Broadcasting Messages to Clients
Learn how to send messages from the server to all connected clients or specific ones.
What is Broadcasting?
Realtime applications often need to send updates to many users at once. Imagine a live sports score or a chat room.
Broadcasting is when your server sends a single message that is delivered to all currently connected clients.
Why Broadcast Messages?
Broadcasting is a fundamental pattern for many interactive applications:
- Live Updates: Stock prices, news alerts, sensor data.
- Chat Rooms: New messages visible to all participants.
- Notifications: System-wide alerts to all active users.
- Multiplayer Games: Player movements, game state changes for all players.
