JSONP helper.
JSONP helper.
Example of use, provided the following route definition:
GET /my-service Application.myService(callback: String)
The following action definition:
def myService(callback: String) = Action { val json = ... Ok(Jsonp(callback, json)) }
And the following request:
GET /my-service?callback=foo
The response will have content type “text/javascript” and will look like the following:
foo({...});
Another example, showing how to serve either JSON or JSONP from the same action, according to the presence of a “callback” parameter in the query string:
def myService = Action { implicit request => val json = ... request.queryString.get("callback").flatMap(_.headOption) match { case Some(callback) => Ok(Jsonp(callback, json)) case None => Ok(json) } }

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")) }
This class provides an easy way to use Server Sent Events (SSE) as a chunked encoding, using an Akka Source.
