Yjs IndexedDB Persistence

y-indexeddb is a database adapter for Yjs, providing robust persistence for Yjs documents directly within the browser's IndexedDB. It enables critical features such as offline editing and significantly reduces the amount of data exchanged between a server and client by storing the full document state locally. The package is actively maintained, with the current stable version being 9.0.12, and receives frequent patch and minor updates. Its primary differentiation lies in its tight integration with the Yjs ecosystem, offering reliable CRDT-based persistence for collaborative applications without requiring a separate server-side database, making it ideal for browser-based, offline-first applications leveraging Yjs.
