What are the best practices for using guards in Vue.js?

When using guards in Vue.js, it's important to keep your logic simple and maintainable. Use route-level guards for authentication and authorization.

Can you explain the difference between beforeEnter and beforeRouteEnter?

Sure! beforeEnter is a route guard that runs before the route is confirmed, while beforeRouteEnter runs before the route is entered, allowing access to the component instance.

How can I handle asynchronous operations in guards?

You can return a Promise in your guard to handle asynchronous operations. This allows you to wait for the operation to complete before proceeding.

What should I avoid when using guards?

Avoid complex logic in guards, as it can make your code harder to read and maintain. Keep them focused on a single responsibility.

Any tips for testing route guards?

Yes! Use unit tests to verify that your guards behave as expected under different scenarios, such as authenticated and unauthenticated users.
