Epoxy.js : Elegant Data Binding for Backbone

Epoxy.js is an elegant and extensible data binding library for Backbone.js; it provides feature-rich extensions of Backbone's Model and View components designed to hook view elements directly to data models. Epoxy captures some great aspects of Knockout.js and Ember.js in a familiar API that feels tastefully like Backbone, with minimal additional file size (~10k min, 2k gzip). Some key features in Epoxy include:

• Computed Model & View Attributes
• Declarative View Bindings
• Automated Dependency Mapping
• Automatic View Updates

Epoxy builds on jQuery/Zepto+Backbone and works where they work: IE6+, Firefox 3+, Safari, Chrome.

Installation

Epoxy requires jQuery 1.7.0+, Underscore 1.4.3+, and Backbone 0.9.9+. To quickly install Epoxy, download the full Epoxy library (backbone.epoxy.min.js) and include its script tag in your document after all dependencies:

<script src="jquery-min.js"></script>
<script src="underscore-min.js"></script>
<script src="backbone-min.js"></script>
<script src="backbone.epoxy.min.js"></script>

You may choose to replace jQuery with Zepto and/or Underscore with Lo-Dash. Also remember to include the json2 library when targeting IE6/7.
