Angular 2 Router Guards & Resolver

Route guards

routes protégées par identification - voir l'exemple

Il est possible de définir une phase de vérification avant l'ouverture / la fermeture ou le chargement d'une route.

// définition de la route
{
    path: 'home', component: HomeScreenComponent,
    canActivate: [CanActivateAuthProtected]
    canActivateChild: [CanActivateChildRightProtected]
    candDeactivate: [CanCloseFormRoute],
    candLoad: [CanLoadOtherModule],
}

Cf. src/app/auth/CanActivateAuthProtected » une simple classe de vérification de droits d'accès à une route

Route data resolver

Les resolver permettent de préparer les données nécessaires à une vue durant l'ouverture d'une route.

{
        path: 'home', component: HomeScreenComponent,
        canActivate: [CanActivateAuthProtected],
        resolve:{
            user: CurrentUserResolver
        }
    },

La classe CurrentUserResolver doit implémenter Resolve :

@Injectable()
export class CurrentUserResolver implements Resolve<any>{
    constructor(private service:AuthService) {}

    resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any>|Promise<any>|any {
        return this.service.getUserInfos(route.params['id']) ;
    }
}
