# Changelog
## 2025-12-04 - 6.4.0 - feat(serviceworker)
Add speedtest support to service worker and dashboard
- Add serviceworker_speedtest typed request handler to measure download, upload and latency
- Expose dashboard speedtest endpoint (/sw-dash/speedtest) and integrate runSpeedtest flow
- Dashboard UI: add speedtest panel, run button, visual speed bars and online indicator
- Metrics: introduce ISpeedtestMetrics and methods (recordSpeedtest, setOnlineStatus, getSpeedtestMetrics) and include speedtest data in metrics output
- Server/tools: add typedrequest handling for speedtest in sw-typedrequest and route service worker dashboard path in CacheManager
## 2025-12-04 - 6.3.0 - feat(web_serviceworker)
Add advanced service worker subsystems: cache deduplication, metrics, update & network managers, event bus and dashboard
- CacheManager: request deduplication for concurrent fetches, safer caching (preserve CORS headers), periodic in-flight cleanup and full cache cleaning API
- Fetch handling: improved handling for same-origin vs cross-origin requests, more robust 500 debug responses when upstream fetch fails
- UpdateManager: rate-limited update checks, offline grace period, debounced update and cache revalidation tasks, forceUpdate logic and persisted version/cache timestamps
- NetworkManager: online/offline detection, retry/backoff, request timeouts and more resilient makeRequest implementation
- EventBus: singleton pub/sub with history, once/onMany/onAll helpers and convenience emitters for cache/network/update events
- MetricsCollector: comprehensive metrics for cache, network, updates and connections with helper methods and JSON/HTML dashboard endpoints (/sw-dash, /sw-dash/metrics)
- ErrorHandler & ServiceWorkerError: structured error types, severity, context, history and helper APIs for consistent error reporting
- ServiceWorker & backend: improved install/activate flows, clients.claim(), cache cleaning on activation, backend APIs to purge cache and trigger reloads/notifications
- TypedServer / servertools: addRoute path pattern parsing (named params & wildcards), safer HTML injection for reload script, TypedRequest controller and service worker route helpers
- Various safety and compatibility improvements (response cloning, header normalization, cache-control decisions, and fallback behaviors)
## 2025-12-04 - 6.2.0 - feat(web_serviceworker)
Add service-worker dashboard and request deduplication; improve caching, metrics and error handling
