IncludeJS

Load CommonJS Modules into Ruby.

Currently it supports the CommonJS Modules 1.0 spec.

It uses therubyracer.

Synopsis

Writing a CommonJS Module in JavaScript

Inside 'helpers.js':

var a = 42;
exports.foo = function() {
  return 42;
}

Loading a CommonJS Module from Ruby

helpers = IncludeJS.require('helpers') # This returns a V8::Object
helpers.foo # => 42

Loading a CommonJS Module as a Ruby Module

class App
  include IncludeJS.module('helpers')
end
App.new.foo # => 42

You can set one root path from where to load .js files

IncludeJS.root_path = 'my/app/javascripts'

Have fun.

Running the specs

git submodule update --init
bundle install
bundle rspec spec    

Speed

Simple benchmarks are showing a noticeable gain of speed when using JS methods instead of native Ruby ones. While the Google V8 seems to be 10x faster than Ruby 1.8.7 it is still 4x as fast as Ruby 1.9.2
