While one can really take advantage of most play features while building a full application from scratch using play, it's very easy to drop play into existing sbt/maven projects and with just a little work use it as a REST/HTTP library. Below you can see how to do that.
A Global
object extending GlobalSettings
in the global name space is the key wiring point. GlobalSettings has a method def onRouteRequest(request: RequestHeader): Option[Handler]
that's handling play's routing.
One could easily provide an alternative implementation and start using play as a REST library!
See this for an example.
