What are route guards in Vue 3?

Route guards in Vue 3 are functions that control access to routes based on certain conditions.

How do I implement a route guard?

You can implement a route guard by defining it in your router configuration using 'beforeEnter' or global guards.

Can you give me an example of a route guard?

Sure! Here's a simple example:

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