You can do some pretty amazing things when you pair PubNub with a user interface. We jump at the chance to build awesome sample apps (plus it often lets us show off our HTML5/CSS3 chops, which we love). Now, with the launch of PubNub Channel Presence, which allows for realtime information and user detection, we were given the perfect opportunity to create a slick, completely free, open source (MIT-licensed) realtime group live HTML5 chat app.
Check out the HTML5 Chat app, download the code, and see how you can easily create powerful realtime web apps without needing to worry about the complexities around Long Polling, WebSockets, SPDY, WebRTC, and the other collection of acronyms and pseudo-standards out there. Step through this simple walkthrough to learn how to completely customize, tweak, improve, and embed PubNub’s Live Group Chat into your own apps.
