Der Router in Angular im Detail betrachtet Manfred Steyer SOFTWAREarchitekt.at
ManfredSteyer
Über mich … • Manfred Steyer • SOFTWAREarchitekt.at • Trainer
& Consultant • Focus: Angular • Google Developer Expert (GDE) Page ▪ 2 Manfred Steyer
Ziel • Den Router kennen lernen • Erweiterte Möglichkeiten kennen
lernen
Inhalt • Basics zu Routing • Child-Routes • Aux-Routes •
Guards • Lazy Loading Page ▪ 4
Motivation Der Router ist der Dreh- und Angelpunkt vieler SPA
Basics Page ▪ 6
Warum Routing? • SPAs bestehen aus einer Seite • Seiten
simulieren Routen • Url sollte auf Route hinweisen • Bookmarks • Back-Button • Router unterstützen hierbei Page ▪ 7
Routing in Angular Page ▪ 8 Logo + Menü Menü
2 Fußzeile SPA Platzhalter
Routing in Angular Page ▪ 10 Logo + Menü Menü
2 Fußzeile SPA Passagier- Komponente /FlugDemo/passagier
Konfiguration Page ▪ 12 const APP_ROUTES: Routes = [ {
path: 'home', component: HomeComponent }, { path: 'flug-suchen', component: FlugSuchenComponent }, { path: '**', redirectTo: 'home' } ]
Konfiguration Page ▪ 13 // app.module.ts @NgModule({ imports: [ BrowserModule,
HttpModule, FormsModule, RouterModule.forRoot(ROUTE_CONFIG) ], […] }) export class AppModule { } Für Root-Module Für Feature-Module: forChild
View von AppComponent Page ▪ 14 <a routerLink="/">Home</a> <a routerLink="/flug-suchen">Flug
suchen</a> <div> <router-outlet></router-outlet> </div>
Parameter • passagier/7 • passagier/7?details=true&page=7 • passagier/7;details=true;page=7 • passagier/7;details=true;page=7/fluege Page
▪ 17
Parameter Page ▪ 18 const APP_ROUTES: Routes = [ […]
{ path: 'flug-suchen', component: FlugSuchenComponent }, { path: 'flug-edit/:id', component: FlugEditComponent } }
Parameter auslesen Page ▪ 19 export class FlugEditComponent { public
id: string; constructor( private route: ActivatedRoute) { route.params.subscribe( p => { this.id = p['id']; […] } ); } […] }
Links auf Routen mit Parameter Page ▪ 20 <a [routerLink]="['/flug-edit',
flug.id]">Edit</a>
DEMO
Hierarchisches Routing Page ▪ 22
Hierarchische Views Page ▪ 23 Logo + Menü Menü 2

Konfiguration Page ▪ 27 const FLIGHT_ROUTES: Routes = [ […]
{ path: 'flug-buchen', component: FlugBuchenComponent, children: [ { path: 'flug-suchen', component: FlugSuchenComponent }, […] ] } ];
DEMO Page ▪ 28 App Home Flug buchen Flug suchen

Aux-Routes Page ▪ 29
Aux-Routes Page ▪ 30 Logo + Menu Menu 2 Footer
SPA Placeholder Named Placeholder
Aux-Routes Page ▪ 31 Logo + Menu Menu 2 Footer
SPA Flight- Component Named Placeholder /FlightApp/flights
Aux-Routes Page ▪ 32 Logo + Menu Menu 2 Footer
SPA Flight- Component Info-Component /FlightApp/flights(aux:info)
Aux-Routes Page ▪ 33 Logo + Menu Menu 2 Footer
SPA Flight- Component Modal-Component /FlightApp/flights(aux:info/modal)
Aux-Routes Page ▪ 34 Logo + Menu Menu 2 Footer
SPA Flight-Edit- Component Modal-Component /FlightApp/flights(aux:info/modal)/17
Use Cases • Modale Dialoge • “Applets” und teilautonome Bereiche
• Commander-Style Page ▪ 35
Platzhalter definieren Page ▪ 36 <router-outlet></router-outlet> <hr> <router-outlet name="aux"></router-outlet> Standard-Name:
primary
Konfiguration Page ▪ 37 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 ▪ 38 <a [routerLink]="[{outlets: { aux: 'info'
}}]"> Activate Info </a> <a [routerLink]="[{outlets: { aux: null }}]"> Deactivate Info </a>
DEMO Page ▪ 40
Guards Page ▪ 41
Was sind Guards? • Services • Werden beim Aktivieren bzw.
Deaktivieren einer Route aktiv • Können Aktivierung und Deaktivierung verhindern Page ▪ 42
Guards Rückgabewert: boolean | Observable<boolean> | Promise<boolean> CanActivate canActivate CanActivateChild
canActivateChild CanLoad canLoad CanDeactivate<T> canDeactivate
Guards in der Konfiguration Page ▪ 45 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 ▪ 46 export const ROUTER_PROVIDERS =
[ { provide: FlugEditGuard, useClass: AdvFlightEditGuard } { provide: AuthGuard, useClass: AdvAuthGuard } ];
Provider für Guards Page ▪ 47 export const ROUTER_PROVIDERS =
[ FlugEditGuard, AuthGuard ]; // app.module.ts @NgModule({ providers: [ ROUTER_PROVIDERS ], […] }) export class AppModule { }
DEMO Page ▪ 48
Lazy Loading
Root Module mit Lazy Loading Page ▪ 56 const APP_ROUTE_CONFIG:
Routes = [ { path: 'home', component: HomeComponent }, { path: 'flights', loadChildren: './[…]flight-booking.module#FlightBookingModule' } ];
Routen für Feature Module Page ▪ 57 const FLUG_ROUTES =
[ { path: '', component: FlugBuchenComponent, […] }, […] } export const FlugRouterModule = RouterModule.forChild(FLUG_ROUTES);
DEMO
Preloading Page ▪ 60
Idee • Eventuell später benötigte Module werden mit freien Ressourcen
vorgeladen • Wird das Modul später tatsächlich benötigt, steht es augenblicklich zur Verfügung Page ▪ 61
Preloading aktivieren Page ▪ 62 RouterModule.forRoot(ROUTE_CONFIG, { preloadingStrategy: PreloadAllModules });
Lazy Loading und Shared Services Page ▪ 63
Lazy Loading und Shared Modules Page ▪ 64 AppModule FlugModule
SharedModule includes includes (lazy) includes
Lazy Loading und Shared Modules Page ▪ 65 AppModule FlugModule
SharedModule includes includes (lazy) includes AuthService AuthService
Lazy Loading und Shared Modules Page ▪ 66 AppModule FlugModule
SharedModule includes includes (lazy) includes AuthService AuthService
Lösung Page ▪ 67 AppModule FlugModule SharedModule includes (lazy) includes
CoreModule includes includes Core-Module soll nur ins AppModule eingebunden werden Globale Provider, wie AuthService & Shell
DEMO
Lösung (für Libraries) Page ▪ 69 AppModule FlugModule AuthModule includes
