What are route guards in Angular and can you provide examples?

Route guards in Angular are interfaces that allow you to control access to routes based on certain conditions. For example, you can use a guard to prevent unauthorized users from accessing a route.

Can you give me a specific example of a route guard?

Sure! A common example is the CanActivate guard, which checks if a user is logged in before allowing access to a route. If the user is not logged in, they can be redirected to a login page.

How do I implement a CanActivate guard?

To implement a CanActivate guard, you create a service that implements the CanActivate interface, then define the logic to check user authentication. Finally, you add the guard to your route configuration.

What other types of route guards are there?

Other types include CanDeactivate, which checks if a user can leave a route, and Resolve, which fetches data before the route is activated.
