Node.js WebSocket Server Not Broadcasting Messages to All Clients

node.js websocket broadcast JavaScript

I'm integrating two systems and I'm working with an scenario with my Node.js WebSocket server where broadcast messages are not reaching all connected clients. I'm using the `ws` library version 8.0.0 and have implemented a simple WebSocket server that accepts connections and allows clients to send messages to each other via broadcast. However, it seems that only the last connected client receives the messages. Here's a simplified version of my server code: ```javascript const WebSocket = require('ws'); const wss = new WebSocket.Server({ port: 8080 }); let clients = []; wss.on('connection', (ws) => { clients.push(ws); console.log('New client connected.'); ws.on('message', (message) => { console.log(`Received: ${message}`); clients.forEach(client => { if (client !== ws && client.readyState === WebSocket.OPEN) { client.send(message); } }); }); ws.on('close', () => { clients = clients.filter(client => client !== ws); console.log('Client disconnected.'); }); }); console.log('WebSocket server is running on ws://localhost:8080'); ``` I've confirmed that the message is received on the server side, but only the last client seems to get the broadcasted messages. I've tried logging the state of `clients` and verified that it contains all connected clients, but the scenario continues. I suspect it might be related to how I'm managing the `clients` array or the state of each WebSocket connection. Any insights on what could be going wrong or how to ensure every client receives the broadcasted messages would be greatly appreciated! How would you solve this? For reference, this is a production application. Thanks in advance!
