How do I implement dynamic routes in Vue 3?

To implement dynamic routes in Vue 3, you can use the Vue Router. Define your routes with a dynamic segment using a colon, like this: { path: '/user/:id', component: User }.

Can you show me an example of how to fetch data for a dynamic route?

Sure! In your User component, you can use the beforeRouteEnter navigation guard to fetch data based on the id parameter. Here's a sample code snippet:

beforeRouteEnter(to, from, next) {
  fetch(`https://api.example.com/users/${to.params.id}`)
    .then(response => response.json())
    .then(data => next(vm => vm.setUser(data)));
}

What if I want to handle 404 errors for dynamic routes?

You can create a catch-all route at the end of your routes array to handle 404 errors. For example:

{ path: '*', component: NotFound } 
``` This will redirect users to a NotFound component if they navigate to an undefined route.
