This is a simple video screen cast on how to build a simple chat system for an existing website served by an existing web server by adding another NodeJS powered Socket.IO server for asynchronous updates all working on Windows. In this example a plain HTML file is programmed with simple Javascript to communicate with a Socket.IO server powered by NodeJS. The HTML file is hosted on a traditional Apache Server (WAMP) showing. The communication between the client JavaScript and Socket.IO is Asynchronous, and there's not much AJAX in the code because it's all covered by Socket.IO. To improve the setup, the HTML file could be a PHP, Python, or Ruby generated page of an existing website. We can observe how easy it is to add a chat system for such website with very minimal coding necessary. You can find more details from this Google Code Project: code.google.com Thank you for watching the video.
