Yjs is a framework for offline-first p2p shared editing on structured data like text, richtext, json, or XML.
|
||||
It is fairly easy to get started, as Yjs hides most of the complexity of concurrent editing.
|
||||
For additional information, demos, and tutorials visit [y-js.org](http://y-js.org/).

* Set `options.connector.generateUserId = true` in order to genenerate a userid, instead of receiving one from the server. This way the `Y(..)` is immediately going to be resolved, without waiting for any confirmation from the server. Use with caution.
