What are some advanced examples of router guards in Vue 3?

In Vue 3, router guards can be used to control access to routes. Advanced examples include using guards for authentication, role-based access control, and data fetching before entering a route.

Can you explain how to implement a role-based access control guard?

Sure! You can create a global before guard that checks the user's role against the required role for a route. If the user doesn't have the required role, you can redirect them to a different page.

What about handling asynchronous data fetching in guards?

You can use async/await in your guards to fetch data before entering a route. This ensures that the necessary data is available before the component is rendered.

Are there any best practices for using router guards?

Yes, keep your guards simple, avoid heavy logic, and consider using a centralized store for user authentication state to make it easier to manage access.
