WAMP implementation for the Play! Framework

About

This is a WAMP implementation for the Play! Framework. Use it to add RPC and Pub/Sub websocket functionality to your site!

Getting Started

Build.scala

First add WAMPlay to appDependencies in the Build.scala file:

"ws.wamplay" %% "wamplay" % "0.1.6"

Then add the WAMPlay repo in the same file:

val main = play.Project(appName, appVersion, appDependencies).settings(
  resolvers ++= Seq("WAMPlay Repository" at "http://blopker.github.com/maven-repo/")
)

routes

Add a WAMP endpoint to your routes file:

# Send websocket connections to the WAMPlay server
GET     /wamp                     ws.wamplay.controllers.WAMPlayServer.connect()

WAMPlayController

Create a class that extends WAMPlayController. This is where your application will interact with clients. For more information on the annotations check out Annotations.

@URIPrefix("http://example.com/sample")
public class SampleController extends WAMPlayContoller {

	@onRPC("#meaningOfLife")
	public static String getMeaningOfLife(String sessionID) {
		return "Meaning of life is: 42";
	}

	@onRPC("#capital")
	public static String add(String sessionID, JsonNode[] args) {
		String ans = args[0].asText().toUpperCase();
		return ans;
	}

	@onSubscribe("/chat")
	public static boolean capitalSubscribe(String sessionID) {
		return true;
	}

	@onPublish("/chat")
	public static JsonNode truncatePublish(String sessionID, JsonNode event) {
		return Json.toJson(event);
	}
}

Global.java

In your Global.java file override onStart and add your controller to the WAMPlayServer.

public class Global extends GlobalSettings {
	@Override
	public void onStart(Application app) {
		WAMPlayServer.addController(new SampleController());
	}
}

Your server is ready!
