How to implement guide with node.js and websocket connection dropping after 60 seconds
I keep running into I'm deploying to production and I'm running a Node.js server using the `ws` library for WebSocket communication, and I've encountered an scenario where the connection drops after approximately 60 seconds of inactivity. I'm using Node.js version 14.17.0 and the `ws` library version 7.5.1. I've checked my server code and the client implementation, but I need to seem to find the source of the question. Here's a simplified version of my server code: ```javascript const WebSocket = require('ws'); const server = new WebSocket.Server({ port: 8080 }); server.on('connection', (ws) => { console.log('Client connected'); ws.on('message', (message) => { console.log(`Received: ${message}`); }); ws.on('close', () => { console.log('Connection closed'); }); }); console.log('WebSocket server is listening on ws://localhost:8080'); ``` On the client side, I'm using a basic WebSocket connection like this: ```javascript const socket = new WebSocket('ws://localhost:8080'); socket.onopen = () => { console.log('WebSocket connection established'); }; socket.onmessage = (event) => { console.log(`Message from server: ${event.data}`); }; socket.onclose = () => { console.log('WebSocket connection closed'); }; setInterval(() => { socket.send('ping'); }, 30000); // Send a ping every 30 seconds ``` I've added a keep-alive mechanism to send a ping message every 30 seconds, but the connection still drops after a minute. I’ve checked my network settings and ensured that there are no firewall rules that could be interrupting the connection. The behavior messages in the console indicate that the client is getting a `CLOSE` event, but there are no errors on the server side. Does anyone have insights into why the WebSocket connection might be dropping after 60 seconds despite the keep-alive pings? Any suggestions for debugging this scenario or changes to the configuration would be greatly appreciated. My development environment is Windows 10. Any pointers in the right direction?
