fridge: Offline Data Storage. Stores Anything, Everywhere

Description:

fridge is the World’s lightest multi-backend offline web storage JavaScript library on the planet. It uses localStorage, indexedDB, and webSQL backends as key-value store database to store data locally in the web browser. It wraps all of them using a fast, cross-browser localStorage-like API and stores a very wide range of data types in the most optimal way possible, everywhere.

It uses all the available web storage backends. If one is full, it automatically stores in another.
