Fully updated to Elixir 1.15, this authoritative bestseller reveals how Elixir tackles problems of scalability, fault tolerance, and high availability.

Thousands of developers have learned to build applications in Elixir by using Saša Juric’s Elixir in Action. You’ll skip the programming basics or 101 introductions; this book builds on your existing knowledge to get you quickly writing real Elixir code. Along the way, you'll develop an appreciation for, and considerable skill in, functional and concurrent programming.

Inside Elixir in Action, Third Edition you’ll find:

• Updates for Elixir 1.15
• Elixir modules, functions, and type system
• Functional and concurrent programming
• Introduction to distributed system design
• Creating deployable releases

Fully updated to Elixir 1.15, this book contains new coverage of working with application configuration and the latest OTP releases. It teaches you the underlying principles and functional concepts of Elixir, and how each piece fits into the bigger picture of building production-ready systems with Elixir, Erlang, and the OTP framework.

Foreword by Francesco Cesarini.

About the technology

With best-in-class fault tolerance and concurrency, a pragmatic approach to functional programming, and the power to operate at scale, Elixir is the perfect choice for mission-critical software. Start reading Elixir in Action, and you’ll quickly understand why Elixir creator José Valim says it “...tops the list” of Elixir books.
