This is a simple proof-of-concept Rails app that uses the 1.x prerelease version of the react-rails gem, which lets us:

• render React components server side
• mount the same React component on top of the server-rendered DOM client side (via an unobtrusive JS adapter)

The app displays a photo with simple list of comments and a form for adding new comments. New comments are added via Ajax, but if JS fails to load (which you can test with ?js=broken), the form submits via a full page refresh.

To get the app running:

• bundle install
• rake db:migrate
• rails server
