How can I implement role-based access control in my Angular app using Auth0?

To implement role-based access control in your Angular app with Auth0, you can use Auth0's roles feature. First, define roles in your Auth0 dashboard, then assign these roles to users. In your Angular app, you can check the user's roles after authentication and restrict access to certain routes or components accordingly.

Can you show me an example of how to check user roles in Angular?

Sure! After authenticating the user, you can retrieve their roles from the JWT token. Use a service to decode the token and check the roles like this:

import jwt_decode from 'jwt-decode';

const token = localStorage.getItem('access_token');
const decodedToken = jwt_decode(token);
const userRoles = decodedToken['https://your-app.com/roles'];

if (userRoles.includes('admin')) {
  // Grant access to admin features
}

What if I want to restrict access to a specific route based on roles?

You can use Angular's route guards to restrict access. Create a guard that checks the user's roles and use it in your routing module:

import { CanActivate } from '@angular/router';

@Injectable({ providedIn: 'root' })
export class RoleGuard implements CanActivate {
  constructor(private authService: AuthService) {}

  canActivate(): boolean {
    const userRoles = this.authService.getUserRoles();
    return userRoles.includes('admin');
  }
}
