A drop-in implementation of Backbone.sync that uses a Lawnchair instance for client-side persistence.
Lawnchair is a simple JSON storage engine that implements several legacy techniques for client-side persistence. If you're using a modern browser that implements the DOM localStorage APIs, you should probably use backbone.localStorage instead.
Include backbone.lawnchair.js after backbone.js:
<script type="text/javascript" src="backbone.js"></script>
<script type="text/javascript" src="backbone.lawnchair.js"></script>
Then specify the Lawnchair instance to use for each collections like so:
window.SomeCollection = Backbone.Collection.extend({
lawnchair: = new Lawnchair({ name: "SomeCollection"}, new Function()), // Unique name within your app.
// ... everything else stays the same
});
Based on Backbone.localStorage by Jerome Gravel-Niquet and others.
