Work on node.js module in place

I'm working on my node.js demo.location.io web app at the same time as my location.io library. I'd like to be able to make changes to the location.io library and push them up to github from inside the node_modules folder. Is there any support for this in npm?

(If I understand your question) You can use

npm link 

to link your location.io to your local demo.location.io repo. More info here
