Backbone localStorage Adapter v1.1.0

Quite simply a localStorage adapter for Backbone. It's a drop-in replacement for Backbone.Sync() to handle saving to a localStorage database.

Usage

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({

  initialize: function() {
    this.localStorage = new Backbone.LocalStorage("UniqueNameWithinApp", uniqueForEachInstance());
  }
  
  // ... everything else is normal.
  
});

RequireJS

Include RequireJS:

<script type="text/javascript" src="lib/require.js"></script>

RequireJS config:

require.config({
    paths: {
        jquery: "lib/jquery",
        underscore: "lib/underscore",
        backbone: "lib/backbone",
        localstorage: "lib/backbone.localStorage"
    }
});

Define your collection as a module:

define("someCollection", ["localstorage"], function() {
    var SomeCollection = Backbone.Collection.extend({
        localStorage: new Backbone.LocalStorage("SomeCollection") // Unique name within your app.
    });
  
    return new SomeCollection();
});

Require your collection:

require(["someCollection"], function(someCollection) {
  // ready to use someCollection
});

Feel free to use Backbone as you usually would, this is a drop-in replacement.
