What are the best practices for using Angular router guards?

The best practices for using Angular router guards include keeping them simple, using them for authentication and authorization, and ensuring they are reusable.

Can you explain how to implement an authentication guard?

To implement an authentication guard, create a service that implements the CanActivate interface, then use it in your routing module.

What are the differences between CanActivate and CanDeactivate?

CanActivate checks if a route can be activated, while CanDeactivate checks if a user can leave a route.

How can I handle multiple guards for a single route?

You can handle multiple guards by providing an array of guards in the route configuration, and all must return true for the route to activate.

Are there any performance considerations I should be aware of?

Yes, avoid heavy computations in guards, as they can slow down navigation. Use observables efficiently to manage asynchronous checks.
