Build and test a blazing fast JSON API with Phoenix, an Elixir framework

Original Post

By Paul Smith March 20, 2015
Updated by: Brett Holt May 5, 2016

Note: This guide was written for Phoenix 1.1.4. Parts of it may no longer work if you are using a newer version.

Let’s build a JSON API that serves a list of contacts. We’ll be writing it using Elixir (version 1.2.5) and Phoenix (version 1.1.4). Phoenix is a framework written in Elixir that aims to make writing fast, low latency web applications as enjoyable as possible.
