* I sometimes had to run "npm i" twice in order to get it to work. * It would often fail randomly. * node_modules has a fixed location. * There is a ludicrous number of dependencies even for the simplest projects. ~1000 is not unusual. Reasoning about that dependency tree simply isn't possible. * There was even a package to detect if a number was negative. It had a version 2 because there was a bug! * In general even small projects took an age to build. I'm sure this isn't all the craziness, it's just the stuff I ran into during my (fairly limited) exposure to npm packaging.
