Writing node modules with voxel.js

This is a short guide that will teach you the workflows that have been figured out by the voxel.js community for writing node modules + sharing them on NPM and Github. It is assumed that you have a basic understanding of JavaScript, github and the command line (if not you can check out an introduction to git and the command line or learn JS basics from JavaScript for Cats)

The voxel-tower repository on github contains all the example code from this guide.

21:57 < dook> You seem to be new to node, is that right?

21:57 < skidz> good to know... yes.. very

21:57 < skidz> but familar with JS but mostly a C# programmer

21:58 < dook> Ok so the basic premise is that to make Chrome run javascript fast, they made a JS->C++ compiler called V8

21:58 < dook> It makes JS compile into very fast, efficient code.
