npkill
easily delete all your old node_modules folders
I just deleted 8gb of old node_modules folders for inactive projects!
Just run npx npkill in your terminal, and npkill will scan your hard drive for all your node_modules folders, display the last time they were accessed, and let you delete them.
side note, npx is great for running node applications in a one-off context; Underappreciated NPM feature in my opinion.
