Async.js
Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with node.js, it can also be used directly in the browser.
nodeunit
If you're looking for a full-featured and descriptive specification framework you might want to checkout a project like the excellent jspec. If, like me, you just want to dive into writing some code and don't want to learn an extensive framework before writing tests, then nodeunit could be for you.
Forms
Constructing a good form by hand is a lot of work. Popular frameworks like Ruby on Rails and Django contain code to make this process less painful. This module is an attempt to provide the same sort of helpers for node.js.
