// Step 1:
// Code generation creates helpers from a GraphQL schema
// Character.* and Queries.* here are auto-generated

// Step 2:
// Build your own queries combining those helpers
val character =
  (Character.name ~
    Character.nicknames ~
    Character.origin).mapN(CharacterView)

val query =
  Queries.character("Amos Burton") {
    character
  }

case class CharacterView(name: String, nickname: List[String], origin: Origin)

// Step 3:
// Turn the query into an sttp request and run it with the sttp backend of your choice
// GraphQL result is already parsed and in the proper type
AsyncHttpClientZioBackend().flatMap { implicit backend =>
  val request: Task[Option[CharacterView]] = 
    query.toRequest(uri).send().map(_.body).absolve
