kgraphql-ktor

A simple integration for kgraphql and ktor

NOTE: this library is just a bodging for kgraphql and is not intended to be stable! I made a better library Kaguya

Introduction

I believe graphql doesn't need a plugin. Instead, it needs a routing extension just like the get and post extensions.

So, This library is just some routing extensions to handle graphql requests.

How to apply?

This is an example of using this library:

fun Route.configureGraphql() {
    route("/graphql") {
        graphqlPlayground()
        graphql {
            wrapErrors = true

            schema {
                firstSchema()
                secondSchema()
                thierdSchema()

                firstRootSchema()
                secondRootSchema()
                thierdRootSchema()
            }
        }
    }
}

Thoughts about KGraphql

KGraphQL is not a stable library to use, and I don't think the maintainers will continue supporting it. First, the original maintainer pgutkowski just archived the repository and the second maintainer aPureBase is doing nothing to upgrade it!

I think KGraphql has so many faults and bad designs. One of them is the ktor plugin with so poorly chosen technics to receive execution parameters. Another fault is the schema building technic.

I think the base builders should be more abstract with no reflection or automation. Then, adding optional reflection utilities as a syntax-sugar or whatever. But, KGraphQL just loves reflection to the degree that you cannot escape it.

Bodging should be the easiest task to be done. Since you don't need to think about any consequences. But, with KGraphQL, you cannot bodge without using some "Illegal" usage of the library like accessing private fields or implementing a class with its functions all throwing an exception just because you know the library will not invoke them.
