Is it really accurate to call socket.io a "non-web" library? Even lodash is questionable in that category - while not strictly tied to the web, it is primarily used in web apps. I'd be curious to see lower level stuff and/or stuff further removed from the web in the non-web category.
I write a lot of ETL scripts in Node for https://www.findlectures.com use lodash in pretty much everything, for me it basically serves the role of collections libraries in other languages
