Native JSON library for Elixir

Elixir JSON

This library provides a natively implemented JSON encoder and decoder for Elixir.

All contributions are welcome.

Installing

Simply add {:json, "~> 1.0"} to your project's mix.exs file, in the dependencies list and run mix deps.get json.

Example for a project that already uses Plug:

defp deps do
  [{:cowboy, "~> 1.0.0"},
   {:plug, "~> 1.0"},
   {:json, "~> 1.0"}]
end

Usage

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)
  # 41

Decoding 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"
