title: bundle.js appears to be to large for Github
body: <p>I have a simple test React.js app that I have put together, and I'd like to host it on Github.  However when I bundle / compile the app the size of the <code>bundle.js</code> file is ~ 4.5MB.  And apparently, Github won't allow files that are this size to be served for <code>gh-pages</code>.</p>
  
  <p>Does anyone know the max file size I can make the <code>bundle.js</code> in order for it to work on Github?</p>
  
  <p>Second, how could I split the <code>bundle.js</code> into smaller sizes so that it works on Github?</p>
