Websocket Implementation

This handles the full WebSocket stack from connection management to horizontal scaling with Redis adapters. You get reference implementations for Socket.IO servers, browser clients, Python with aiohttp, plus message protocols and room-based routing. The examples are production-minded, covering reconnection logic, rate limiting, and cleaning up dead connections. If you're building chat, live notifications, or collaborative features and need more than a basic tutorial, this gives you the patterns for handling thousands of concurrent connections without the common pitfalls. The best practices section is honest about what breaks at scale, like keeping unlimited history in memory or ignoring authentication.
