How do I use route guards in Vue 3?

In Vue 3, route guards are used to control access to routes. You can define them globally, per-route, or in components.

Can you show me an example of a global route guard?

Sure! You can use router.beforeEach to define a global guard. For example:

router.beforeEach((to, from, next) => {
  const isAuthenticated = // your logic here;
  if (to.meta.requiresAuth && !isAuthenticated) {
    next({ name: 'Login' });
  } else {
    next();
  }
});

What if I want to protect a specific route?

You can add a meta field to your route definition. For example:

const routes = [
  { path: '/dashboard', component: Dashboard, meta: { requiresAuth: true } }
];

How do I handle navigation failures?

You can handle navigation failures by using the next(false) method in your guard. This will cancel the navigation.
