An extension which provides a sync implementation through locally stored
key value pairs, either through the HTML localStorage API or falling back
onto an in-memory cache, that can be mixed into a Model or ModelList subclass.

A group of Models/ModelLists is serialized in localStorage by either its
class name, or a specified 'root' that is provided.

Sets up a Todo to be use LocalStorage as a synchronization layer.

Code Sample

<script src="http://yui.yahooapis.com/3.5.1/build/yui/yui-min.js"></script>

var Todo = Y.Base.create('todo', Y.Model, [Y.ModelSync.Local], {
        // Set up the root localStorage key we save our Model data in.
        root: 'todos-yui',
 
        // Toggle the completed state of the Todo.
        toggle: function () {
            this.save({completed: !this.get('completed')});
        },
 
        // Destroy this Todo and remove it from localStorage.
        clear: function () {
            this.destroy({remove: true});
        }
 }
