morpheus-graphql-0.5.0

Added

• dummy support of directives, only parsing not actual implementation

Fixed

• can be parsed implements with multiple interfaces separated by &

• can be parsed default value on inputobject

• Parser supports anonymous Operation: query , mutation , subscription
  for example:

  mutation {
     name
  }
  

• Morpheus client does not breaks on Boolean type, converts every GraphQL type Boolean to haskell Bool and GQL String to Text

Changed

• Reduced GQLRootResolver signature :

  GQLRootResolver IO () () Query () () -> GQLRootResolver IO () Query () ()

  GQLRootResolver IO Channel Content Query Mutation Subscription -> GQLRootResolver IO APIEvent Query Mutation Subscription

  where APIEvent = Event Channel Content

• GQLRootResolver automatically assigns corresponding monad to GraphQL Types.

  you can write just:

  GQLRootResolver IO APIEvent Query  Mutation Subscription

  instead of:

  GQLRootResolver IO APIEvent (Query (Resolver IO))  (Mutation (MutResolver IO ApiEvent) (Subscription (SubResolver IO ApiEvent))

  where operations are generated by importGQLDocument or have form :

  data Query m = Query {
    field1 :: Args -> m Field1,
    ....
  }
  

• () was replaced with Undefined in GQLRootResolver for empty operations mutation, subscription

  rootResolver :: GQLRootResolver IO () Query Undefined Undefined
  

• Root Operations Query, Mutation, Subscription are passed to root resolvers without boxing inside a monad.

• there are only 3 kind of resolvers MutResolver, SubResolver , QueryResolver defined by GADT Resolver

morpheus-graphql-0.4.0

Changed

• support of Default Value:

  • on query: Parsing Validating and resolving
  • on Document: only Parsing

• lens is removed from Library, client field collision can be handled with GraphQL alias:

  {
    user {
      name
      friend {
        friendName: name
      }
    }
  }

Fixed:

• Data.Morpheus.Document.toGraphQLDocument generates only user defined types. #259

• Morpheus Client Namespaces Input Type Fields, they don't collide anymore:
  example:
  schema:

  input Person {
    name: String!
  }

  query:

  query GetUser (parent: Person!) {
    ....
  }

  wil generate:

  data GetUserArgs = GetUserArgs {
    getUserArgsParent: Person
  } deriving ...
  
  data Person = Person {
    personName: Person
  } deriving ...

• Morpheus Client Generated Output Object And Union Types don't collide:

  type Person {
    name: String!
    parent: Person!
    friend: Person!
  }

  And we select

  {
    user {
      name
      friend {
        name
      }
      parent {
        name
      }
      bestFriend: friend {
        name
        parent {
          name
        }
      }
    }
  }

  client will Generate:

  • UserPerson from {user
  • UserFriendPerson: from {user{freind
  • UserParentPerson: from {user{parent
  • UserBestFriendPerson: from {user{bestFrend
  • UserBestFriendParentPerson: from {user{bestFrend{parent

• GraphQL Client Defines enums and Input Types only once per query and they don't collide

morpheus-graphql-0.3.1

Changed

• removed dependencies: attoparsec , utf8-string
• updated aeson lower bound up to: 1.4.4.0

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 } }

morpheus-graphql-0.2.2

Fixed

• Parser Supports GraphQL multiline comments

• Morpheus GraphQL Client: Support GraphQL Alias

• Support of GraphQL Interfaces on GraphQL Document:

  # simple.gql
  interface Node {
    nodeId: ID!
  }
  
  type SimpleType implements Node {
    nodeId: ID!
    name: Text!
  }

  morpheus compiler will read interfaces and validate implements.
  template haskell will generate haskell types only for types not for interfaces.

  haskell type from simple.gql:

   data SimpleType = SimpleType {
      nodeId :: ID!
      name   :: Text!
    }  deriving (Generic)

  at the time compiler does not validates field Arguments by interface

morpheus-graphql-0.2.1

[0.2.1] - 23.08.2019

• assets are added to cabal source files to fix distribution building

morpheus-graphql-0.2.0

[0.2.0] - 23.08.2019

thank you for contributing: @horus @ryota-ka @hovind @gvolpe

Added

• Parser Supports GraphQL Single Line comments

• Enhanced Subscription: mutation can trigger subscription with arguments

• Experimental Support of Input Unions

• GraphQL schema generating with: Data.Morpheus.Document.toGraphQLDocument

• Generating dummy Morpheus Api from schema.gql:

  morpheus build schema/mythology.gql src/MythologyApi.hs
  

  details

• convertToJSONName & convertToHaskellName has been extended to support all Haskell 2010 reserved identities. details

• GraphQL Client with Template haskell QuasiQuotes (Experimental, Not fully Implemented)

  defineQuery
    [gql|
      query GetHero ($byRealm: Realm)
        {
          deity (realm:$byRealm) {
            power
            fullName
          }
        }
    |]

  will Generate:

  • response type GetHero, Deity with Lens Instances
  • input types: GetHeroArgs , Realm
  • instance for Fetch typeClass

  so that

    fetchHero :: Args GetHero -> m (Either String GetHero)
    fetchHero = fetch jsonRes args
        where
          args = GetHeroArgs {byRealm = Just Realm {owner = "Zeus", surface = Just 10}}
          jsonRes :: ByteString -> m ByteString
          jsonRes = <fetch query from server>

  resolves well typed response GetHero.

• Ability to define GQLSchema with GraphQL syntax ,
  so that with this schema

  [gqlDocument|
    type Query {
      deity (uid: Text! ) : Deity!
    }
  
    type Deity {
      name  : Text!
      power : Text
    }
  |]
  
  rootResolver :: GQLRootResolver IO () () Query () ()
  rootResolver =
    GQLRootResolver {queryResolver = return Query {deity}, mutationResolver = pure (), subscriptionResolver = pure ()}
    where
      deity DeityArgs {uid} = pure Deity {name, power}
        where
          name _ = pure "Morpheus"
          power _ = pure (Just "Shapeshifting")

  Template Haskell Generates types: Query , Deity, DeityArgs, that can be used by rootResolver

  generated types are not compatible with Mutation, Subscription,
  they can be used only in Query, but this issue will be fixed in next release

Fixed:

• Parser supports enums inside input Object

• fulfilled fragment Validation (added: unusedFragment,nameConflict)

• correct decoding of Enums with more than 3 constructor #201

• Duplicated variable names in Http requests are validated using Aeson's jsonNoDup function. So the following request will
  result in a parsing error

  {"query":"...",
  "variables":{"email":"foo@mail.net", "email":"bar@mail.net",...}}
  

Changed

• WebSocket subProtocol changed from graphql-subscriptions to graphql-ws

• type familiy KIND is moved into typeClasses GQLType, so you should replace

  type instance KIND Deity = OBJECT
  
  instance GQLType Deity where
    description  = const "Custom Description for Client Defined User Type"
  
  data Deity = Deity { fullName :: Text } deriving (Generic)

  with

  instance GQLType Deity where
  type KIND Deity = OBJECT
  description = const "Custom Description for Client Defined User Type"
  
  data Deity = Deity { fullName :: Text } deriving (Generic)

morpheus-graphql-0.1.1

Fixed:

• () as Subscription or Mutation does not defines Operator without fields

morpheus-graphql-0.1.0

thanks for contributing to: @krisajenkins, @hovind, @vmchale, @msvbg

Added

• support of haskell Types: Map, Set, and Pair (a,b)
• GraphQL Resolver supports custom Monad
• add Interpreter class with instances:
  • ByteString -> m ByteString and Lazy ByteString, where m is resolver monad
  • Text -> m Text and Lazy Text, where m is resolver monad
  • GQLRequest -> m GQLResponse , When you using it inside another Component that have Manual ToJSON deriving,
    you have to ensure that GQLResponse will be encoded with toEncoding, and not with toJSON.
• Schema Validation:
  • Name Collision
• support of Parsing input values: Objects,Arrays
• support scalar type: ID
• scalar Types are validated by GQLScalar instance function parseValue

  • SCALAR
  • OBJECT,
  • ENUM
  • INPUT_OBJECT
  • UNION
• inline Fragments
• GraphQL Aliases
• Subscriptions: GQLSubscription
  • a -> EffectM b operation: is resolver that contains side effect in EffectM.
    is used for Mutation and Subscribe communication
  • gqlEffectResolver ["CHANNEL_ID"]: packs as effect Resolver.
    if mutation and subscription resolver have same channel then
    every call of mutation will trigger subscription resolver
  • GQLState: shared state between http and websocket server
  • gqlSocketApp :converts interpreter to websocket application
  • graphql-subscriptions: Apollo GraphQL subProtocol
• language:
  • Query supports : __type(name:"type")
  • On every Object can be selected : __typename

Changed

• GQLRootResolver, GQLType(..) , GQLScalar(..)
  are moved in Data.Morpheus.Types
• GQLRoot { query, mutation, subscription } to GQLRootResolver {queryResolver, mutationResolver, subscriptionResolver}
• interpreter: can be used in http and websocket server
• GQLKind renamed as GQLType
• types can be derived just with (Generic,GQLType)
• haskell record field type' will generate GQL Object field type
• public API (all other modules are hidden):
  • Data.Morpheus
  • Data.Morpheus.Kind
  • Data.Morpheus.Types
  • Data.Morpheus.Server

Fixed:

• parser can read fields with digits like: a1 , _1
• you can use Wrapped type and Wrapped Primitive Types issue #136:
  • wrapped TypesNames will be separated with "_" : typeName(Either A B) -> "Either_A_B"
• introspection:
  • argument supports Non-Null and List
  • every field has correct kind

Removed

• GQLArgs: you can derive arguments just with Generic without GQLArgs
• GQLObject: replaced with instance type instance KIND <Type> = OBJECT
• GQLEnum: replaced with instance type instance KIND <Type> = ENUM
• GQLInput: replaced with instance type instance KIND <Type> = INPUT_OBJECT
• Typeable : with new deriving it is not required anymore
• Wrapper: with TypeFamilies there is no need for Wrapper
• a ::-> b is Replaced by a -> ResM b where ResM is alias for Resolver IO a
• GQLMutation , GQLQuery : with new deriving it is not required anymore
• Resolver constructor replaced by functions:
  • gqlResolver : packs m Either String a to Resolver m a
  • gqlEffectResolver: resolver constructor for effectedResolver
  • liftEffectResolver: lifts normal resolver to Effect Resolver.
