Prowlgria is a scala GraphQL library, with some custom code specifically written for Prowl.
SBT Configuration:
libraryDependencies += "org.sangria-graphql" %% "sangria" % "1.0.0-RC5"
You can find an example application that uses akka-http with sangria here:
https://github.com/sangria-graphql/sangria-akka-http-example
More info and the documentation can be found in the project home page:
I would also would recommend you to check out http://try.sangria-graphql.org. It is an example of GraphQL server written with Play framework and Sangria. It also serves as a playground, where you can interactively execute GraphQL queries and play with some examples.
If you want to use sangria with react-relay framework, then you also may be interested in sangria-relay.
