A VERY basic chrome.storage.local custom sync, method for Backbone.js Models

gistfile1.js

	

var createLocalStorageSync = function(storageKey)
	{
		return function(method, model, options) 
		{
			switch (method) 
			{
				case 'create':
				case 'update':
					chrome.storage.local.set({storageKey: JSON.stringify(model) }, options.success );					
				break;
				case 'delete':
					chrome.storage.local.remove(storageKey, options.success );
				break;
				case 'read':

					chrome.storage.local.get(storageKey, function(items)
					{
						options.success( items[storageKey] && JSON.parse(items[storageKey]) || {} );
					});

				break;
			}

			return this;
		};
	};


// usage

SettingsModel = Backbone.Model.extend
	({
// override sync with the custom sync method, and declare a key to be used when saving to localStorage
		sync: createLocalStorageSync('settings'),
		defaults:
		{
			'notifications-onmessage': true
		}
	});


This DOES NOT work on collections.
