localForage

localForage improves what and how data can be saved offline in a browser.

It also helps broaden offline data storage usage for Web apps, by providing a single interface for working with various storage mediums, helping bring some order in various local storage tools.

By merging features and options provided by HTML5's IndexedDB, WebSQL, and localStorage, localForage can be much more useful than any of these individual tools used alone, improving data storage and data querying capabilities.

Instead of a fragmented offline storage medium, Mozilla's localForage allows developers to use an unified set of tools, with one single interface and coding patterns.

Some of the most major improvements localForage brings over individual localStorage, WebSQL, and IndexedDB usage is support for storing and retrieving multiple other data types outside strings, support for asynchronous operations, and a basic support for the Promises/A standard.
