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.

Source Code: The source code after finishing this guide can be found here.

# Elixir has lazily evaluated enumerable objects that allow you
# to work with enumerable objects like lists either only as needed
# or infinitely.

# Start up iex to play around
$ iex

# Typical enumeration is done eagerly where the result is computed ASAP
iex> Enum.map(1..10, fn i -> i * 2 end)

rename a section of a filename, i. e. example.1.{txt,conf,db} or 12345.1.{wav,ogg,mp3} and

change the 1 to a 2 in the filename while preserving the rest of it.

$ zmv -n '(.)(<->)(.[^.]#)' '$1$(($2+1))$3' # would rename x.0001.y to x.2.y. $ zmv -n '(.0#)(<->)(.[^.]#)' '$1$(($2+1))$3'

Rename files to lower case

$ zmv '*' '${(L)f}'

serially all files (foo.foo > 1.foo, fnord.foo > 2.foo, ..)

$ autoload zmv
