rainbows-rails

rainbows-rails is a simple gem that sets the default server for rack (and rails) to rainbows.

rainbows-rails overrides the Rack::Handler.default method to return Rack::Handler::Rainbows which will cause rack (and rails) to use rainbows by default.

Add this line to your application's Gemfile:

gem "rainbows-rails"

And then execute:

$ bundle install

Just add the gem to your Gemfile and then rails server will default to using rainbows.
