Advanced Functional Programming with Elixir

Use advanced functional programming principles, practical domain-driven design techniques, and production-ready Elixir code to build scalable, complex systems from simple, reusable components.Combine advanced functional programming concepts with production-ready Elixir and proven domain-driven design techniques to write cleaner, more thoughtful software. Youll explore foundational ideas like equality, ordering, predicates, monoids, and monadsthen go beyond syntax as you develop intuition for composing logic, modeling behavior, and growing systems. With a focus on maintainable, declarative code over theory, youll gain practical, composable patterns you can apply right away.Get ready to manage crowds, adjust priorities, and keep everyone safe in FunPark, a place that never sits still. Your job is to model that complexity and build the systems that keep everything running smoothly, even as the business team is still figuring out what they want and the experts keep rewriting the rules.Using core abstractionsequality, ordering, predicates, monoids, and monadsyou'll break problems into small, composable pieces that are both well-behaved and easy to combine. Rather than getting bogged down in theory or formal proofs, youll dive into real-world Elixirusing protocols, structs, and pattern matching to express shared behavior across your domain. Along the way, you'll build the vocabulary and mental models you need to organize complex logic, supported by a production-ready open-source library you can use, extend, and explore in your own projects.Whether you're an Elixir developer mastering functional programming or a functional programmer exploring Elixir, you'll discover how to write code thats easier to reason aboutand create systems that stay understandable, even as they grow.What You Need:To follow along with the examples in this book, youll need Elixir version ~> 1.16, access to the interactive shell (iex), and a code editor that supports Elixir syntaxsuch as Visual Studio Code, Neovim, or any editor you're comfortable with. You wont need Phoenix or any additional setup; the examples are minimal and self-contained, so you to focus on functional concepts without configuration overhead.
