Rack - A Framework to Roll Your Own
summary
Shows how Rack’s actual call contract returns [status headers body] and how config.ru is evaluated inside a Rack::Builder stack so middleware like Rack::Reloader, Rack::ShowExceptions and Rack::Lint run by default. Builds a tiny framework (justrails) that autoloads controllers via an ActiveSupport-style inflector, renders views with Tilt templates, exposes each controller action as a Rack app (proc), implements routing with a simple hashmap, demos on config.ru on port 9292 and mentions a toy server (Chou) listening on port 4321.
