yjs-sync

You can sync Yjs CRDT documents across clients in real time using a provider that manages SSE or long-poll streaming, authentication headers, and automatic reconnection over durable streams to ensure consistent collaborative editing states.

Handling authentication for Yjs collaborative editing streams is done by supplying static tokens or dynamic functions that refresh per request, enabling seamless credential rotation while generating custom headers for each streaming connection.

Yes, you can use SSE and long-polling for Yjs real-time synchronization on mobile applications, as the provider supports both live streaming modes to accommodate different network environments and platform constraints.

The connection state machine handles Yjs network errors and reconnections through automatic transitions between disconnected, connecting, and connected states, providing built-in retries for server errors and snapshot discovery failures while emitting clear status events.

You need a custom provider to manage Yjs document lifecycle and error recovery because manually implementing connection state machines, retries, and snapshot discovery leads to duplicated code, fragile reconnection logic, and inconsistent client states.

You integrate Yjs sync status events with UI frameworks like React by using the event-driven API to listen for synced, status, and error events, allowing your components to react dynamically to real-time connection lifecycle changes.
