteyer 4 #1: ApplicationBuilder esbuild & more

@ManfredSteyer New Generation of Bundlers webpack vite

@ManfredSteyer ng update

@ManfredSteyer … or do it later ng update @angular/cli --name
use-application-builder

@ManfredSteyer @ManfredSteyer 8 #2: Standalone Components

@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

@ManfredSteyer Standalone Components @Component({ standalone: true, imports: [ […], FlightCardComponent,
CityPipe, CityValidator, ], selector: 'flight-search', templateUrl: '…' }) export class FlightSearchComponent { […] }

@ManfredSteyer Global Providers bootstrapApplication(AppComponent, { providers: [ MyGlobalService, importProvidersFrom(LegacyModule), provideRouter(APP_ROUTES),
] });

@ManfredSteyer Standalone Component → NgModules @Component({ standalone: true, selector: 'app-root',
imports: [ […] TicketsModule, ], templateUrl: '…' }) export class AppComponent { }

@ManfredSteyer NgModule → Standalone Blocks @NgModule({ imports: [ FlightCardComponent, ],
declarations: [ MyTicketsComponent ], }) export class TicketsModule { }

await this.flightService.findAsPromise(from, to); this.flights.set(flights); <div *ngFor="let f of flights()"> <flight-card [item]="f" /> </div>

<h2>Welcome to this trial version!</h2> <p>Please sign up to get the full version!</p> } @else { <h2>Welcome!</h2> <p>Please log in!</p> }

@ManfredSteyer @for @for(f of flights; track f.id) { <flight-card [item]="f"
[(selected)]="basket[f.id]" /> }

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

@ManfredSteyer Automatic Migration ng g @angular/core:control-flow
