Json API

For example:

import play.api.libs.json._
import play.api.libs.functional.syntax._

case class User(id: Long, name: String, friends: Seq[User] = Seq.empty)
object User {

  // In this format, an undefined friends property is mapped to an empty list
  implicit val format: Format[User] = (
    (__ \ "id").format[Long] and
    (__ \ "name").format[String] and
    (__ \ "friends").lazyFormatNullable(implicitly[Format[Seq[User]]])
      .inmap[Seq[User]](_ getOrElse Seq.empty, Some(_))
  )(User.apply, unlift(User.unapply))
}

object MyController extends play.api.mvc.Controller {
