immpatch

Update immutable.js objects using JSON Patch operations

Install

$ npm install --save immpatch

Usage

var expect = require('expect.js');
var Immutable = require('immutable');
var patch = require('immpatch');

var object = Immutable.fromJS({ baz: 'qux', foo: 'bar' });

var patched = patch(object, [
  { op: 'replace', path: '/baz', value: 'boo' },
  { op: 'add', path: '/hello', value: ['world'] },
  { op: 'remove', path: '/foo'}
]);

expect(patched.toJS()).to.eql({
  baz: 'boo',
  hello: ['world']
});

For more information about JSON Patch, see:

For a diff / patch generator see immutablediff.

Another similar module is immutablepatch, immpatch is a simpler implementation that uses plain JS objects as patch operations, and has more complete tests with 100% code coverage.
