Description

Elixir and Phoenix for Beginners: Build real-world Elixir and Phoenix apps the practical, TDD way.

Learn to build fast, scalable, and fault-tolerant applications with Elixir and Phoenix through practical, hands-on development.

Elixir is a modern functional programming language built for performance, reliability, and concurrency. Running on the battle-tested Erlang Virtual Machine (BEAM), it enables developers to create highly available systems capable of handling massive workloads while remaining resilient to failures. Whether you’re building web applications, distributed services, or real-time systems, Elixir provides the tools needed to deliver dependable software at scale.

This practical guide takes you step by step from the fundamentals of functional programming to developing production-ready applications with Elixir and the Phoenix Framework. Along the way, you’ll build a solid understanding of Elixir’s syntax, data structures, and functional programming principles before exploring the BEAM’s unique concurrency model, lightweight processes, and OTP architecture.

Using practical examples, coding exercises, and project-based learning, you’ll discover how to design reliable services with GenServers and supervision trees, write automated tests using ExUnit, streamline development with Mix, and build powerful web applications using Phoenix and Ecto for database management.

By the end of the book, you’ll have the knowledge and confidence to design, build, deploy, and maintain scalable Elixir applications that are ready for real-world production environments.

What You’ll Learn

• Understand functional programming concepts and the BEAM runtime.
• Master Elixir syntax, pattern matching, and core data structures.
• Build concurrent and fault-tolerant applications using OTP.
• Create resilient services with GenServers and supervision trees.
• Develop modern Phoenix web applications with reusable components.
• Interact efficiently with databases through the Ecto library.
• Write comprehensive tests using ExUnit and automate workflows with Mix.
• Package and deploy production-ready Elixir applications.
• Reinforce your skills by completing a full Test-Driven Development (TDD) capstone project.

Who This Book Is For

This book is ideal for beginners learning Elixir, software developers transitioning from languages such as Python, PHP, Node.js, or JavaScript, backend and full-stack engineers interested in functional programming, and students looking for a practical introduction to Elixir, OTP, Phoenix, and Ecto. Its project-driven approach makes it equally valuable for anyone preparing to build scalable, production-quality Elixir applications.
