What it does
Indicates that a class can implement to be a guard deciding if a children can be loaded.
How to use
class UserToken {} class Permissions { canLoadChildren(user: UserToken, id: string): boolean { return true; } } @Injectable() class CanLoadTeamSection implements CanLoad { constructor(private permissions: Permissions, private currentUser: UserToken) {} canLoad(route: Route( route: Route ): Observable<boolean>|Promise<boolean>|boolean { return this.permissions.canLoadChildren(this.currentUser, route); } } @NgModule({ imports: [ RouterModule.forRoot([ { path: 'team/:id', component: TeamCmp, loadChildren: 'team.js', canLoad: [CanLoadTeamSection] } ]) ], providers: [CanLoadTeamSection, UserToken, Permissions] }) class AppModule {}
You can also provide a function with the same signature instead of the class:
@NgModule({ imports: [ RouterModule.forRoot([ { path: 'team/:id', component: TeamCmp, loadChildren: 'team.js', canLoad: ['canLoadTeamSection'] } ]) ], providers: [ { provide: 'canLoadTeamSection', useValue: (route: Route) => true } ] }) class AppModule {}
