Welcome

- [Emmanuel] Have you heard about this strange JavaScript and real-time library called Socket.IO, but don't quite understand its purpose? Do you dream of building your own real-time web application but don't know where to start? If you've answered yes to any of the above questions, you've come to the right place. Hi, I'm Enne Henri and I've been working with Node and JavaScript for a very long time and it is my great pleasure to help you learn about this great real-time web library called Socket.IO.

In this course we'll explore the basics of Socket.IO and build a chat application with multiple rooms. First, we'll create a base node server with Express and Socket.IO. Then we'll go through the basics of events, sockets, and continue building our chat application with these concepts. Next we'll introduce a namespace for our rooms, letting us build multiple room for users to join. So if you're ready to build your own chat application, fire up your favorite editor and let's get started.
