Object-oriented JavaScript (or CoffeeScript)

This is a bundle of tools for helping you to create well organized client-side code to be run in browsers covered by tests (or specs) in an easy way.

It uses:

  • oojspec for writing specs;
  • jQuery, the excelent DOM manipulation library;
  • FakeAjaxServer for simulating AJAX requests made with jQuery. It uses Sinon.js for stubbing jQuery.ajax() calls;
  • js-modules for splitting your spec "classes" in multiple files for better maintainance;
  • jQuery BBQ: don't count on that. Currently it is there only to provide $.deparam, for helping testing params processed by plugins, like jQuery form. If you don't need it, just don't include it;
  • The Rails Asset Pipeline. Yeah, sorry if you don't use Rails, but this can still be helpful for non-Rails applications.


Add this line to your application's Gemfile:

gem 'oojs'

And then execute:

$ bundle


I intend to write an article about it soon.

For now, you'll need to create your spec helper first:

rails g oojs:spec_helper

Then, create some spec:

rails g oojs:spec shopping_cart

Finally, run your specs:

rake sandbox_assets:serve

And navigate to http://localhost:5000/ to see them passing.
