As I have begun to include Bootstrap 3.0.0 (and especially it's new responsive mobile framework) into my web application development, it has become clear that someone needs to DRY this process up. So I quickly built a simple gem to do this: Bootstrap-Rails-Three.
Version 3.0.0 of Bootstrap contains some really powerful new capabilities, as well as some good-looking updates to the CSS itself. That said, it should be noted that v.3.0.0 is a work in progress and is subject to bugs and/or breaking changes. It should be used in production apps at your own peril.
Installation is simple. Just add this line to your application's Gemfile:
gem 'bootstrap-rails-three', :github => 'asanderson15/bootstrap-rails-three', :branch => 'master'
And then execute:
$ bundle install
Or install it yourself as:
$ gem install bootstrap-rails-three
Once the gem is installed, add the following code to your application.css and application.js files:
//= require twitter/bootstrap
*= require twitter/bootstrap
I hope this is useful for other developers trying to experiment with the new Bootstrap 3.0.0. If you have any comments or questions, don't hesitate to contact me on Twitter. If people show a lot of interest, I will try to be more diligent about keeping it up to date with the latest updates to Bootstrap as it continues towards a release version.
