Backbone.Safe - local storage plugin

Backbone.Safe is a plugin for Backbone.js which stores a model's or a collection's json data to the local storage on set operations, regardless server side existance. The concept for Backbone.Safe has been created while the developing the Echoes Player project.

Install

Using Bower:

bower install backbone.safe

Usage

The latest update to Backbone.Safe allows one to define safe with a non distructive definition using a key as such:

varUserProfile=Backbone.Model.extend({safe: {key: 'myAppUserSafe',reload: false},initialize: function(){// some statements;this.safe.reload()},fetchRoles: function(){// some statements;}});varuser=newUserProfile();console.log(user.safe);

With this method, when Safe is not present, the model/collection still functions as expected.

On the other hand, Safe can defined using a factory method as such:

varHistoryPlaylist=Backbone.Collection.extend({model: someModel,initialize: function(){Backbone.Safe.create('historyPlaylist',this);},queue: function(youtubeJSON){this.add(youtubeJSON);}});varmyPlaylist=newHistoryPlaylist();console.log(myPlaylist.safe);

Useful Information

1. Currently supports only one level of models/collections.
2. For Model: listens to a 'change' events and stores the data.
3. For Collection: listens to 'add', 'reset' events and stores data.
4. The 'create' function creates a new instance of Backbone.Safe in the 'safe' property
