Post Resolve Hook

The postResolve hook is called after the response of an Operation has been resolved. Contrary to the mutatingPostResolve hook, it's not possible to manipulate the response with this hook.

The purpose of this hook is e.g. logging.

Similar to all other hooks, the customResolve hook is called with the following parameters:

  • user: The user object when the user is authenticated
  • clientRequest: The original client request object, including Headers
  • log: The logger object
  • internalClient: The internal client object
  • response: The response object (only for postResolve hooks)
  • input: The input object (only for Operation hooks)

With the internalClient, you're able to securely call into all defined Operations, e.g. to talk to a database or another service to enrich a response or manipulate the inputs of an Operation.
