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".
