Installing Node and Express on Mac OS X

Update: Use the Mac OS X installer available at nodejs.org

And of course, you want Express to give your application a kick-start:

npm install express

And if you want to do DOM manipulation on the server-side:

npm install jquery

Enjoy. If you don’t know what these things are, here are the links: Node, NPM, Express, jQuery

In a nutshell — a whole lot of event-driven JavaScript awesome on the server side.
