How do I implement advanced navigation guards in Vue 3?

In Vue 3, you can implement advanced navigation guards by using the beforeEach, beforeEnter, and afterEach hooks in your router configuration. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a basic example:

const router = createRouter({
  history: createWebHistory(),
  routes: [
    {
      path: '/protected',
      component: ProtectedComponent,
      beforeEnter: (to, from, next) => {
        const isAuthenticated = checkAuth();
        if (isAuthenticated) {
          next();
        } else {
          next('/login');
        }
      }
    }
  ]
});

This code checks if the user is authenticated before entering the protected route.

What if I want to add a global guard?

You can add a global guard using router.beforeEach. Here's how:

router.beforeEach((to, from, next) => {
  console.log('Navigating to:', to.path);
  next();
});

This will log the path of every route the user navigates to.
