Books

Programming Elixir 1.6

This book is the introduction to Elixir for experienced programmers, completely updated for Elixir 1.6 and beyond. Explore functional programming without the academic overtones (tell me about monads just one more time). Create concurrent applications, but get them right without all the locking and consistency headaches.

Meet Elixir, a modern, functional, concurrent language built on the rock-solid Erlang VM. Elixir’s pragmatic syntax and built-in support for metaprogramming will make you productive and keep you interested for the long haul. Maybe the time is right for the Next Big Thing. Maybe it’s Elixir.

Elixir in Action

Elixir in Action is a tutorial book that aims to bring developers new to Elixir and Erlang to the point where they can develop complex systems on their own. No knowledge about Elixir, Erlang, or functional programming is required, but it is assumed that a reader has a few years of production experience using mainstream OO languages, for example C#, Java, Python, or Ruby.

The book starts with a basic introduction to the Elixir language and functional programming idioms. The central part of the book deals with Erlang VM and OTP, discussing topics such as concurrent programming, fault-tolerance, and distributed systems. Finally, you’ll learn how to package your code into components, create a standalone deployable release, and troubleshoot the running system. The theory is demonstrated through a simplistic example that is gradually expanded throughout the book into a fully standalone releasable system.

Adopting Elixir

Adoption is more than programming. Elixir is an exciting new language, but to successfully get your application from start to finish, you’re going to need to know more than just the language. You need the case studies and strategies in this book.

Learn the best practices for the whole life of your application, from design and team-building, to managing stakeholders, to deployment and monitoring. Go beyond the syntax and the tools to learn the techniques you need to develop your Elixir application from concept to production.

Introducing Elixir

Elixir is an excellent language if you want to learn about functional programming, and with this hands-on introduction, you’ll discover just how powerful and fun Elixir can be. This language combines the robust functional programming of Erlang with a syntax similar to Ruby, and includes powerful features for metaprogramming.

This book shows you how to write simple Elixir programs by teaching one skill at a time. Once you pick up pattern matching, process-oriented programming, and other concepts, you’ll understand why Elixir makes it easier to build concurrent and resilient programs that scale up and down with ease.

The Little Elixir and OTP Guidebook

The Little Elixir & OTP Guidebook gets you started programming applications with Elixir and OTP. You begin with a quick overview of the Elixir language syntax, along with just enough functional programming to use it effectively. Then, you’ll dive straight into OTP and learn how it helps you build scalable, fault-tolerant and distributed applications through several fun examples. Come rediscover the joy of programming with Elixir and remember how it feels like to be a beginner again.

Elixir Cookbook

This book is a set of recipes grouped by topic that acts as a reference to get ideas from or to quickly search for a solution to a problem. You will begin by launching an IEx session and using it to test some ideas. Next, you will perform various operations like loading and compiling modules, inspecting your system, generating a supervised app, and so on. Furthermore, you will be introduced to immutability, working with data structures, performing pattern matching, and using stream modules to generate infinite data sequences. You will learn about everything from joining strings to determining the word frequency in text. With respect to modules and functions, you will also discover how to load code from other modules and use guards and pattern matching in functions.

Elixir School

Elixir-School is an open and community driven effort inspired by Twitter’s Scala School. The site’s content consists of peer-reviewed lessons on various Elixir topics that range in difficulty. The lessons are currently available in over 10 languages to help make programming Elixir more accessible to non-English speakers.

Joy of Elixir

Joy of Elixir is a gentle introduction to programming, aimed at people who already know some things about computers, but who have little-to-no programming experience.

This book will teach you the core concepts of the Elixir programming language in a fun and enjoyable way. If you’re completely new to programming and you want to learn how to make a computer do things using the power of programming and you want to experience some joy while doing it, then read this book!

Learn Functional Programming With Elixir

Elixir’s straightforward syntax and this guided tour give you a clean, simple path to learn modern functional programming techniques. No previous functional programming experience required! This book walks you through the right concepts at the right pace, as you explore immutable values and explicit data transformation, functions, modules, recursive functions, pattern matching, high-order functions, polymorphism, and failure handling, all while avoiding side effects. Don’t board the Elixir train with an imperative mindset! To get the most out of functional languages, you need to think functionally. This book will get you there.

Video/Interactive Resources

Pragmatic Studio's Elixir/OTP Course

Put Elixir and OTP into action as you build a concurrent, fault-tolerant application from scratch in this 6-hour video course from The Pragmatic Studio. By developing a real app with real code, you’ll gain practical experience putting all the pieces together to craft applications the Elixir/OTP way.

The first half of the course focuses on core Elixir facets, principles, and techniques. In the second half, we go beyond the basics and focus on what sets Elixir/OTP apart: concurrent processes, the actor model, OTP behaviors, and fault recovery.

If you’re new to Elixir, you’ll get step-by-step guidance in an engaging format you won’t find anywhere else. If you have experience with Elixir, you’ll gain a deeper understanding of things you’ve been taking for granted and fill in any knowledge gaps.

Other Resources

Elixir Flashcards

Elixir flashcards are a set of beautifully crafted, professionally printed, poker sized flashcards to help you master the Elixir language.

Flashcards are a great way to highlight knowledge gaps, identify misconceptions or false beliefs, and help you memorise key concepts. When used in groups or teams, flashcards can help spark interesting discussions, and help bring people together to learn in a fun way by playing games.
