jIO is a promise-based JavaScript library that offers connectors to many storage backends (Dropbox, webdav, IndexedDB, GDrive, ...) using a single API. jIO supports offline use, replication, encryption and synchronization as well as querying of stored documents and attachments allowing to build complex client-side centric web applications.
