morpheus-graphql v0.9.2 Release Notes

  • 💥 Breaking Changes

    • all constructors of Resolver: QueryResolver,MutResolver,SubResolver are unexposed. use lift , publish or subscribe. e.g
      -- Query Resolver
  resolveUser :: ResolveQ EVENT IO User
  resolveUser = lift getDBUser

  -- Mutation Resolver
  resolveCreateUser :: ResolveM EVENT IO User
  resolveCreateUser = do
    publish [userUpdate] -- publishes event inside mutation
    lift setDBUser

  -- Subscription Resolver
  resolveNewUser :: ResolveS EVENT IO User
  resolveNewUser = subscribe [USER] $ do
    pure $ \(Event _ content) -> lift (getDBUserByContent content)

    🆕 New features

    • 🔦 exposed publish for mutation resolvers, now you can write
      resolveCreateUser :: ResolveM EVENT IO User
  resolveCreateUser = do
      requireAuthorized
      publish [userUpdate]
      liftEither setDBUser
    • 🔦 exposed subscribe for subscription resolvers, now you can write
      resolveNewUser :: ResolveS EVENT IO User
  resolveNewUser = subscribe [USER] $ do
      requireAuthorized
      pure userByEvent
    where userByEvent (Event _ content) = liftEither (getDBUser content)
