FAQPage Schema
How do I set up a Yjs WebSocket server for real-time collaborative editing?▼

To set up a Yjs WebSocket server for real-time collaborative editing, configure a Node.js environment to run the server logic on a designated port, enabling CRDT synchronization across multiple connected clients.

Can I use LevelDB or the file system for Yjs server data persistence?▼

Yes, you can use LevelDB or the file system for Yjs server data persistence. The server supports integrating these storage options to ensure data durability for synchronized CRDT documents across sessions.

How does the Yjs awareness protocol handle user presence and cursors?▼

The Yjs awareness protocol handles user presence and cursors by broadcasting lightweight client state updates over the WebSocket connection, allowing connected users to see live selections and cursor positions.

Do I need JWT to secure a real-time Yjs collaboration server?▼

You do not strictly need JWT, but it is a supported method to secure a real-time Yjs collaboration server. You can implement JWT or other custom authentication methods to protect WebSocket connections.
