Questions tagged [localforage]

Mozilla's asynchronous offline storage.

localForage is a JavaScript library that improves the offline experience of your web app by using asynchronous storage (via IndexedDB or WebSQL where available) with a simple, localStorage-like API.

localForage uses localStorage in browsers with no IndexedDB or WebSQL support. Asynchronous storage is available in the current versions of all major browsers: Chrome, Firefox, IE, and Safari (including Safari Mobile). See below for detailed compatibility info.
