Not sure about pypi but any non-trivial node app has exponentially more package dependencies compared to a similar sized ruby or go app, due to a combination of the "micropackage" fad and the language is a bit of a fragmented mess with a not great standard library. You end up with a lot of polyfills, normalization, and helper functions that are wrapped as their own library.

That's my experience, anyways, having previously worked on a large rails application, as well as large golang applications, and now spending most of my time in a typescript project.
