websocket-demo

A simple WebSocket server built with the ws library that broadcasts messages to all connected clients in real time.

How It Works

The server listens on ws://localhost:8080. When a client connects and sends a message, the server broadcasts it to every connected client (including the sender) prefixed with Server Broadcast:.

Running the Server

npm run dev

This uses node --watch server.js which auto-restarts the server on file changes.

Connecting a Client with wscat

Install wscat globally if you don't have it:

npm install -g wscat

Connect to the server:

wscat -c ws://localhost:8080

Once connected, type a message and press Enter. Every connected client will see the broadcasted message in real time. Open multiple terminals with wscat to see multi-client messaging live.
