object Comet

Helper function to produce a Comet using Akka Streams.

Please see https://en.wikipedia.org/wiki/Comet_(programming) for details of Comet.

Example:

def streamClock() = Action {
  val df: DateTimeFormatter = DateTimeFormatter.ofPattern("HH mm ss")
  val tickSource = Source.tick(0 millis, 100 millis, "TICK")
  val source = tickSource.map((tick) => df.format(ZonedDateTime.now()))
  Ok.chunked(source via Comet.flow("parent.clockChanged"))
}

  9. def flow(callbackName: String, initialChunk: ByteString = initialByteString): Flow[ByteString, ByteString, NotUsed]

    Creates a flow of ByteString.

    Creates a flow of ByteString. Useful when you have objects that are not JSON or String where you may have to do your own conversion.

    Usage example:

    val htmlStream: Source[ByteString, ByteString, NotUsed] = Flow[Html].map { html =>
  ByteString.fromString(html.toString())
}
...
Ok.chunked(htmlStream via Comet.flow("parent.clockChanged"))
