How can I implement advanced features in Vue 3 router guards?

In Vue 3, you can implement advanced features in router guards by using navigation guards like beforeEach, beforeEnter, and afterEach. These allow you to control access to routes based on conditions.

Can you give me an example of using beforeEach for authentication?

Sure! You can use beforeEach to check if a user is authenticated before allowing access to certain routes. Here's a simple example:

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 about using afterEach for logging?

AfterEach can be used for logging or performing actions after a route has been resolved. Here's an example:

router.afterEach((to, from) => {
  console.log(`Navigated to ${to.path} from ${from.path}`);
});

Are there any performance considerations I should be aware of?

Yes, be cautious with heavy computations in guards, as they can slow down navigation. Keep your logic efficient and avoid unnecessary API calls.
