Returning resolvers from other resolvers isn't supported anymore. Since we have a type system now, we define the resolvers in the object type fields and pass an object with the previous result to them.
Haskell GraphQL
GraphQL implementation in Haskell.
This implementation is relatively low-level by design, it doesn't provide any mappings between the GraphQL types and Haskell's type system and avoids compile-time magic. It focuses on flexibility instead, so other solutions can be built on top of it.
State of the work
For now this only provides a parser and a printer for the GraphQL query
language and allows to execute queries and mutations without the schema
validation step. But the idea is to be a Haskell port of
graphql-js.
For the list of currently missing features see issues marked as "not implemented".
