How could i manage to add or remove field from a GraphQL query

Hi, I'm currently looking on how i could be able to add / remove fields from a query either be a directive (using KotlinSchemaDirectiveWiring).

Is there an easy way i could adjust the fields a user is querying on an object, the fields are parts of the object definitions, it's only to figure out how i could add them to the query

It would be use at some point to adjust some informations the client is requesting.

Thanks

No it is not possible. If a user requests fieldA then they are guaranteed to get fieldA (or null if it is nullable) in the response OR its a server error. Changing request to remove some fields/add additional fields is breaking the contract (and will break your clients).

You could use directives to apply some authentication mechanism to modify the response to return null for unauthenticated/unauthorized users but your response would still contain an entry for the given field.
