<p>Node is the web developers&#39; operating system. (No, <a href="https://github.com/NodeOS/NodeOS">really</a>).</p>

<p>It allows you to build anything using javascript.</p>

<p>Setting up node is the most difficult part of getting started with node.</p>

<p><a href="https://github.com/joyent/node/wiki/Installation">Follow this tutorial to set up node and npm</a>.</p>

<p>A word of caution: Do not install node from Ubuntu/Debian official repository. It will give you all sorts of trouble later on upgrading and stuff.</p>

<p>I do not remember how I installed the stuff, but the ideal installation will let you update npm packages without sudo. This will involve placing NODE_PATH in ~/.bashrc and I am sure you can find out how to do that on your own.</p>

<p>But once you have node and npm correctly installed, installing any node app globally will be like <code>$ npm install -g appname</code> and won&#39;t require <code>sudo</code></p>

<p>Node.js <a href="http://blog.izs.me/post/48281998870/unix-philosophy-and-node-js">goes well with Unix philosophy</a></p>
