Inhalt • Basics zu Routing • Child-Routes • Aux-Routes •
Guards • Resolver • Lazy Loading • Preloading Page ▪ 4
Didaktik • Präsentation • Live Coding
Motivation Der Router ist der Dreh- und Angelpunkt vieler SPA

Routing unter Angular Page ▪ 9 Logo + Menü Menü
2 Fußzeile SPA Passagier- Komponente /FlugDemo#passagier
Routen via Hash-Fragment • /FlugDemo#passagier • Hash-Fragment wird nie zum
Server gesendet Page ▪ 10
Routen via History API • /FlugDemo/passagier • Gesamte Url wird
zum Server gesendet • Server antwortet mit SPA • Server kann erste Ansicht "vorrendern" • Performance, SEO, … • SPA informiert Browser über Grenze zwischen (eigentlicher) Url und Route Page ▪ 11
Parameter • passagier/7 • passagier/7?details=true&page=7 • passagier/7;details=true;page=7 • passagier/7;details=true;page=7/fluege Page

Aux-Routes routen Page ▪ 45 <a [routerLink]="[{outlets: { aux: 'info',
primary: 'flight-search' }}]"> Activate Info </a> <a [routerLink]="[{outlets: { aux: null }}]"> Deactivate Info </a>
Programmatisch routen Page ▪ 46 export class AppComponent { constructor(private
router: Router) { } activateInfo() { this.router.navigate([{outlets: { aux: 'info' }}]); } deactivateInfo() { this.router.navigate([{outlets: { aux: null }}]); } }
DEMO Page ▪ 47
Guards Page ▪ 48
Was sind Guards? • Services • Werden beim Aktivieren bzw.
Deaktivieren einer Route aktiv • Können Aktivierung und Deaktivierung verhindern Page ▪ 49
Guards Rückgabewert: boolean | Observable<boolean> | Promise<boolean> CanActivate canActivate CanActivateChild
canActivateChild CanLoad canLoad CanDeactivate<T> canDeactivate
Guards in der Konfiguration Page ▪ 52 const APP_ROUTES: Routes
= [ { path: '/flug-buchen', component: FlugBuchenComponent, canActivate: [AuthGuard], children: [ { path: 'flug-edit/:id', component: FlugEditComponent, canDeactivate: [FlugEditGuard] }, […] ] ] Token
Provider für Guards Page ▪ 53 // app.module.ts @NgModule({ providers:
[ { provide: FlugEditGuard, useClass: AdvFlightEditGuard } { provide: AuthGuard, useClass: AdvAuthGuard } ], […] }) export class AppModule { }
Provider für Guards Page ▪ 54 // app.module.ts @NgModule({ providers:
[ FlugEditGuard, AuthGuard ], […] }) export class AppModule { }
DEMO Page ▪ 55
Resolver
Was sind Resolver? • Services • Werden beim Routenwechsel aktiv
• Laden benötigte Daten • Verzögern Aktivierung der neuen Route • Zwischenzeitlich kann z. B. Loading Indikator angezeigt werden
Resolver @Injectable() export class FlightResolver implements Resolve<Flight> { constructor(private flightService:
FlightService) { } resolve(route, state): Observable<Flight> | Promise<Flight> | Flight { return […] } }
Resolver registrieren const FLIGHT_BOOKING_ROUTES: Routes = [ […] { path:
'flight-edit/:id', component: FlightEditComponent, resolve: { flight: FlightResolver } } ]; Token
Daten entgegennehmen @Component({ … }) export class FlightEditComponent { flight:
Flight; constructor(private route: ActivatedRoute) { } ngOnInit() { this.route.data.subscribe( data => { this.flight = data['flight']; } ); } }
DEMO
Lazy Loading Page ▪ 63
Warum Lazy Loading? • Module erst bei Bedarf nachladen •
Verbesserung der Start-Performance Page ▪ 64
Root Module mit Lazy Loading Page ▪ 65 const APP_ROUTE_CONFIG:
Routes = [ { path: '', redirectTo: 'home', pathMatch: 'full' }, { path: 'home', component: HomeComponent }, { path: 'flights', loadChildren: '[…]flight-booking.module#FlightBookingModule' } ];
Routen für Feature Module Page ▪ 66 const FLUG_ROUTES =
[ { path: '', component: FlugBuchenComponent, […] }, […] } export const FlugRouterModule = RouterModule.forChild(FLUG_ROUTES);
DEMO Page ▪ 67
Preloading Page ▪ 68
Idee • Eventuell später benötigte Module werden mit freien Ressourcen
vorgeladen • Wird das Modul später tatsächlich benötigt, steht es augenblicklich zur Verfügung Page ▪ 69
Preloading aktivieren Page ▪ 70 export const AppRoutesModule = RouterModule.forRoot(
ROUTE_CONFIG, { preloadingStrategy: PreloadAllModules });
Lazy Loading und Shared Services Page ▪ 71
