Requirements
What is Node.js ?
Node.js lets you easily build networked software (websites, applications "apps" using JavaScript).
Node.js is not "point-and-click" like WordPress, SquareSpace or Salesforce.com; you will need to write some "code". But as I will demonstrate, that's a lot easier than it sounds (if you're new to writing code), gives you more power/flexibility and puts you in full control.
Frequently Asked Questions (FAQ)
Q: I am New to Programming Should I Start with Node.js?
If you have never written any code of any sort before, I recommend you starting with: http://gitbookio.gitbooks.io/javascript/ You need to have JavaScript basics to make the most of Node.js
Q: Node.js is not "Version 1.0" yet can we used it in Production?
Yes! Some of the biggest organisations/companies in the world are using Node.js in Production systems.

Node.js (Core) API
The node.js ("core") has many useful modules.
Bookmark: http://nodejs.org/api (you will come back to it)
Stability (Can we use it?)
Which node.js core package(s) can/should I use?
Every core module has a "Stability Index" rating on the node.js API.
General rule: If you are being paid to write code
that runs in node.js,
pick core modules/methods
with stability Stable, API Frozen and Locked.
Examples
- cluster is Experimental - don't use
- domain is Unstable - don't use
- path is Stable - use
- events is Frozen - use
- assert is Locked - use
