You will transform cluttered endpoints into elegant, maintainable code using modern Ruby and Rails design patterns. What you'll learn: Understand foundational pagination concepts and standard API response structures; Identify common pagination code smells and duplication in Rails controllers; Refactor pagination logic into reusable concerns and dedicated helper objects; Apply modern Ruby features like pattern matching and strict type hints to make your pagination robust; Configure metadata serialization to deliver clean JSON responses to your API clients; Write clean, isolated unit tests using pytest-inspired strategies adapted for Rails. We begin with essential API pagination terminology and architectural principles before diving into hands-on refactoring strategies. This course is designed for beginner to intermediate Rails developers looking to write cleaner, more professional backend code. Start writing elegant, maintainable API controllers today.
