What are the differences between router guards and middleware in Vue 3?

In Vue 3, router guards are specific functions that control access to routes, while middleware can be used for broader tasks like authentication or logging.

Can you give me an example of how to implement a router guard?

Sure! You can define a global guard using router.beforeEach((to, from, next) => { ... }) to check user authentication before navigating.

How does middleware fit into this? Can it be used with router guards?

Yes, middleware can be used alongside router guards to handle tasks like logging or modifying requests before they reach the guard.

Are there any performance implications of using too many guards or middleware?

Yes, excessive guards or middleware can slow down navigation, so it's important to keep them efficient and only use what's necessary.
