on beanstalk, you can see node logs at /var/log/nodejs/nodejs.log
on beanstalk, if you proxy via nginx, check those logs here /var/log/nginx/error.log

proper way to make a mod to a repo and grab it with npm (http://debuggable.com/posts/how-to-fork-patch-npm-modules:4e2eb9f3-e584-44be-b1a9-3db7cbdd56cb)

    Fork the project on GitHub
    Clone the fork to your machine
    Fix the bug or add the feature you want
