Adding Feature to Chat

Over the last couple of days, I have revisited Socket.io because I realized that I did not understand its power and coolness while I was doing the Chat-App Project. I have decided to implement a few new features, including: making it responsive, adding sounds when a user sends or receives a message, notifying that someone is typing underneath the input bar, etc.

I decided to write a tutorial on how to include the notification that someone was typing because it had some fun jQuery involved as well as a good demonstration of how sockets work in the chat application. As I have felt the most benefit from tutorials that have both video and text, I did both. The video is here and you can read the written tutorial on my blog Revisiting Sockets.
