Clojure Protocols and Records: Structural Typing for Functional Programs

Clojure offers powerful ways to manage data and behavior without relying on traditional object-oriented inheritance. Understanding Protocols and Records is essential for writing clean, extensible, and high-performance functional code. This course guides you through defining custom data structures and abstract interfaces, enabling you to build applications that are easy to maintain and scale. By the end, you will be proficient in leveraging Clojure's core mechanisms for data modeling and polymorphism. What you'll learn: * Understand the fundamental differences between Records, Maps, and Types in Clojure. * Define abstract interfaces using Protocols to enable dynamic dispatch and polymorphism. * Practice creating and manipulating immutable data structures efficiently using Records. * Apply the extend-type and extend-protocol functions for adding custom behaviors to existing types. * Learn how to integrate structurally defined data with modern specification tools for validation and documentation. We begin with key terminology and foundational concepts before moving into practical examples that demonstrate how to implement and use these features in real-world scenarios. This course is designed for beginners who have a basic understanding of Clojure syntax and functional programming concepts and wish to deepen their knowledge of data modeling. No prior experience with structural typing or advanced features is required. Start reading today to unlock the full potential of data modeling in Clojure.
