About the Book

Learn best practice to build an API using Ruby on Rails 5. The intention with this book it’s not only to teach you how to build an API with Rails. The purpose is also to teach you how to build scalable and maintainable API with Rails which means improve your current Rails knowledge. In this book you will learn to:

  • Build JSON responses
  • Use Git for version controlling
  • Testing your endpoints
  • Optimize and cache the API

This book is based on "APIs on Rails: Building REST APIs with Rails". It was initially published in 2014 by Abraham Kuri . Since the original work was not maintained, I wanted to update this excellent work. All the source code of this book is available in Asciidoctor format on Github. So don’t hesitate to fork the project if you want to improve it or fix a mistake that I didn’t notice.
