Export Import npm Packages

Question

I would like to reinstall npm from scratch. I want to reinstall packages already installed globally in npm after reinstallation. What would be a safe (and not manual) way to export and import globally installed modules?

Implementation note: my old npm also required sudo for global installations, so I am not trying to reuse the same directory, instead of the new npm installing the same package list as the old one.

Answer 1

npm ls -g --depth=0

( ), . npm install, ( , / ...)

Answer 2

TL;DR

# Export
npm list --global --parseable --depth=0 | sed '1d' | awk '{gsub(/\/.*\//,"",$1); print}' > path/to/npmfile

# Import
xargs npm install --global < path/to/npmfile

, , , / NPM.

npm list :

$ npm list` --global --depth=0
