How do I handle async operations in Vue 3 router guards?

In Vue 3, you can handle async operations in router guards by returning a Promise. This allows you to wait for async tasks to complete before navigating.

Can you give me an example of that?

Sure! In your router configuration, you can define a beforeEnter guard like this:

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

What if I need to handle multiple async operations?

You can use Promise.all to handle multiple async operations. Just ensure that you wait for all promises to resolve before calling next().
