Backbone localStorage Adapter v1.1.16

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({
  
  localStorage: new Backbone.LocalStorage("SomeCollection"), // Unique name within your app.
  
  // ... everything else is normal.
  
});

If needed, you can use the default Backbone.sync (instead of local storage) by passing the ajaxSync option flag to any Backbone AJAX function, for example:

var myModel = new SomeModel();
myModel.fetch({ ajaxSync: true });
myModel.save({ new: "value" }, { ajaxSync: true });

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 SomeCollection;
});

Require your collection:

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

CommonJS

If you're using browserify.

Install using npm install backbone.localstorage, and require the module.

Backbone.LocalStorage = require("backbone.localstorage");
