Our company has “hack-off” days once a while, where we developers get to choose whatever we would like to work on and present it to the entire company by the end of the day. I have been hearing this websocket buzz for a while now and would like to build something interesting with it. WebSocket Websocket is a persistent bi-directional connection between the browser and the server. With websocket, web browser can post message to the server, but what’s more interesting is that the server is able to push messages to the client (browser).
