IncludeJS - Use CommonJS modules inside Ruby/Rails
github.com/walskiA friend of mine found himself in the situation of having to implement the same business logic in both Javascript and Ruby.
So he wondered how to get rid of that duplication. The solution he came up with is IncludeJS which allows you to implement something in Javascript and use that code _both_ in Javascript and in Ruby.
He gave a talk on this topic during RailsConf2011, which provides some more details: http://en.oreilly.com/rails2011/public/schedule/detail/1941
