FetchCached

FetchCached is a dead simple drop in modification to Backbone.Collection.fetch which adds support for localStorage and sessionStorage data caching.

Usage

FetchCached overwrites Backbone.Collection.prototype.fetch so it's immediately available in all collection.fetch() method calls.

	myCollection.fetch({
		cache: {
			cache: "local",
			key: "myCollection",
			TTL: 60 * 10 // 10 minutes
		},
		success: function(collection, data) { … }
	});

If the collection.fetch method is not given a cache option, then it delegates to the original Collection.fetch method. This means all your current collection.fetch() will not be impacted :)

options

• cache - "session" or "local" (defaults to session).
• key - The cache key to store the collection under (defaults to the collection.url).
• TTL - # of seconds that the cached version is valid for (defaults to forever).
