Manipulate the URL

[Tockra]

Hi folks,

I've the problem that my websocket endpoint needs authentication.
The first approach was to send a Authorization header field with the bearer token like ALL my endpoints expect.
But I found no websocket client for javascript providing a custom header field.
So I changed to queryParameter. So my URL contains ws://<baseURL>/<path>?token=<access_token> .

Now I ran into the next problem. If I lose the connection to my websocket for longer than 5 minutes, then the access_token stored in the initial URL will be invalid. In this case the re-connect logic results in a infinite loop.

So I would like to adjust the websockets URL in case my auth.access_token changes.
Is there currently a mechanism allowing that?

Otherwise I have to kill my websocket connection each 5 minutes and restore it. This would no so cool.

I think you can listen to the "close" event to check the token. If the token is invalid, force close and reconnect.

In addition, if you want to use custom headers in the websocket connection, you can do it by customizing the Websocket class, for example:

function customWebSocketWithHeaders(headers)
  class MyWebSocket extends WebSocket {
    constructor(url, protocols) {
      super(url, protocols, { headers });
    }
  }
  return MyWebSocket;
}

const rws = new ReconnectingWebSocket(wsUrl, [], {
  WebSocket: customWebSocketWithHeaders({ your_header: 'value'}),
})

I have the same issue. Im my case, the backend put token into url query params and I need to fit this unchangeable decision =(. Finally, I patch the reconnecting-websocket package. Modify the url from string to a promise function to fit my case.
