Changes

Changelog

see latest changes on Github

0.19.0 - 21.03.2022

Minor Changes

  • accept indexes for GraphQL Error Path (#662)
  • supports aeson 2.0

0.18.0 - 08.11.2021

  • GraphQL errors support additional field extensions :: Maybe Value
  • the parser reports invalid empty selection sets
  • The parser is compliant with the GQL specification and supports all valid characters #581
  • The parser performance improvement: on average 3-4 times faster, in some cases more than 100 times faster.

0.17.0 - 25.02.2021

New features

  • Data.Morpheus.Core provides default GrapHQL type definitions with internalSchema
  • exposed Data.Morpheus.Internal.Ext

Breaking changes

  • parseTypeSystemDefinition and parseGQLDocument is replaced with parseSchema

  • parseFullGQLDocument replaced with parseFullSchema

  • removed parseDSL from Data.Morpheus.Core

  • following Types and modules are migrated to the new package morpheus-graphql-app:

    • following types and functions in Data.Morpheus.Core are moved in to Data.Morpheus.App: App, AppData, runApp, withDebugger, mkApp, runAppStream
    • typeClass MapAPI migrated from Data.Morpheus.Types.IO is moved into Data.Morpheus.App
    • Data.Morpheus.Types.Internal.Resolving moved asData.Morpheus.App.Internal.Resolving
  • RootResModel was renamed to RootResolverValue

  • ResModel was replaced with more general ResolverValue

  • GQLScalar was replaced with EncodeScalar and DecodeScalar type-classes.

  • Value.Float is now Double instead of Float.

0.16.0 - 05.11.2020

Breaking Changes

  • signature changes:

    • render: a -> Text to a -> ByteString

    • parseTypeSystemDefinition : Text -> Eventless (Schema VALID) to ByteString -> Eventless (Schema VALID)

    • parseTypeDefinitions: Text -> Eventless [TypeDefinition ANY CONST] to ByteString -> Eventless [TypeDefinition ANY CONST]

new features

Minor Changes

  • parser performance optimization

0.15.1 - 12.09.2020

relaxed upper boundary of megaparsec up to 10.0.0

0.15.0 - 12.09.2020

new features

  • render renders SchemaDefinition e.g

    schema {
      query: MyQuery
    }
    
  • query validator automatically adds __typename to interface types

  • type : App

    api :: a -> m b
    api = runApp (mkApp schema resolvers)
    
  • App supports semigroup(schema Stitching):

    if whe have two apps app1 and app2 with type Api EVENT IO we can merge it as.

    mergedApi :: a -> m b
    mergedApi = runApp (app1 <> app2)
    
  • runApp changed signature to:

    runApp :: Api e m -> a -> m b
    

Breaking Changes

  • removed runApi.

Minor Changes

  • internal refactoring

0.14.1 - 16.08.2020

0.14.0 - 15.08.2020

new features

  • query validation supports interfaces

  • exposed: Data.Morpheus.Types.SelectionTree

  • configurable api: Data.Morpheus.Core exports

    • Config
    • defaultConfig
    • debugConfig
  • for better debugging, internal errors messages will display resolving state:

    • current TypeName
    • current Selection
    • OperationDefinition
    • SchemaDefinition
  • rendering graphql “AST”. e.g render (selection :: Selection VALID) will render

{
  user(arg1: 1) {
    name
  }
}
  • quasiquoter [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: """
        power
        bla \n sd
        blu \\ date
        """
      ) {
        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)

  • added dependency mtl
  • validates strings as enum from JSON value

0.12.0 - 21.05.2020
