will have to wait for @mariocasciaro, since he can publish it to npm
although npmjs search is pretty bad when it comes to filtering keywords (or maybe it changed). I usually search using http://node-modules.com/ (first result when searching for deep path)

[stevemao]

I was searching for dot-notation because that's how we call it in MongoDB. I could find other similar modules but not this one.

I guess it does no harm in adding a few more keywords. Thanks @stevemao .
