What is @angular/router?
The @angular/router package provides navigation and URL manipulation capabilities for Angular applications. It allows developers to define routes, navigate between them, handle route parameters, and guard routes among other functionalities.
What are @angular/router's main functionalities?
Route Configuration
Defines routes in an Angular application, associating paths with components.
const routes: Routes = [
{ path: 'home', component: HomeComponent },
{ path: 'about', component: AboutComponent }
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
Router Outlet
A placeholder that Angular dynamically fills based on the current router state.
<router-outlet></router-outlet>
Navigation
Programmatically navigate to different routes within an Angular application.
constructor(private router: Router) { }
navigateToHome() {
this.router.navigate(['/home']);
}
Route Parameters
Access parameters for a given route, often used for fetching data based on the URL.
constructor(private route: ActivatedRoute) { }
ngOnInit() {
this.route.paramMap.subscribe(params => {
this.userId = params.get('id');
});
}
Route Guards
Protect routes with guards that can allow or prevent navigation to a route based on logic such as authentication.
@Injectable({ providedIn: 'root' })
export class AuthGuard implements CanActivate {
canActivate(
next: ActivatedRouteSnapshot,
state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {
return this.authService.isAuthenticated();
}
}
