Can I use SyncedStore solely between tabs in one browser? (No signaling servers)

See original GitHub issue

It seems like it’s possible to use SyncedStore in multiple tabs in a browser, just locally. Just BroadcastChannel and y-indexeddb, no signaling servers, and I don’t think it would need any WebRTC activity.

I can share some code I’ve tried but first I just wanted to ask the question… Is there an official way to use it purely locally?

Hi @hangtwenty.

Broadcastchannel (cross tabs) and WebRTC syncing can both be managed using y-webrtc.

I think it should be possible to disable the webrtc part in y-webrtc, and use only the broadcastchannel. Could you try to pass an empty array as signaling servers? e.g.:

new WebrtcProvider("roomname", doc, { signaling: [] })

(see https://github.com/yjs/y-webrtc/blob/c059b8679e72e4a2cd59189b022a25edbd07cbeb/src/y-webrtc.js#L545)
