localForage

localForage is a fast and simple offline storage library that provides an asynchronous, localStorage-like API using IndexedDB, WebSQL, or localStorage as fallback. Current stable version is 1.10.0, with maintenance-level updates. It simplifies client-side storage by automatically selecting the best available backend and supporting promises, callbacks, and async/await. Key differentiator: works with all modern browsers, handles Blobs and TypedArrays, and has a tiny footprint (~1.2KB gzipped).
