Data.GraphQL.Monad

Defines the GraphQLQueryT monad transformer, which implements MonadGraphQLQuery to allow querying GraphQL APIs.

Documentation

module Data.GraphQL.Monad.Class

data GraphQLQueryT m a

The monad transformer type that should be used to run GraphQL queries.

newtype MyMonad a = MyMonad { unMyMonad :: GraphQLQueryT IO a }

runMyMonad :: MyMonad a -> IO a
runMyMonad = runGraphQLQueryT graphQLSettings . unMyMonad
  where
    graphQLSettings = defaultGraphQLSettings
      { url = "https://api.github.com/graphql"
      , modifyReq = \req -> req
          { requestHeaders =
              (hAuthorization, "bearer my_github_token") : requestHeaders req
          }
      }
