One of the things I like about node_modules is that it's not purely source code and it's not purely build artifacts. You can read the code and you can usually read the actual README/docs/tests of the package instead of having to find it online. And you can usually edit library code for debugging purposes. If node_modules is taking up a lot of space across a bunch of old projects, just write the `find` script that recursively deletes them all; You can always run `npm install` in the future when you need to work on that project again.
