A Json Serialization/Deserialization library that aims to create json documents from any nested data structures and deserialize json documents back to same datastructure.

iex(1)> map = %{"name" => "Joe", "age" => 21, "birthdate" => Date.new(1970, 1, 1) |> elem(1)}
%{"age" => 21, "birthdate" => ~D[1970-01-01], "name" => "Joe"}

iex(2)> {:ok, serialized} = JsonSerde.serialize(map)
{:ok,
"{"age":21,"birthdate":{"__data_type__":"date","value":"1970-01-01"},"name":"Joe"}"}

iex(3)> JsonSerde.deserialize(serialized)
{:ok, %{"age" => 21, "birthdate" => ~D[1970-01-01], "name" => "Joe"}}

Custom structs can be marked with an alias, so resulting json does not appear elixir specific

iex(2)> defmodule CustomStruct do
...(2)> use JsonSerde, alias: "custom"
...(2)> defstruct [:name, :age]
...(2)> end
{:module, CustomStruct,
<<70, 79, 82, 49, 0, 0, 5, 240, 66, 69, 65, 77, 65, 116, 85, 56, 0, 0, 0, 189,
  0, 0, 0, 18, 19, 69, 108, 105, 120, 105, 114, 46, 67, 117, 115, 116, 111,
  109, 83, 116, 114, 117, 99, 116, 8, 95, 95, ...>>,
%CustomStruct{age: nil, name: nil}}

iex(3)> c = %CustomStruct{name: "eddie", age: 34}
%CustomStruct{age: 34, name: "eddie"}

iex(4)> {:ok, serialized} = JsonSerde.serialize(c)
{:ok, "{"age":34,"name":"eddie","__data_type__":"custom"}"}

iex(5)> JsonSerde.deserialize(serialized)
{:ok, %CustomStruct{age: 34, name: "eddie"}}

Custom Structs

The type key included in all structs is defaulted to "data_type" but can be customized by:

config :json_serde, :type_key, "type"

• Note: This configuration is only read at compile time
