Rack is the foundation of every Ruby web application from micro service to major web framework. Yet, Rack lacks some basic features we all grew accustomed to. Rack::Support is just a small and modular library retrofitting those features. It is not a framework.

Oh my god ... this is Sinatra all over again, right?!


Add this line to your application's Gemfile:

gem 'rack-support'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rack-support
