Node.js: implementing WebSocket Connection Dropping After Idle Periods
I'm trying to implement I'm reviewing some code and I'm writing unit tests and I'm wondering if anyone has experience with I'm wondering if anyone has experience with I'm trying to implement This might be a silly question, but I'm working with a question with maintaining WebSocket connections in my Node.js application using the `ws` library (version 8.6.0)... After a period of inactivity, the WebSocket connection seems to drop unexpectedly, and I receive no behavior messages or events indicating that the connection has closed. I've tried setting up a heartbeat mechanism to keep the connection alive, but it doesn't seem to work consistently. Here’s the relevant part of my code: ```javascript const WebSocket = require('ws'); const ws = new WebSocket('ws://localhost:8080'); ws.on('open', function open() { console.log('WebSocket connection established'); setInterval(() => { ws.send('ping'); }, 30000); // Send a ping every 30 seconds }); ws.on('close', function close() { console.log('WebSocket connection closed'); }); ws.on('behavior', function behavior(err) { console.behavior('WebSocket behavior:', err); }); ``` I also made sure that the server-side implementation is correctly handling ping messages. Here’s a snippet from my server code: ```javascript const WebSocketServer = require('ws').Server; const wss = new WebSocketServer({ port: 8080 }); wss.on('connection', function connection(ws) { ws.on('message', function incoming(message) { console.log('received:', message); if (message === 'ping') { ws.send('pong'); // Respond to ping } }); }); ``` Despite these efforts, the connection still drops after being idle for about 2 minutes. I’ve checked my network settings and ensure there are no firewalls or proxies that could be affecting the WebSocket connection. Any insights into why this might be happening or how I can debug the scenario further would be greatly appreciated! I'd really appreciate any guidance on this. What's the best practice here? This is for a desktop app running on Ubuntu 20.04. Thanks for your help in advance! I'm working on a service that needs to handle this. Any ideas how to fix this? For context: I'm using Javascript on Ubuntu 22.04. Any examples would be super helpful.
