Guards

Guards control access to routes within an application. They allow you to define navigation rules based on the user's status (authenticated or not), permissions, and route definitions.

Registering and Unregistering Guards

Guards are registered and unregistered in the boot/kdk.js file.

Registering

To register a guard, use the registerGuard method :

beforeGuard.registerGuard(authenticationGuard)
beforeGuard.registerGuard(routeGuard)

Unregistering

To unregister a guard, use the unregisterGuard method :

beforeGuard.unregisterGuard(authenticationGuard)
beforeGuard.unregisterGuard(routeGuard)

Authentication Guard

The authenticationGuard function uses the metadata (authenticated, unauthenticated or public) defined in the routes to check if a user is authenticated and whether to allow navigation.

Permissions Guard

The permissionsGuard function checks if the user has the necessary permissions to access a route. Permissions can be defined in the route's metadata (can) and may use route or query parameters.

Route Guard

The routeGuard checks if the corresponding route is valid.

TIP

routeGuard should be defined after authenticationGuard.
