What are Angular routing guards and how do I use them?

Angular routing guards are interfaces that allow you to control access to routes in your application. They can be used to prevent unauthorized access, manage user permissions, or prompt users to save changes before navigating away.

Can you explain the different types of routing guards?

Sure! There are four main types of routing guards in Angular: CanActivate, CanActivateChild, CanDeactivate, and Resolve. Each serves a different purpose in route management.

How do I implement a CanActivate guard?

To implement a CanActivate guard, you need to create a service that implements the CanActivate interface, then provide it in your routing module. You can then attach it to specific routes.

What if I want to protect multiple routes with the same guard?

You can apply the same guard to multiple routes by adding it to the 'canActivate' array in the route configuration for each route you want to protect.
