Since the transform tree can already find some errors, it may fail here and there. Almost all functions return a Maybe to signalize an error. Will be replaced with an Either of course.
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".
Documentation
API documentation is available through hackage.
You'll also find a small tutorial with some examples under docs/tutorial.
Contact
Suggestions, contributions and bug reports are welcome.
Should you have questions on usage, please open an issue and ask – this helps to write useful documentation.
Feel free to contact on Slack in #haskell on GraphQL. You can obtain an invitation here.
