Very simple #ServerSentEvent (#SSE) example

Application.scala

package controllers
 
import play.api.mvc._
import play.api.libs.EventSource
import play.api.libs.iteratee._
 
object Application extends Controller {
 
  val events = Enumerator.repeat("0")
 
  def index = Action {
    Ok.stream((events &> Enumeratee.take(10) &> EventSource()) >>> Enumerator.eof)
  }
 
}
