Modifying the Resolution

Using the modify_resolution option, you can alter the Absinthe.Resolution.

modify_resolution is an MFA that will be called with the resolution, the query, and the result of the action as the first three arguments. Must return a new Absinthe.Resolution.

This can be used to implement things like setting cookies based on resource actions. A method of using resolution context for that is documented in Absinthe.Plug

as_mutation? {: .warning}

If you are modifying the context in a query, then you should also set as_mutation? to true and represent this in your graphql as a mutation. See as_mutation? for more.
