XMPP Connector for Yjs

XMPP is a very nice choice as a Connector, because it provides already a lot of functionality.

• Can act as a Connector for thousands of users
• Sophisticated Rights Management
• Federated
• Works with nodejs and in the browser

In production, you may want to implement a master instance (in Node.js), that holds the state of your shared data types, even when all users are disconnected. You can find such a server implementation here. Note: Yjs itself does not depend on a server instance. The server implementation is just another client in the XMPP chat room. Also: Having (a) master client(s) in the chatroom, can reduce traffic significantly.

Use it!

  }
  // types: ['Richtext', 'Array'] // optional list of types you want to import
}).then(function (y) {
  // bind the textarea to a shared text element
  y.share.textarea.bind(document.getElementById('textfield'))
}
