This fork changes the format and it's no longer compliant with the RFC 6902.

- Patches are plain javascript objects
- The operators looks like { op: "+", path: ["d"], value: 4 }

Immutable Diff

Create RFC 6902 style patches between Immutable.JS data structures, such as Maps, Lists, and Sets.

Getting Started

Install immutablediff using npm or yarn:

`` shell


npm...

npm install --save immutablediff

...or yarn

yarn add immutablediff
`

You can then use it to get the diff ops between you Immutable.JS data structures.

` javascript
var Immutable = require('immutable');
var diff = require('immutablediff');

var map1 = Immutable.Map({a:1, b:2, c:3});
var map2 = Immutable.Map({a:1, b:2, c:3, d: 4});

diff(map1, map2);
// List [ Map { op: "add", path: "/d", value: 4 } ]
`

The result of diff is an Immutable Sequence of operations

Immutable Patch

If you want to use the resulting diff to apply patches to other Immutable data structures, you can use the package immutablepatch`. Source code available here
