WebSocket is a protocol enabling full-duplex communication between a client and server over a single TCP connection. Unlike traditional HTTP, which requires repeated handshakes for each request, WebSocket establishes a persistent connection once, allowing real-time data exchange. ✅
Key Features
- Low Latency: Ideal for applications requiring instant updates (e.g., chat apps, live dashboards)
- Bidirectional Data Flow: Both client and server can send messages independently
- Efficient Resource Usage: Reduces overhead compared to HTTP polling
- Support for Binary Data: Handles both text and binary payloads
Use Cases
- Real-time multiplayer games 🎮
- Live financial data streaming 💰
- Collaborative editing tools 📝
- IoT device communication 🌐
