Socket.io: How to change server options on runtime

[Sarathmunusamy93]

Hi Team,

Currently I am using Socket.io connection in my application. Below is my server socket.io code.

const SocketOptions = { pingTimeout: 60000, maxHttpBufferSize: 1024 *XXX*XXX transports: [ "polling", "websocket"] }
const io = socket.io( MY_SERVER, SocketOptions )

Currently, I need to set "path" of the server option on runtime means dynamically. My question is below.

1. Is changing socket.io server options is valid?
2. If yes How to do it?

I would be helpful if anyone help me to solve this.

Thanks in advance.

Hi! You can use the path() method:

import { Server } from "socket.io";

const io = new Server(3000);

io.path("/myownpath/");

Reference: https://socket.io/docs/v4/server-api/#serverpathvalue

For the other options, you may need to update the opts attribute of the underlying engine, for example:

io.engine.opts.maxHttpBufferSize = 1e8;
