how to organize socket handling in node.js and socket.io app

For my REST api I have create a file for each route.

app.get('/api/user', routes.user.index);
app.get('/api/user/login', routes.user.login);

etc, etc.

Now I'm introducing socket.io to the backend and it seems I can only call one function for all socket events.

var socket = require('./socket/stuff.js');

io.sockets.on('connection', function(sock){
    socket.stuff(sock, io);
});

How should I break up the ./socket/stuff.js file (which exports stuff). Into separate files. I would like to eventually replace my REST api with sockets, but I don't want everything to be in one file.

I imagine I would have:

./socket/chat.js
./socket/user.js

etc. etc.

index.js

const httpServer = require("http").createServer();
const io = require("socket.io")(httpServer);

const registerOrderHandlers = require("./orderHandler");
const registerUserHandlers = require("./userHandler");

const onConnection = (socket) => {
  registerOrderHandlers(io, socket);
  registerUserHandlers(io, socket);
}

io.on("connection", onConnection);

orderHandler.js

module.exports = (io, socket) => {  const createOrder = (payload) => {    // ...  }
  const readOrder = (orderId, callback) => {    // ...  }
  socket.on("order:create", createOrder);  socket.on("order:read", readOrder);}

I got it from the documentation. https://socket.io/docs/v4/server-application-structure/
