Securing Angular 2 routes with Auth Guard through canActivate

Securing Angular 2 routes with Auth Guard through canActivate

I've been searching for a solution to this problem for the past 4 hours with no luck.

I have multiple Authguards set up, and I want to instruct the router to grant permission if any of them are true, rather than requiring all guards to be true. Currently, Angular 2 router checks each guard individually before granting permission or blocking access to the link. Is there a better way to approach this issue? Creating several Authentication guards doesn't seem like an ideal solution.

For instance, I want the /profile page to only be accessible by admin and super-user roles, not regular users.

Utilize a single parent Guard to manage multiple guards and retain control:

    @Injectable()
    class MasterGuard implements CanActivate {

      constructor(private firstGuard: Guard1, private secondGuard: Guard2) {}

      canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
        // Assuming that guard1.canActivate() and guard2.canActivate() return a boolean
        return this.firstGuard.canActivate() || this.secondGuard.canActivate();
      }
    }

In your route configuration, simply use the MasterGuard:

{
  path : 'route',
  canActivate : MasterGuard 
  ...
}

Feel free to utilize firstGuard and secondGuard in other routes as well.

If you want to control access to routes, you can utilize the CanLoad interface within an authentication guard. For instance, consider a route setup like this:

{
     path: 'dashboard',
     component: 'DashboardComponent',
     canLoad: [
          AuthGuard
     ]
}

To implement this in your AuthGuard, make sure to include the CanLoad interface. By doing so, if a user lacks permission for a particular route, the modules associated with that route will not load.

export class AuthGuard implements CanLoad {
     canLoad(route: Route): Observable<boolean> | Promise<boolean> | boolean {
          //Here, you would call on your authentication service to verify if the current user has access to this specific route
     }
}

I trust this explanation is helpful. If you have any more questions, feel free to reach out.
