JSON for Elixir
Elixir implementation (with an Erlang parser) of the JSON specification to RFC 4627. ExJSON generate JSON string from keyword lists and maps and can parse into those structures also.
Installation
Add HTTPoison to your mix.exs dependencies:
def deps do
[{:exjson, "~> 0.6.0"}]
endand run $ mix deps.get.
Generating a JSON string from a keyword list
ExJSON.generate([ key: "some value" ])
#=> "{\"key\":\"some value\"}"
ExJSON.generate([ k: [ 1, 2, 3 ] ])
#=> "{\"k\":[1,2,3]}"
ExJSON.generate([ k1: [ k2: [ k3: "v3" ] ] ])
#=> "{\"k1\":{\"k2\":{\"k3\":\"v3\"}}}"
ExJSON.generate([
image: [
width: 800,
height: 600,
title: "View from 15th Floor",
thumbnail: [
url: "http://www.example.com/image/481989943",
height: 125,
width: 100
],
ids: [ 116, 943, 234, 38793 ]
]
])
#=> "{\"image\":{\"height\":600,\"ids\":[116,943,234,38793],\"thumbnail\":{\"height\":125,\"url\":\"http://www.example.com/image/481989943\",\"width\":100},\"title\":\"View from 15th Floor\",\"width\":800}}"Generating a JSON string from a map
