morpheus-graphql v0.3.0 Release Notes

Release Date: 2019-10-04 // over 4 years ago

  • ➕ 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 } }
