How do I implement advanced router guards in Vue 3?

In Vue 3, you can implement advanced router guards by using the beforeEach, beforeEnter, and afterEach hooks. These allow you to control access to routes based on conditions like authentication or user roles.

Can you give me an example of using a route guard for authentication?

Sure! You can create a beforeEach guard in your router configuration like this:

router.beforeEach((to, from, next) => {
  const isAuthenticated = // your logic to check authentication;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' }); // redirect to login if not authenticated
  } else {
    next(); // proceed to the route
  }
});

What if I want to protect multiple routes with different roles?

You can use route meta fields to specify required roles for each route. Then, in your guard, check the user's role against the required roles:

router.beforeEach((to, from, next) => {
  const userRole = // logic to get user role;
  if (to.meta.roles && !to.meta.roles.includes(userRole)) {
    next({ name: 'Unauthorized' }); // redirect if role is not allowed
  } else {
    next();
  }
});
