Bit of a confusing name, when there is already an extremely popular mongodb node.js framework called Mongoose
Disagree with the downvote. Never used mongoose, nor am i a node developper, yet my first reaction was to wonder why a js db library evolved in an iot framework.
I think Mongoose was called mongoose before mongo db plugin existed.
https://github.com/cesanta/mongoose - that's the project from which Mongoose OS stems.
