Building An Addon - Top Down/Bottom up

In this talk we'll take a look at how to build a Heroku Add-On from the top down and bottom up. We'll start by going over the general design and strategy of how an add-on works. We will then see how the the kensa gem allows you to test a local add-on you can develop in any language, like Ruby. Bring your laptop and you'll walk away with a working prototype in Sinatra.

Chris is a current member of the Heroku Add-ons team and loves a good pull request.
