Description: The ‘Permission Guard’ in Angular is a fundamental mechanism used to control access to different routes within an application. Its main function is to verify whether a user has the necessary permissions to access a specific route before allowing them to navigate to it. This is achieved by implementing a class that implements the ‘CanActivate’ interface, which contains a method that returns a boolean value or an observable that determines whether navigation should proceed or be blocked. Permission guards are especially useful in applications that require authentication and authorization, as they allow for the protection of sensitive routes and ensure that only users with the appropriate privileges can access them. Additionally, they can be used to redirect users to login pages or other routes if they do not meet access requirements. In summary, the ‘Permission Guard’ is an essential tool in web application development for managing security and access control, ensuring that the user experience is both safe and smooth.
