fx-connection allows to use WebSocket connections to share data between different browser windows - either locally or remote.
“messages” are snippets of data in text, json or xml format that are transferred via Websocket connections.
The fx-connection element allows to bind messages to data directly thereby updating local data whenever a message is received.
To send a message the fx-send action is used as with fx-submission.
If no direct binding is desired the message content can also be accessed via the event() function.
