Extendable Immutable.js

About

Ever wished that you could have OrderedMaps, Maps or Lists with extra methods, that make your life easier? .ofCourse()!

• Behaves like normal Immutable.js data structures
• Doesn't break Immutable.js' inheritance (*.is and instanceof still pass!)

Getting Started

Installing the latest version via npm takes just a second:

npm install --save extendable-immutable

Import what you need:

import { OrderedMap } from 'extendable-immutable'

class Collection extends OrderedMap {
// ...

Quick Intro

import { OrderedMap } from 'extendable-immutable'

class Collection extends OrderedMap {
  static isCollection(val) {
    return val && val instanceof Collection;
  }

  doMagic() {
    return this.map(x => x.set("magic", true));
  }
}

const magic = new Collection();

magic instanceof Immutable.OrderedMap; // true
Immutable.OrderedMap.isOrderedMap(magic); // true
