Ktor

Add apollo-execution-ktor to your project

To use the Ktor integration, add apollo-execution-ktor to your dependencies and a Ktor engine:

dependencies {
  // Add the runtime dependency
  implementation("com.apollographql.execution:apollo-execution-ktor:0.1.0")
  // This sample uses netty as an engine.
  // See https://ktor.io/ for other choices.
  implementation("io.ktor:ktor-server-netty:3.0.0")
}

apollo-execution-ktor provides 3 modules:

apolloModule(ExecutableSchema) adds the main /graphql route for queries/mutations.
apolloSubscriptionModule(ExecutableSchema) adds the /subscription route for subscriptions.
apolloSandboxModule(ExecutableSchema) adds the /sandbox/index.html for the online IDE

embeddedServer(Netty, port = 8080) {
  val executableSchema = ServiceExecutableSchemaBuilder().build()
  // /graphql route
  apolloModule(executableSchema)
  // /subscription route
  apolloSubscriptionModule(executableSchema)
  // /sandbox/index.html route
  apolloSandboxModule()
}.start(wait = true)
