This is a follow up to my first Rack screencast, Rack Basics.

In this screencast, we cover a bit more of the basics. Instead of playing around in an IRB shell, we create an executable Rack application using a Rackup file (the conventional way to run Rack applications).

We use some Rack middleware and learn howto to read Rack Requests a bit easier and howto generate Rack Responses a bit easier. We also catch some exceptions and get our Rack apps reloading.

I hope you enjoy this screencast. Next up in the Rack screencast mini-series: Rack middleware! You’ll learn how middleware works, how to create your own, and and examples of how to use lots of pre-existing Rack middleware.
