This repository is a demo project for Coach.

Coach makes it simple to build maintainable, testable, reliable and well-engineered HTTP endpoints (especially APIs) in Ruby, moving away from monolithic ActionController controllers towards chains of Coach middleware, each with a single responsibility.

This project is designed to make clear the challenges and pains that come from using ActionController for anything beyond the most simple endpoints, and then show how you can solve these problems using Coach.

This project does not contain an application you'd actually want to run! It contains a simple, tested API built using Rails's ActionController (see app/controllers/attendees_controller.rb and spec/controllers/attendees_controller_spec.rb), and then that same API built using modular Coach middleware (see app/routes, spec/routes and spec/requests).

All we've built is a simple API for viewing attendees of an event. But including common functionality like authentication and internationalisation already begin to show the growing pains that come with controllers.
