Miffy

Jiffy and JSX wrapper which returns a more standard Erlang map.

Usage

Optional data types can be passed as a second parameter, to provide seemless translation.

{deps,
 [
  {miffy, ".*", {git, "https://github.com/expelledboy/miffy.git", {tag, "2.0.0"}}},
  %% which requires either peer dependency
  {jiffy, ".*", {git, "https://github.com/davisp/jiffy.git", {tag, "0.14.11"}}},
  {jsx, ".*", {git, "https://github.com/talentdeficit/jsx.git", {tag, "v2.9.0"}}}
 ]}.

Types = #{ atom => atom,
       string => string,
       collection => {collection, #{ key => atom }},
       obj => #{ sub => atom } },
Erlang = #{ atom => value,
        list => ["value"],
        collection => [#{ key => one }, #{ key => two }],
        string => "value",
        bool => true,
        integer => 1,
        float => 1.0,
        obj => #{ sub => value } },
Json = miffy:encode(Erlang, Types),
AtomStr = '{"string":"value","obj":{"sub":"value"},"list":[[118,97,108,117,101]],"integer":1,"float":1.0,"collection":[{"key":"two"},{"key":"one"}],"bool":true,"atom":"value"}',
Json = erlang:atom_to_binary(AtomStr, latin1), %% HACK dont do this to create strings
Erlang = miffy:decode(Json, Types).

Note

Miffy does NOT attempt to translate lists deeply, see unit tests for example behaviour.

However (as seen above) a collection type exists, which is a list containing objects of the same type.
