How do I implement role-based access control in Vue 3 using router guards?

To implement role-based access control in Vue 3, you can use router guards to check user roles before allowing access to certain routes.

Can you show me an example of how to set up a router guard for this?

Sure! You can define a global beforeEach guard in your router configuration. Here's a basic example:

router.beforeEach((to, from, next) => {
  const userRole = getUserRole(); // Function to get the user's role
  if (to.meta.requiresAuth && to.meta.role && to.meta.role !== userRole) {
    next({ name: 'Unauthorized' }); // Redirect to an unauthorized page
  } else {
    next(); // Proceed to the route
  }
});

What if I want to allow multiple roles to access a route?

You can modify the guard to check if the user's role is included in an array of allowed roles. For example:

if (to.meta.requiresAuth && to.meta.roles && !to.meta.roles.includes(userRole)) {
  next({ name: 'Unauthorized' });
}
