Use Cases • Modale Dialoge • “Applets” und teilautonome Bereiche
• Commander-Style Page ▪ 41
Platzhalter definieren Page ▪ 42 <router-outlet></router-outlet> <hr> <router-outlet name="aux"></router-outlet> Standard-Name:
primary
Konfiguration Page ▪ 43 export const ROUTE_CONFIG: Routes = [
{ path: 'home', component: HomeComponent }, { path: 'info', component: InfoComponent, outlet: 'aux' }, { path: 'dashboard', component: DashboardComponent, outlet: 'aux' } ]
Aux-Routes routen Page ▪ 44 <a [routerLink]="[{outlets: { aux: 'info'
}}]"> Activate Info </a> <a [routerLink]="[{outlets: { aux: null }}]"> Deactivate Info </a>
Mehrere Outlets gleichzeitig bestücken <a [routerLink]="[{outlets: { aux: 'basket', primary:
'flight-booking/flight-search' }}]"> … </a> <a [routerLink]="[{outlets: { aux: 'basket', primary: ['flight-booking', 'flight-search'] }}]"> … </a> <a [routerLink]="[{outlets: { aux: 'basket', primary: ['flight-booking', 'flight-edit', 17] }}]"> … </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 • Können Aktivierung und Deaktivierung
von Routen 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] }, […] ] ]
Provider für Guards Page ▪ 55 // app.module.ts @NgModule({ providers:
[ FlugEditGuard, AuthGuard ], […] }) export class AppModule { }
DEMO Page ▪ 56
Resolver
Was sind Resolver? • Services • Werden beim Routenwechsel aktiv
• Verzögern Aktivierung der neuen Route • Laden benötigte Daten • 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 } } ];
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 ▪ 64
Warum Lazy Loading? • Module erst bei Bedarf nachladen •
Verbesserung der Start-Performance Page ▪ 65
Root Module mit Lazy Loading Page ▪ 66 const APP_ROUTE_CONFIG:
Routes = [ { path: '', redirectTo: 'home', pathMatch: 'full' }, { path: 'home', component: HomeComponent }, { path: 'flights', loadChildren: '[…]flight-booking.module#FlightBookingModule' } ];
Root Module mit Lazy Loading Page ▪ 67 const APP_ROUTE_CONFIG:
Routes = [ { path: '', redirectTo: 'home', pathMatch: 'full' }, { path: 'home', component: HomeComponent }, { path: 'flights', loadChildren: () => import('[…]flight-booking.module') .then(m => m.FlightBookingModule); } ];
Routen für Feature Module Page ▪ 68 const FLUG_ROUTES =
[ { path: '', component: FlugBuchenComponent, […] }, […] }
Routen für Feature Module Page ▪ 69 const FLUG_ROUTES =
[ { path: 'subroute', component: FlugBuchenComponent, […] }, […] }
DEMO Page ▪ 71
Preloading Page ▪ 72
Idee • Eventuell später benötigte Module werden mit freien Ressourcen
vorgeladen • Wird das Modul später tatsächlich benötigt, steht es augenblicklich zur Verfügung Page ▪ 73
Preloading aktivieren Page ▪ 74 export const AppRoutesModule = RouterModule.forRoot(
ROUTE_CONFIG, { preloadingStrategy: PreloadAllModules });
