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

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

Let’s build a JSON API that serves a list of contacts. We’ll be writing it using Elixir and Phoenix. Phoenix is a framework written in Elixir that aims to make writing fast, low latency web applications as enjoyable as possible. This will not go through installing Elixir or Phoenix. See the Phoenix Guides to get started.
