bredele-store v0.2.0

store

Store component is a single wrapper for your models and collections (inspired by Olives.js).

Some front end framework provide collections which are basically ordered sets of models (or arrays of objects) with no extra features. Store removes this overhead and helps you focus on your data instead of maintaining something useless.

Store contains your data and all the logic surrounding it such as formatters, access control, computed properties, reset, local storage and can be easily extended with its middleware engine.

Installation

component:

$ component install bredele/store

nodejs:

$ npm install bredele-store

Browser Support

Store supports all mainstream browsers from IE8+. Supports IE7 with JSON polyfill.

//update 0
store.set([{
  name: 'olivier',
  github: 'bredele'
}]);
