How to build a JSON API with Elixir & Phoenix

Welcome! In this guide we'll go step by step to build an API with Elixir and the Phoenix Framework.

Note, i wrote this around 2017/18 so things might have changed. Also it's incomplete. Hopefully still useful. Yadayada.

Here's the plan:

I hereby claim:

I am ekhall on github.
I am eugekev (https://keybase.io/eugekev) on keybase.
I have a public key whose fingerprint is CF3C CF7A D21D DFD0 DC64 A517 0F9D 881D 59D3 8232

To claim this, I am signing this object:

	{-# LANGUAGE OverloadedStrings #-}
	module Escrow where

	import Language.Marlowe

	main :: IO ()
	main = print . pretty $ contract


	{- What does the vanilla contract look like?

	(ns giggin.api
	(:require [ajax.core :refer [GET]]
	[giggin.state :as state]
	[clojure.walk :as walk]))

	(defn handler
	"Resets the state/gigs atom (app state) to the response of the following data
	transformation. A GET request is made to the URL below in fetch-gigs. The
	keywords? option below turns all JSON key strings into symbols (`key`: `string`
	to :key `string`). The `response` is then passed to the series of function calls."
