How to remove socket.io EIO and other parameters from url

[minikiller]

When I configure socket-io with the following options: { url: 'ws://localhost:8888', options: {path: '/chatws', transports: ['websocket'], reconnectionAttempts: '3'}}

I get the following error WebSocket connection to 'ws://localhost:8888/chatws/?EIO=3&transport=websocket' failed: Error during WebSocket handshake: Unexpected response code: 501

If I use other frameworks that do not add any parameters then it works.

How does one remove the EIO and all query parameters from the URL?

Hi! This is unfortunately not possible, as they are part of how the library works. Could you please explain your use case?

Note: in any case, please remember that the Socket.IO client is not a WebSocket client, it will not be able to reach a plain WebSocket server
