quick demo

Enable WebSocket server bindings

Edit ccConfig.hpp set USE_WEBSOCKET_SERVER to 1

OR

Add definition in project files(VS, Xcode, Android.mk etc.) .

Edit JS code

if(typeof WebSocketServer == "undefined") {
    console.error("WebSocketServer is not enabled!");
    return;
}


let s = new WebSocketServer();
s.onconnection = function(conn) {
    conn.ondata = function(data) {
        conn.send(data, (err)=>{});
    }
    conn.onclose = function() { console.log("connection gone!");} ;
};

s.onclose = function() {
  console.log("server is closed!")
}
s.listen(8080, (err) => {
   if(!err) console.log("server booted!");
});

Thanks for quick fix! After update, we can compile success, and run app on android device. But Game crashes on startup:
