So you heard that Rails is not good for doing APIs. A robust framework with a extended view layer and an asset pipeline cannot produce fast APIs. Right?
Wrong! In my talk I'll go over how to have a fast API within your Rails application, with topics including:
Understanding what is actually happening when your Rails app is producing the response
Minimizing external calls to a minimum
Digging deeper within ActionController to get extra juice
Decoupling representation to optimize performance
This talk is based on what we've done at Future Simple to tune our Rails apps and the awesome work Rails Core is doing to better support APIs.
