Preface

It doesn’t seem possible, but it’s been three years since we released the first edition of this book. Indeed, the Phoenix team has been busy. The additions of Channel Presence and LiveView are changing the way all programmers think about web development. The underlying directories have changed, having a rippling impact on all of the code in this book. Ecto has also produced a major release.

Through it all, one thing remains constant. Phoenix is still positioned as one of the most productive and scalable web development platforms available anywhere. From cryptocurrencies to media companies to commerce, Elixir developers are using Phoenix to push the boundaries of what’s possible. In this book, the same folks who built Elixir and Phoenix will show you how you can do the same.
