How to include node.js package that references a git repository

Greetings fellow meteorites. #oneLove.

I am currently using the meteorhacks:npm package to manage my node.js packages.
My main question:!

Using this package, what is the proper way to include a node.js package that references a github repo? The reason I am trying to do this is avoid pointing to one specific version (like meteorhacks requires) but then having to modify my packages.json file (for storing node packages) later when say a specific node.js package comes out with a new version.

Thanks in advance for you help :smile:
