Getting Started

FIRST EXAMPLE

Client (HTML)

<script src="/socket.io/socket.io.js"></script>
<script>
        var socket = io.connect('http://localhost:9090');
        socket.on('news', function (data) {
            console.log(data);
            socket.emit('my event', data+' new');
        });
</script>

Client (GWT)

ScriptInjector.fromUrl("/socket.io/socket.io.js").setCallback(new Callback<Void, Exception>() {

		@Override
		public void onSuccess(Void result ) {
			// TODO Auto-generated method stub
			final TJSocketIO socket=TJSocketIO.connect("http://localhost:9090");
            socket.onSocket("news",new SocketHandler<String>() {

				@Override
				public void onSocket(String data ) {
					// TODO Auto-generated method stub
					GWT.log(data);
					socket.emitSocket("my event",data+" new");
				}
			});
		}

		@Override
		public void onFailure(Exception reason) {
			// TODO Auto-generated method stub
			
		}
		
}).inject();

SECOND EXAMPLE

Client (HTML)

<script>
        socket.on('connect', function () {
           
            socket.emit('my event','hello jumanor',function(data){
                
                console.log(data);
                
            });
        });
</script>

Client (GWT)

socket.onSocket("connect", new SocketHandler<Void>() {

	@Override
	public void onSocket(Void data) {
	// TODO Auto-generated method stub
					
		socket.emitSocketResponse("my event", "hello jumanor", new SocketHandler<String>() {

            @Override
            public void onSocket(String data) {
                // TODO Auto-generated method stub
                GWT.log(data);                    
            }
						
		});
    }
				
});

THIRD EXAMPLE

Client (HTML)

<script>
        socket.on('my event', function (data,response) {
           
            var resp={};
            resp.data=data;
            
            response(resp);
        });
</script>

Client (GWT)

socket.onSocket("my event",new SocketAndResponseHandler<String,JavaScriptObject>() {

	@Override
	public void onSocketAndResponse(String data,ResponseHandler<JavaScriptObject> respuesta) {
		// TODO Auto-generated method stub
					
		JSONObject resp=new JSONObject();
		resp.put("data", new JSONString(data));
					
		respuesta.onResponse(resp.getJavaScriptObject());
					
	}
});
