Gin is a small Ruby web framework, built on Rack, which borrows from Sinatra expressiveness, and targets larger applications.
Gin provides a simple command for setting up a new application.
$ gin path/to/appname
A Hello World application requires at minimum a Gin::App instance and a Gin::Controller.
# config.rurequire'gin'classHelloWorldCtrl<Gin::Controllerdefindex; "Hello World!"; endendclassMyApp<Gin::AppmountHelloWorldCtrl, "/"endrunMyApp.new
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.
