This repository is an empty Rails application showing you how to get HighCharts charts with realtime update, using Server-Sent Events through a complete async Rails stack.
This is explained on a blog post at http://blog.penso.info and you can see a live jsfiddle (without the SSE part).
$ git clone https://github.com/penso/blog-sse.git
$ cd blog-sse # This repository use RVM
$ bundle install
$ rails s
