npm-diff (GitHub: segmentio/npm-diff, License: MIT) is a utility module by Julian Gruber to diff two versions of NPM module. I’ve been fascinated recently by all the tools being released to help you manage package.json and module publishing. It’s really cool!

npm install npm-diff


$ npm-diff intersect 0.0.0 0.1.0 | colordiff

BOOM! brew install colordiff if you haven’t got it.
