This is a great read that can be applied to node.js very much. I've seen apps that include 10, maybe 20 dependencies but when you flatten out the full dependency tree? Thousands. It's incredible and if one of those dependencies screws up semantic versioning or just screws up in general it can be a nightmare to debug and fix.

This is why every 1.0 product I work on I include every dependency that speeds up my development. In 2.0 the first things to do is prune all unnecessary dependencies and start minor rewrites when a dependency can be done in house (yeah yeah reinventing the wheel is a problem but most npm dependencies are small and many can be recreated internally without issue).

This is even more important if you're creating a library / module. My msngr.js library uses zero dependencies and yet can make http calls in node and the browser because it was easy to implement the minimal solution I needed without bringing in dependencies to support a single way of calling http.
