Any events on websocket-client disconnect?

[a-marchenko]

I need to know that the client (nats.ws) has disconnected without constantly polling all clients every few seconds.
I'm wondering if there are some NATS events that I could subscribe to in other services?
Or how do I need to modify the nats-server code in order to timely learn about the broken connection to the websocket client?

Are you listening for disconnect events?

You ask for NATS event, so probably this one is what you are looking for
