This library provides a natively implemented JSON encoder and decoder for Elixir.
You can find the package in hex.pm and the documentation in hexdocs.pm.
All contributions are welcome!
Simply add {:json, "~> 1.4"} to your project's mix.exs and run mix deps.get.
Encoding an Elixir type
@doc "
JSON encode an Elixir list
"
list = [key: "this will be a value"]
is_list(list)
# true
list[:key]
# "this will be a value"
{status, result} = JSON.encode(list)
# {:ok, "{\"key\":\"this will be a value\"}"}
String.length(result)
# 41Decoding a list from a string that contains JSON
@doc "
JSON decode a string into an Elixir list
"
json_input = "{\"key\":\"this will be a value\"}"
{status, list} = JSON.decode(json_input)
{:ok, %{"key" => "this will be a value"}}
list[:key]
# nil
list["key"]
# "this will be a value"At any time, you can turn on verbose logging for this library only. To do so, head to config file of your application and add below lines:
use Mix.Config
config :logger, level: :debug
config :json, log_level: :debugNote that, changing only :logger level to :info, :warn or :error will silent :json too.
