Modifying the Resolution
Using the modify_resolution
option, you can alter the Absinthe resolution.
modify_resoltion
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 here: https://hexdocs.pm/absinthe_plug/Absinthe.Plug.html#module-before-send
Important 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.
