Functional resolver patterns
Combine resolvers with guards
Error and redirect handling

Angular Route Resolvers

Best Practices

Create functional resolver

export const userResolver: ResolveFn<User> = (route, state) => {
  const userService = inject(UserService);
  const userId = route.paramMap.get('id');
  return userService.getUser(userId!);
};

Use resolver in route

const routes: Routes = [
  {
    path: 'user/:id',
    resolve: { user: userResolver },
    component: UserComponent
  }
];

Get resolved data in component

@Component({})
export class UserComponent {
  private route = inject(ActivatedRoute);
  
  user = this.route.snapshot.data['user'];
  
  // Or with input binding (Angular 17+)
  userId = input<string>();
}

Handle resolver errors

export const dataResolver: ResolveFn<Data> = (route, state) => {
  const service = inject(DataService);
  return service.getData().pipe(
    catchError(() => of(null))
  );
};

Use multiple resolvers

const routes: Routes = [
  {
    path: 'dashboard',
    resolve: {
      user: userResolver,
      settings: settingsResolver
    },
    component: DashboardComponent
  }
];
