immutable-json

Parse JSON into immutable.js collections

IJSON.parse is a collection of parsers, each interpretting JSON Arrays and Objects in different ways:

• IJSON.parse.ListMap - views JSON Arrays as Immutable Lists, and Objects as Maps.
• IJSON.parse.SeqMap - views JSON Arrays as Immutable Seqs, and Objects as Maps.
• IJSON.parse.SetMap - views JSON Arrays as Immutable Sets, and Objects as Maps.
• IJSON.parse.SetMapOrdered - views JSON Arrays as Immutable OrderedSets, and Objects as OrderedMaps.

Custom

If you need something that isn't in the presets, IJSON.generate can be used to build a new parser. It takes two arguments: first argument is a function for how to interpret JSON Arrays (in the form of a JavaScript Array), second argument is for interpreting JSON Objects (in the form of a JavaScript Array of Pairs).

var I = require('immutable');
var IJSON = require('immutable-json');
var parse = IJSON.parseWith(I.Seq, I.OrderedMap);

parser('[{"foo": "bar"}]').value;
> Seq [ OrderedMap { foo: "bar" } ]
