I recently found a need for the CoffeeScript compiler[0] that runs on top of NodeJS. Its test suite requires a bunch of other javascript packages, and I wound up packaging enough of them to test CoffeeScript.
In the process I wrote an eclass to handle packages hosted on the npm registry[1] and install them globally. I put all of this in an overlay for now: https://github.com/orlitzky/npm We don't have any standalone javascript packages in the tree at the moment but I know there's been some interest before. Is anyone still (planning on) working on javascript stuff in-tree? If not, I'll probably commit dev-lang/coffee-script to the tree without its test suite. But if so, the eclass and few dev-js packages I have might be a good start. Then I could add coffee-script with its test suite working. [0] http://coffeescript.org/ [1] https://www.npmjs.com/
