If you’re a NodeJS user who happens to use Hudson as a continuous integration server, then perhaps you would be interested to check out NodeJS Plugin which I released about a month ago (yea, I’m always behind with blogging).
This plugin allows you to use NodeJS script on a build step, as an alternative to the existing shell script (out of the box) and Ruby script (via a plugin).
Call me too optimistic, but I’m waiting for the day when all standard shell script commands have their NodeJS equivalence.
