Quite simply a localStorage adapter for Backbone. It's a drop-in replacement for Backbone.Sync() to handle saving to a localStorage database.
Include Backbone.localStorage after having included Backbone.js:
<script type="text/javascript" src="backbone.js"></script>
<script type="text/javascript" src="backbone.localStorage.js"></script>
Create your collections like so:
window.SomeCollection = Backbone.Collection.extend({
localStorage: new Store("SomeCollection"), // Unique name within your app.
// ... everything else is normal.
});
Feel free to use Backbone as you usually would, this is a drop-in replacement.
Thanks a lot to Jeremy Ashkenas who refactored pretty much the whole code.
