morpheus-graphql-0.14.0

morpheus-graphql

new features

• query validation supports interfaces
• debugInterpreter: displays internal context on grahql errors
• compileTimeSchemaValidation :
  morpheus validates schema at runtime (after the schema derivation).
  to be ensure that only correct api is compiled.
  we can use template haskell method compileTimeSchemaValidation

import Morpheus.Graphql.Server(compileTimeSchemaValidation)

_validateSchema :: ()
_validateSchema = $(compileTimeSchemaValidation (Identity gqlRoot))

• directive Validation for Document (TypeSystem).

• supports of block string values. e.g:

  query {
    createDeity(
      name: """
      powerqwe
      bla \n sd
      blu \\ dete
      """
    ) {
      name
    }
  }

• Data.Morpheus.Document exposes RootResolverConstraint

• Data.Morpheus.Server exposes httpPlayground

• httpPubApp supports GQLRequest -> GQLResponse

• morpheus-graphql-core support of schema. issue #412

  schema {
    query: Query
  }

  note that this does not affect morpheus-graphql-server at all. since it has its own schema derivation. you still need to provide:

  rootResolver :: RootResolver () IO Query Undefined Undefined
  rootResolver = RootResolver <resolvers ...>

• Subscription Resolver supports Monad.

• nested Subscription Resolvers.

Breaking Changes

• Context' renamed toResolverContext'
• internal refactoring: changed AST
• root subscribtion fields must be wrapped with SubscriptionField. e.g:

data Subscription (m :: * -> *) = Subscription
{ newDeity :: SubscriptionField (m Deity),
  newHuman :: HumanArgs -> SubscriptionField (m Human)
}
deriving (Generic)

• signature of subscribe is changed. now you can use it as followed:

resolveNewAdress :: SubscriptionField (ResolverS EVENT IO Address)
resolveNewAdress = subscribe ADDRESS $ do
    -- executed only once
    -- immediate response on failures
    requireAuthorized
    pure $ \(Event _ content) -> do
        -- exectues on every event
        lift (getDBAddress content)

• removed from Data.Morpheus.Types
  • SubField
  • ComposedSubField

morpheus-graphql-client

new features

• supports interfaces.

• supports of block string values.

• support of schema. issue #412

  schema {
    query: MyQuery
  }

• generated types have instance of class Eq

breaking changes

• custom scalars Should Provide instance of class Eq

0.13.0 - 22.06.2020

morpheus-graphql-core

new features

• query validation supports interfaces

• exposed: Data.Morpheus.Types.SelectionTree

• configurable api: Data.Morpheus.Core exports

  • Config
  • defaultConfig
  • debugConfig

• for better debuging, internal errors messages will display resolving state:

  • current TypeName
  • current Selection
  • OperationDefinition
  • SchemaDefinition

• rendering graphql "AST". e.g render ( slection :: Selection VALID) will render

{
  user(arg1: 1) {
    name
  }
}

• quasiqouter [dsl| <type definitions> |] generates Schema VALID.
• parser supports custom directive definition. e.g

directive @MyDirective on FIELD_DEFINITION | OBJECT

• directive Validation for Document (TypeSystem).

• supports of block string values. e.g:

  query {
    createDeity(
      name: """
      powerqwe
      bla \n sd
      blu \\ dete
      """
    ) {
      name
    }
  }

• support of schema. issue #412

  schema {
    query: MyQuery
  }

Breaking Changes

• Context' renamed toResolverContext'
• removed : EventCon from Data.Morpheus.Core
• internal refactoring: changed AST.
  Schema AST Types now need parameter stage = RAW | CONST | VALID.
  • Schema VALID
  • TypeDefinition VALID
  • FieldDefinition IN VALID
  • ...
• runApi requires argument config

    runApi ::
      Schema s ->
      RootResModel event m ->
      Config ->
      GQLRequest ->
      ResponseStream event m (Value VALID)
