Gin

Description

Gin is a small Ruby web framework, built on Rack, which borrows from Sinatra expressiveness, and targets larger applications.

Getting Started

Gin provides a simple command for setting up a new application.

$ gin path/to/appname

Hello World

A Hello World application requires at minimum a Gin::App instance and a Gin::Controller.

# config.ru
require 'gin'

class HelloWorldCtrl < Gin::Controller
  def index; "Hello World!"; end
end

class MyApp < Gin::App
  mount HelloWorldCtrl, "/"
end

run MyApp.new

Why Gin?

Gin tries to fill a need for a framework that’s simple and lightweight, yet scalable for large applications. Gin is comparable to Sinatra in performance and memory consumption, but supports multiple controllers and filters.
