morpheus-graphql v0.7.0 Release Notes

Release Date: 2019-11-23 // over 4 years ago

  • ✂ Removed

    • toMorpheusHaskellAPi from Data.Morpheus.Document functionality will be migrated in morpheus-graphql-cli

    🔄 Changed

    • liftM to MonadTrans instance method lift

    • liftEitherM to liftEither

    • Resolver operation m event value -> Resolver operation event m value , monad trans needs that last 2 type arguments are monad and value that why it was necessary

    • 🔦 exposed Data.Morpheus.Types.Internal.AST

    • Mutation Resolver was changed from

    resolver :: () -> ResolveM EVENT IO Address
resolver = MutResolver  {
  mutEvents = [someEventForSubscription],
  mutResolver = lift setDBAddress
}

    -- Mutation Wit Event Triggering : sends events to subscription
resolver :: () -> ResolveM EVENT IO Address
resolver = MutResolver \$ do
  value <- lift setDBAddress
  pure ([someEventForSubscription], value)
-- or
-- Mutation Without Event Triggering
resolver :: () -> ResolveM EVENT IO Address
resolver _args = lift setDBAddress

    ➕ Added

    • ➕ added parseDSL to Data.Morpheus.Document

    • 👍 GraphQL SDL support fully supports descriptions: onTypes, fields , args ... with (enums, inputObjects , union, object) for example :

      """
  Description for Type Address
  """
  type Address {
    """
    Description for Field city
    """
    city: String!
    street(
      """
      Description argument id
      """
      id: ID!
    ): Int!
  }

    ###### GraphQL SDL

      type User {
    name: String! @deprecated(reason: "some reason")
  }

    will displayed in introspection

    ###### introspection.json

      {
    "data": {
      "__type": {
        "fields": [
          {
            "name": "city",
            "isDeprecated": true,
            "deprecationReason": "test deprecation field with reason"
          }
        ]
      }
    }
  }

    • 🗄 basic support of directive @deprecated on enumValue and object field, only on introspection

    • 🗄 GraphQL Client deprecation warnings

    on type

      type Human {
    humanName: String!
    lifetime: Lifetime! @deprecated(reason: "some reason")
    profession: Profession
  }

    compiler output:

      warning:
    Morpheus Client Warning:
    {
      "message":"the field \"Human.lifetime\" is deprecated. some reason",
      "locations":[{"line":24,"column":15}]
    }

    • 🆕 new helper resolver types aliases:

      • ResolveQ : for Query
      • ResolveM : for Mutation
      • ResolveS : for Subscription

    ResolveM EVENT IO Address is same as MutRes EVENT IO (Address (MutRes EVENT IO))

    is helpfull wenn you want to resolve GraphQL object

    🛠 Fixed

    • ➕ added missing Monad instance for Mutation resolver
    • defineByIntrospectionFile does not breaks if schema contains interfaces
    • 👍 Morpheus Client supports Subscription and Mutationoperations
