Shopify Application Development: Build Highly Effective Shopify Apps Using the Powerful Ruby on Rails Framework

Really good if you know a bit already, I would much prefer a video tutorial though, I would buy it straight away !

I've been working my way through and while the book is aimed more at beginners, it feels like it answers a need that's currently absent in the Shopify app development community: clear, concise examples & documentation about how to build an app using Ruby on Rails. I haven't found anything else like it and while I'm not a newbie to coding, web frameworks are something I've not had experience with and this book is filling in a lot of gaps in my knowledge.

Working through this book during my winter break, I'm really enjoying the writing style and methodology. This book not only shows you how to build a Shopify App, but it also gives you the proper Rails workflow using Git, Github, Heroku, Rspec and Guard. Support publications should be downloaded from the author's Github account, not PacketPub.
