Overview

Webconsole is a Rack middleware that provides an interactive console à la Rails console, but for any kind of Rack application (Rails, Sinatra, Padrino…), accessible from your web application's front-end.

For every request, it normally passes control to the Assets middleware, which injects needed JavaScript, CSS and HTML code for the console to work properly.

It also exposes a special route used by the Repl, a Ruby evaluator which is responsible of keeping state between requests, remembering local variables and giving a true IRB-esque experience.
