morpheus-graphql v0.5.0 Release Notes

Release Date: 2019-10-31 // over 4 years ago

  • ➕ Added

    • 📜 dummy support of directives, only parsing not actual implementation

    🛠 Fixed

    • 📜 can be parsed implements with multiple interfaces separated by &
    • 0️⃣ 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
