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

When using routing guards in Vue.js, it's important to keep your logic simple and maintainable. You should also ensure that guards are only applied where necessary to avoid performance issues.

Can you give me an example of a common use case for routing guards?

Sure! A common use case is to protect routes that require authentication. You can use a beforeEach guard to check if a user is logged in before allowing access to certain routes.

How can I handle asynchronous operations in routing guards?

You can return a Promise from your routing guard. This allows you to perform asynchronous checks, like fetching user data or verifying tokens, before resolving the route.

What should I avoid when implementing routing guards?

Avoid complex logic within your guards. Keep them focused on a single responsibility, and consider using Vuex for state management to simplify your guards.
