You already know the basics of Elixir. Maybe you have even shipped something to production. That's awesome! But how can you go one step further in your Elixir developer journey?
This book will help you to become a better Elixir developer by teaching you how to leverage the power of the BEAM runtime with recipes and patterns specific to Elixir/OTP.
About the book
The idea of having a "go-to" toolbox of patterns that you can leverage is an enticing one. That's what design patterns are about. But, design patterns are usually abstract and do not leverage unique properties of your specific run-time or language. That's how this book is different.
This book aims to surface the powerful and unique characteristics of the Erlang virtual machine (or BEAM for short) and show you how you can go about solving everyday problems in a simple yet scalable way.
Not only will you learn how to better leverage the tools that are at your disposal courtesy of Erlang and the BEAM, but you will also learn how to better utilize Functional Programming in order to achieve your goals in a clear and concise way. You'll start off by learning about some of the Erlang standard library utilities that are available to you right out of the box, and then you'll learn how to put those to use in your stateful GenServer powered applications.
