How can I implement roles and permissions in a Vue.js app using Auth0?

To implement roles and permissions in a Vue.js app with Auth0, you can use Auth0's RBAC (Role-Based Access Control) feature. First, define roles in your Auth0 dashboard, then assign those roles to users. In your Vue.js app, you can retrieve the user's roles from the ID token and use them to control access to different parts of your application.

Can you show me an example of how to check a user's role in Vue.js?

Sure! You can decode the ID token using a library like jwt-decode. Here's a simple example:

import jwtDecode from 'jwt-decode';

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

if (userRoles.includes('admin')) {
  // Show admin features
} else {
  // Show regular user features
}

What if I want to restrict access to certain routes based on roles?

You can use Vue Router's navigation guards to restrict access. For example:

router.beforeEach((to, from, next) => {
  const token = localStorage.getItem('access_token');
  const decodedToken = jwtDecode(token);
  const userRoles = decodedToken['https://your-app.com/roles'];

  if (to.meta.requiresAuth && !userRoles.includes('admin')) {
    next({ name: 'Home' }); // Redirect to home if not authorized
  } else {
    next(); // Proceed to the route
  }
});
