MongoDB Persistence Provider for Yjs

y-mongodb-provider is a database adapter that enables persistent storage and retrieval of Yjs collaborative documents using MongoDB. It serves as a backend for y-websocket servers, allowing Yjs document states to be saved and loaded, thereby ensuring data durability across server restarts or disconnections. The current stable version is 0.2.1, with updates primarily focused on dependency management, internal driver improvements, and bug fixes, indicating an active development status though without a strict release cadence. Key differentiators include its specific integration with MongoDB (unlike Yjs's officially supported y-leveldb), its ability to handle Yjs updates exceeding MongoDB's 16MB document size limit (since v0.1.8), and its use of the official MongoDB Node.js Driver for enhanced security and performance. It's important to note that this package is not officially supported by the Yjs team.
