Apollo kotlin server

[ronjunevaldoz]

Use case

Kotlin based graphql server. There are some existing kotlin server libraries:

• https://github.com/apurebase/kgraphql/ (Pure kotlin and declarative)
• https://github.com/ExpediaGroup/graphql-kotlin (Adaptation of graphql java, not declarative)

Describe the solution you'd like

If I were to choose, I would choose the approach of kgraphql due to it's best suited for pure and declarative, the only problem is kgraphql maintainers are lacking and seems to be abandoned by the original owner while expedia graph-kotlin is an active community.

feature must support the following

• pure kotlin
• declarative like kgraphql
• able to install ktor plugins (version 3.x.x if possible)
• less boilerplate
• easy to add queries, mutations, subscriptions

data class Article(val id: Int, val text: String)

fun main() {
    val schema = KGraphQL.schema {
        query("article") {
            resolver { id: Int?, text: String ->
                Article(id ?: -1, text)
            }
        }
        type<Article> {
            property<String>("fullText") {
                resolver { article: Article ->
                    "${article.id}: ${article.text}"
                }
            }
        }
    }

    schema.execute("""
        {
            article(id: 5, text: "Hello World") {
                id
                fullText
            }
        }
    """.trimIndent()).let(::println)
}

Please leave a comment about this feature requests. I would love to help to build this library.
