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

When using route guards in Vue.js, it's important to keep your logic simple and maintainable. You should also consider using named routes for better readability.

Can you explain the difference between global and per-route guards?

Global guards apply to all routes and are defined in the router configuration, while per-route guards are specific to individual routes and can be defined directly in the route's configuration.

How can I handle authentication with route guards?

You can check the user's authentication status in a beforeEnter guard. If the user is not authenticated, you can redirect them to the login page.

Are there any performance considerations I should be aware of?

Yes, avoid heavy computations in route guards as they can slow down navigation. Instead, keep them lightweight and delegate complex logic to components.

What tools can help me test my route guards?

You can use Vue Test Utils along with Jest or Mocha to write unit tests for your route guards, ensuring they behave as expected.
