How to setup routes for websocket event actions in express.js? - node.js

Question

I'm trying to create a router for every websocket event action.
Let's user is on the chat room, I want the url be ws://localhost:3001/chat but for the other event, let's say vote should be smth like this ws://localhost:3001/vote.
I found this example: const ws = new ws.Server({server:httpServer, path:"/chat"}), but this is a generic one, and doesn't aplly to different event actions.
Here is my structure. Hopefully will make more sense
As you see there I have two event actions: chat and vote and my goal is to create a route for each action types.
Socket.ts
import { IncomingMessage } from 'http';
import internal from 'stream';
import { WebSocketServer } from 'ws';
const wss = new WebSocketServer({ noServer: true });
wss.on('connection', (ws, request) => {
...
ws.on('message', (data: string) => {
try {
switch (action) {
case 'chat':
wss.clients.forEach(each(client)=> {
if (client.readyState === WebSocket.OPEN) {
client.send(JSON.stringify(message));
}
});
break;
case 'vote':
wss.clients.forEach((player) => {
if (client.readyState === WebSocket.OPEN) {
player.client.send(JSON.stringify(voteMessage));
}
});
break;
default: {
throw new Error('Unknown message type.');
}
}
} catch (error) {
ws.send(`Error: ${error.message}`);
}
});
});
const socketUpgrade = (
request: IncomingMessage,
socket: internal.Duplex,
head: Buffer
) =>
wss.handleUpgrade(request, socket, head, (ws) =>
wss.emit('connection', ws, request)
);
export { socketUpgrade };
app.ts
import express from 'express';
import { socketUpgrade } from './Socket';
const app = express();
const port = 3001;
const server = app.listen(port, () => {
console.log(`listening on port ${port}`);
});
server.on('upgrade', socketUpgrade);
Any help will be appreciated
