mockResolve hook

The mockResolve hook, as the name indicates, can be used to mock the response of an Operation. During development, the real server might not be available, or you don't want to make a real request, e.g. a write operation to a database.

In this case, you can use the mockResolve hook to mock the response of an Operation. The actual resolver will be skipped in this case.

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
• operations: The operations client, used to call other (internal) operations
• response: The response object (only for postResolve hooks)
• input: The input object (only for Operation hooks)

With the operations client, 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.

// wundergraph.server.ts
export default configureWunderGraphServer(() => ({
  hooks: {
    queries: {
      Dragons: {
        mockResolve: async (hook) => {
          return {
            data: {
              dragons: [
                {
                  name: 'Dragon 1',
                },
              ],
            },
          };
        },
      },
    },
  },
}));
