AshGraphql provides two json types that may be used. They are the same except for how the type is serialized in responses.

  • :json_string - serializes the json to a string, e.g "{\"foo\":1}"
  • :json - leaves the json as an object, e.g {foo: 1}

By default, :json_string is used. The configuration for this is (uncharacteristically) placed in application config, for example:

config :ash_graphql, :json_type, :json
