morpheus-graphql-0.3.0

Added

• user can import GraphQL Document and generate types with it.

    importGQLDocument "API.gql"

  this will generate types defined in API.gql

Fixed

• String defined in GQLDcoument will be converted to Text by template haskell

• importGQLDocument and gqlDocument supports Mutation, Subscription and Resolvers with custom Monad

  for example. if we have:

  type Deity {
    name: String!
    power: Power!
  }

  where Power is another object defined by gql schema.
  template haskell will represent this type as:

     data Deity m = Deity {
       name :: () -> m Text,
       power :: () -> m (Power m)
     }

  where m is resolver Monad.

• importGQLDocumentWithNamespace generates namespaced haskell records. so that you have no more problem with name collision.
  from this gql type:

  type Deity {
    name: (id:Int)String!
    power: Power!
  }

  will be generated.

  data Deity m = Deity {
    deityName :: DeityNameArgs -> m Text,
    deityPower :: () -> m (Power m)
  }
  
  data DeityNameArgs = DeityNameArgs {
    deityNameArgsId :: Int
  }

Changed

• GQLType is mandatory for every GQL Type (including Query, Mutation and Subscription)

• subscription Resolver changed

  from:

    Subscription {newDeity = \args -> Event {channels = [ChannelA], content = newDeityResolver } }

  to:

    Subscription {newDeity = \args -> SubResolver {subChannels = [ChannelA], subResolver = newDeityResolver } }
