Phoenix is the long-awaited web framework based on Elixir, the highly concurrent language that combines a beautiful syntax with rich metaprogramming. The best way to learn Phoenix is to code, and you’ll get to attack some interesting problems. Start working with controllers, views, and templates within the first few pages. Build an in-memory context, and then back it with an Ecto database layer, complete with changesets and constraints that keep readers informed and your database integrity intact. Craft your own interactive application based on the channels API for the real-time applications that this ecosystem made famous. Write your own authentication plugs, and use the OTP layer for supervised services. Organize code with modular umbrella projects.

This edition is fully updated for Phoenix 1.4, with a new section on using Channel Presence to find out who’s connected, even on a distributed application. Use the new generators and the new ExUnit features to organize tests and make Ecto tests concurrent.

This is a book by developers and for developers, and we know how to help you ramp up quickly. Any book can tell you what to do. When you’ve finished this one, you’ll also know why to do it.

What You Need

To work through this book, you will need a computer capable of running Erlang 18 or higher, Elixir 1.5 or higher, and Phoenix 1.4 or higher. A rudimentary knowledge of Elixir is also highly recommended.
