Konrad, Thanks for the reply! In fact I have the very same code separation:
*object ApiJsonProtocol extends ApiJsonProtocoltrait ApiJsonProtocol extends SprayJsonSupport with DefaultJsonProtocol { implicit val feedFormat = jsonFormat2(Feed) // implicit val feedsWriter = seqFormat[Feed]}* *class FeedRoute(feedRepository: FeedRepository) extends ApiRoute with ApiJsonProtocol {* * override val underlying: Route = {* * pathPrefix("feeds") {* *pathEndOrSingleSlash {* *get {* *parameters('from.as[Int] ? 0, 'limit.as[Int] ? 10, 'title ? "") { (from, limit, title) =>* *complete(* *// TODO use (from, limit, title)* *feedRepository.findAll()* *)* *}* *}* *}* * }* *}* *}* But without the extra "*implicit val feedsWriter = seqFormat[Feed]*" it does not compile. On GitHub I've found several examples of people trying to solve the same problem: 1) Use of .toJson before wrapping into complete(...) https://github.com/ArchDev/akka-http-rest/blob/master/src/main/scala/me/archdev/restapi/http/routes/UsersServiceRoute.scala 2) Declaring implicit val for each Seq[of somethings] but in this particular case the author went further and coded full RootJsonWriter https://github.com/dit4c/dit4c/blob/f66f833ef35d58234391e9e0f09ad36b7a4a6206/dit4c-machineshop/src/main/scala/dit4c/machineshop/ApiService.scala So, it appears I'm not the only one who finds this a little bit confusing.
