need help refreshing websocket

We currently are using tRPC w/ react and websockets. We’re using the URL of the websocket as the auth token to the websocket I.e. ws://localhost?token=12345 We want to be able to kill this websocket connection and reopen one with a new token, I.e. ws://localhost?token=12346 I’ve tried putting the trpcClient in react state, but when the state updates the old websocket connections stay open. I’ve also tried setting the URL with a function, and manually killing the websocket, and letting the WS automatically reconnect, but there’s no way to manually kill the websocket from the client Does anyone have advice or could like a pattern maybe where the websocket url has to dynamically change. (Or has a better way to continually authenticate a websocket connection)

Thanks in advance for any help!!!

Pretty sure if you close the websocket connection it will reopen it So you could use that as a side effect when your access code changes

Following this as I'm having the same issue @twelventi - did you figure this out yet?

@itsnotyalc I believe when you create a wslink, and a ws client, you can pass a function to the url parameter which can dynamically return a URL, but we ended up not going with a pattern that required a new url for the websocket everytime so I’m not sure if that works I.e.

createWsClient({
    url: () => dynamicFunctionToGetUrl()
})

createWsClient({
    url: () => dynamicFunctionToGetUrl()
})

Do you mind sharing that pattern? I just tried this approach out but no dice

We pass a session token to the websocket that is basically a lookup in a diff place to see if that session is still active Then re-authenticating keeps that same session ID alive

Hmm, okay. Appreciate the response!
