WebSockets

Real-time bidirectional communication ด้วย WebSockets ใน Python

WebSocket vs HTTP

print("WebSocket vs HTTP:")
print("=" * 50)

print("""
HTTP (Request-Response):
   Client ─── Request ───> Server
   Client <── Response ─── Server
   Connection closes after response

WebSocket (Full Duplex):
   Client ─── Handshake ──> Server
   Client <══════════════> Server
   Connection stays open
   Both can send anytime

HTTP limitations:
   - Polling: inefficient
   - Long-polling: complex
   - SSE: server-to-client only

WebSocket benefits:
   - Low latency
   - Bidirectional
   - Reduced overhead
   - Real-time updates

Use cases:
   - Chat applications
   - Live notifications
   - Multiplayer games
   - Stock tickers
   - Collaborative editing
   - IoT data streaming
