I recently wrote a GraphQL Server as part of my Multiplatform-Everything project: https://github.com/Martmists-GH/multiplatform-everything
It includes codegen for a client based on a graphqls schema file, and supports queries, mutations and subscriptions (using the graphql-transport-ws protocol).
If you want to write graphql queries while sticking closely to the syntax with proper checking, you can now just write

val me = myGraphQLClient.query {
    me {
        name
        id
        fragment on AdminUser {  // for lack of `... on AdminUser`
            capabilities
        }
    }
}
println(me.name)
if (me is AdminUser) {
    println(me.capabilities)
}

and it'll return fully typed data 🙂

As for the server, the DSL mostly inspired by KGraphQL with some small improvements where I felt it was necessary, as well as being fully suspending, supporting interface types, arguments and including error paths.

Any feedback would be much appreciated!
