Correct method to unsubscribe from WebSocket events?

[TimUnderhay]

I'm wondering: what is the correct method for unsubscribing from a WS subscription, like say wsClient.subscribeSpotKline(...params)? Thanks in advance.

This is admittedly not intuitive at the moment. The subscribe method returns a websocket object. You should be able to request closure using that ws object: wsClient.closeWs(ws):

Would be good to add this to the readme or samples.

How to unsubscribe:

// subscribe
let ws_usdm = wsClient.subscribeSymbolBookTicker('BTCUSDT', 'usdm'); 

// unsubscribe
wsClient.closeWs(ws_usdm);

you can store ws variables in array and use array to closeWs in loop
