Whenever I ask myself “Wait, what npm packages do I have installed globally?“ I find myself baffled to remember the exact command syntax. Everytime.
When you do a simple npm list -g - hence the -g or --global operates npm in global mode - it outputs in fact all globally installed packages, but also each and every of their corresponding dependencies. If you’re like me and have just a few npm packages installed this will result in a very long list and isn’t quite what I’d call an overview.
The magic argument doing the trick is --depth=0 and instead of searching for it one more time, I’ll put it here. For my own convenience and maybe for yours as well.
tl;dr#
npm list -g --depth=0
An alternative to get an overview of globally installed npm packages is ls `npm root -g`, but that won’t return the respective package versions. That’s why I prefer the command above.
