Off The Rails: Web Apps With Rack, Sinatra, Grape, and Siesta

This is a talk and related code written by Alex Chaffee about Rack apps and Ruby webapp frameworks that are not on Rails. It lives at https://github.com/alexch/off-the-rails

off-the-rails.md is the markdown document of the "slides" (more like notes) for the presentation.

app.rb is a little Rack app that renders the slides into HTML and wraps them in a page with some CSS. Run it with ruby app.rb (or ruby -rrubygems app.rb if you're on Ruby 1.8)

rack/ and sinatra/ contain sample apps and middleware that are referenced by the talk.

rack/redirect_host.rb is a middleware component pulled from a real app that redirects from one host to another, e.g. from foo.heroku.com to www.foo.com.
