This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

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.

Secure private web server with NodeJS

This article will explain how to set up a secure web server with NodeJS which only accepts connection from users with SSL certificates that you have signed. This is an efficient way to ensure that no other people are able to access the web server, without building a login system which will be significantly weaker.

I will not explain how to create a certificate authority (CA), create certificates or sign them. If you need to read up on this, have a look at this excelent article on how to do it with OpenSSL (Mac and Linux): https://help.ubuntu.com/community/OpenSSL#Practical_OpenSSL_Usage It is also possible to do this on a Mac with the keychain application, and I assume it is possible on a Windows machine aswell.

This architecture will allow you to have one web server communicating with an array of trusted clients, the web server itself can be on the public internet, that will not decrease the level of security, but it will only ser
