How can I use async data with Vue Router?

You can use async data in Vue Router by leveraging the beforeEnter navigation guard or using route components with async setup.

Can you give me an example of using async data in a route?

Sure! You can define a route like this:

const routes = [
  {
    path: '/user/:id',
    component: User,
    async beforeEnter(to, from, next) {
      const userData = await fetchUserData(to.params.id);
      to.params.userData = userData;
      next();
    }
  }
];

What if I need to handle errors while fetching data?

You can handle errors by using a try-catch block in your async function. If an error occurs, you can redirect or show an error message.

Is there a way to show a loading state while data is being fetched?

Yes, you can use a loading state in your component. Set a loading variable to true before fetching data and set it to false once the data is ready.
