Connect to an other socket.io server

[ghost]

Hello, I would like to know if there is a way to disconnect from a socket.io server and connect to an other with a new ip/domain without losing socket listeners ?

Hi! You should be able to update the Manager uri attribute:

import { io } from "socket.io-client";

const socket = io("https://my-domain-a.com");

socket.io.uri = "https://my-domain-b.com";

// force reconnection
socket.disconnect().connect();

The TypeScript compiler might complain though, as it's a private readonly attribute.

This is super helpful, I just want to note for anyone else doing this, I don't think setting a new uri will update the namespace.

In my case I was initializing io without passing any uri, which caused it to use the currrent URL, and incorrectly use a namespace like //capacitor://localhost even after I updated the uri to something like https://example.com using this method. I ended up initializing it with a dummy uri so it doesn't try to use the current URL and a non-default namespace.
