…cs, and WebSocket upgrade detection on shared port Implement an HTTP server as the primary listener using Node.js built-in http module, with WebSocketServer running in noServer: true mode. Incoming requests are inspected for the Upgrade header to correctly route WebSocket upgrades vs plain HTTP requests. Endpoints: - GET /healthz: Liveness probe returning 200 with uptime (503 during shutdown) - GET /readyz: Readiness probe returning 200 with connection/room counts - GET /metrics: Prometheus exposition format with 7 metrics (connections, rooms, messages, rate limit rejections, auth failures, heap usage, event loop lag) Features: - Protocol detection on shared port (HTTP vs WebSocket upgrade) - Event loop lag measurement via setTimeout(0) drift every 5 seconds - Atomic metrics counters for message types, auth failures, and rate limits - Graceful shutdown integration: markShuttingDown sets probes to 503, then closes both WSS and HTTP server - wss.address() patched to return httpServer.address() for test compatibility Closes #199
feat: Co-located HTTP server with health checks, Prometheus metrics, and WebSocket upgrade detection (#199)
…ain queues - Add backpressure options to RoomManager constructor (opt-in) - Batch broadcasts using setImmediate to prevent event loop starvation - Detect slow consumers via ws.bufferedAmount high water mark - Coalesce location_update messages for slow consumers - Auto-terminate slow consumers after configurable timeout - Add getRoomStats() for observability (queue depths, slow consumers) - Clean up slow consumer state on disconnect (no memory leaks) - All existing tests pass unchanged (backward compatible) Closes #734 Closes #733
- Remove duplicate wss and httpServer declarations causing SyntaxError
- Merge two scrambled implementations into single coherent createServer
- Add /health and /healthz endpoints returning JSON responses
- Add /readyz readiness endpoint with connection/room counts
- Add /metrics Prometheus endpoint tracking connections, messages, auth
- Add markShuttingDown() for graceful shutdown support
- Restore safeSend wrapper for error-safe WebSocket sends
- Restore per-message rate limiting via createRateLimiter import
- Fix clearInterval referencing undefined 'interval' variable
- Add per-IP connection count tracking with configurable max
- Return { wss, httpServer, rooms, markShuttingDown }
- All 178 tests pass, lint clean
Closes #191
