GraphQL Powered by Kotlin
summary
A Kotlin GraphQL stack that actually runs: a Ktor server wired with Koin and KGraphQL (plus a DB layer) exposes a single endpoint /graphql and serves an introspective schema; example data set shows 80,201 US UFO sightings and queries return only requested fields. An Android client uses Apollo Android (schema JSON + .graphql files) which generates Java models and parsers and integrates with architecture components; a simple app reads and creates sightings so the setup works end to end, though some Kotlin libraries aren’t yet marked production-ready.
