title: Require Node.js dependencies in Ruby/Rails gem
body: <p>I'm having a great time live-reloading JS  with <a href="https://github.com/facebook/fb-flo" rel="nofollow">fb-flo</a> in my Rails &amp; <a href="http://batmanjs.org" rel="nofollow">batman.js</a> project. I want to move my code into a Ruby gem, but I don't know what to do. </p>
  
  <p>To run the <code>flo</code> server, I'll need to <code>require("fb-flo")</code>. If this was a node module, I'd just make sure to put my dependencies in package.json. But how can I require <code>fb-flo</code> (and its dependencies) in a Ruby gem? </p>
  
  <p>Or, should I just install the dependencies and include them in the gem's code?</p>
