For now this only provides the data types to represent the GraphQL AST, but the idea is to be a Haskell port of graphql-js. Next releases should include:

• GraphQL AST
• Parser for the GraphQL language. See TODO for limitations.
• Printer for GraphQL. This is not pretty yet.
• GraphQL Schema AST.
• Parser for the GraphQL Schema language.
• Printer for the GraphQL Schema language.
• Interpreter of GraphQL requests.
• Utilities to define GraphQL types and schema.

See the TODO file for more concrete tasks.

Suggestions, contributions and bug reports are welcome.

Feel free to contact on Slack in #haskell on GraphQL. You can obtain an invitation here.
