The Outdated Sale

Because the books are still frozen in time (yep, still on Rails 5), they’re 20% off for now! We’re actively upgrading everything to Rails 6, 7, and 8 (complete with upgrade guides), so this discount won’t stick around long. Grab it while the books are still catching up!

Master the entire API lifecycle

A hands-on Ruby course that takes you from HTTP fundamentals to fully functional, maintainable Web APIs built with modern best practices.

Practice over theory

Build real Ruby APIs while learning HTTP the right way

Module 1 (Chapters 2-10)

Simple Sinatra APIs to understand the basics of the Web

With a mix of history, web standards, and best practices, this module will equip you with strong web API foundations to kickstart your learning. Understand HTTP, caching, versioning, authentication, and much more! But it’s not just theory - you’ll discover how to build Sinatra APIs with everything you’ve learned so far.

Module 2 (Chapters 11-28)

Building a complete web API with Rails 5

You’ll build a real application — an e-commerce API for selling digital books. To keep your code robust, we follow a test-driven approach and go beyond the “Rails Way” when needed to keep things clean and maintainable. This isn’t just a tutorial app: you’ll integrate everything required to ship and deploy your API to Heroku.

Some of the key highlights:

  • A complete set of resources to sell books (books, publishers, authors, purchases, etc.)
  • A secure authentication mechanism for clients AND users that will protect us (from timing attacks for example).
  • A bunch of optimization tricks with compression and caching.
  • A set of custom made tools to handle the representations generation (representation builders, query builders, serializers, etc.)
  • Support for CORS requests in order to build JavaScript clients.

Module 3 (Chapters 28-32)

Understanding REST and turning Alexandria into a hypermedia API

In the last module, you’ll discover REST and what it really is (hint: it’s probably more than you think)! You’ll review the REST constraints and learn why Alexandria cannot be considered a REST API. We’ll also explore what needs to be changed to make that happen. Then you’ll learn how to transform Alexandria into a hypermedia API and discuss some of the options regarding hypermedia formats.

Loved by developers shipping Ruby APIs

I really enjoyed reading this well-researched book on APIs. I've learned so much from the examples and explanations and will keep it as a reference guide.

Why did I create this course?

Hi, I'm Tibo. 👋

I've been building Web APIs for the past 12 years using technologies like Ruby, Elixir, JavaScript, and Go.

Before writing Master Ruby Web APIs, I spent countless hours digging through books and RFCs to gather the knowledge I needed.

Now, I want to share everything I've learned with you, so you can master the web foundations without the same struggles.
