node.js socket.io express JavaScript

I'm relatively new to this, so bear with me. I'm trying to figure out I'm following best practices but After trying multiple solutions online, I still can't figure this out... I'm relatively new to this, so bear with me. Currently developing a real-time chat application using Node.js with Express and Socket.IO. The basic setup works well, allowing users to connect and exchange messages. However, I'm facing intermittent connection drops that seem to occur randomly after a few minutes of active use. The server logs show messages like 'Socket connection closed', and the client experiences a loss of connection without any apparent reason. Here’s a simplified version of the code I’m using: ```javascript const express = require('express'); const http = require('http'); const socketIo = require('socket.io'); const app = express(); const server = http.createServer(app); const io = socketIo(server); io.on('connection', (socket) => { console.log('New client connected'); socket.on('disconnect', () => { console.log('Client disconnected'); }); }); server.listen(3000, () => { console.log('Listening on port 3000'); }); ``` To troubleshoot this, I've tried increasing the `pingTimeout` and `pingInterval` settings in Socket.IO, thinking that it might help maintain the connection: ```javascript const io = socketIo(server, { pingTimeout: 60000, pingInterval: 25000 }); ``` Despite these adjustments, the issues persist. Also, I’ve ensured that the server and client are both updated to the latest version of Socket.IO (4.0.0). I've tested the application in various network conditions and found that the drops happen more frequently on slower connections. I suspect it might be a configuration issue or possibly related to how I'm handling session management on the server. Any insights on how to maintain a stable WebSocket connection or diagnose potential pitfalls would be greatly appreciated. Also, is there a recommended practice for handling reconnections gracefully on the client side when this happens? For context: I'm using Javascript on Linux. I'd really appreciate any guidance on this. I've been using Javascript for about a year now. Any advice would be much appreciated. Thanks for taking the time to read this! Hoping someone can shed some light on this. I'm working on a desktop app that needs to handle this. Thanks, I really appreciate it!
