Hi, Source.queue seems perfect to push elements dynamically into a source.
I am using Akka Streams 2.0 with Play framework (2.5-M2). In Play 2.5, the controller's 'chunked' method can take an Akka Streams Source to stream elements to the browser. In other words Play defines its own Sink and I can't run a sourceQueue into a Sink by myself. So I've tried this to create a dynamic source : val (queue, pub) = Source.queue[String](10, OverflowStrategy.fail).toMat(Sink.asPublisher(false))(Keep.both).run() val tick = Source.tick(0 second, 1 second, "tick") tick.runForeach(t => queue.offer("tick")) Ok.chunked(Source.fromPublisher(pub)) Sink.asPublisher is the only way I've found to materialize the source and keep a reference to it. But I find this a little verbose more important, it's not working, the browser is loading forever and no element is emitted. So is there a proper way to retrieve a source from Source.queue? Thanks a lot Loïc -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
