 # Changelog

+## 2025-12-04 - 6.8.0 - feat(swdash)
+Add SW-Dash (Lit-based service worker dashboard), bundle & serve it; improve servertools and static handlers
+
+- Add a new sw-dash frontend (ts_swdash) implemented with Lit: sw-dash-app, sw-dash-overview, sw-dash-urls, sw-dash-domains, sw-dash-types, sw-dash-table, shared styles and plugin shims.
+- Wire sw-dash into build pipeline and packaging: add ts_swdash bundle to npm build script and include ts_swdash in package files.
+- Serve the dashboard bundle: add paths (swdashBundleDir / swdashBundlePath) and a built-in route (/sw-dash/bundle.js) in BuiltInRoutesController.
+- Simplify service-worker dashboard HTML output to a minimal shell that mounts <sw-dash-app> and loads the module /sw-dash/bundle.js (reduces inline HTML/CSS/JS duplication).
+- Lazy-load service worker bundle and source map in servertools.tools.serviceworker and expose /sw-typedrequest endpoints for SW typed requests (including speedtest handler).
+- Enhance compression utilities and static serving: Compressor now caches compressed results, prioritizes preferred compression methods, provides safer zlib calls, and exposes createCompressionStream; HandlerStatic gained improved path resolution, Express 5 wildcard handling and optional compression flow.
+- Improve proxy/static handler path handling to be compatible with Express 5 wildcard parameters and more robust fallback logic.
+- Deprecate Server.addTypedSocket (no-op) and document recommended SmartServe/TypedServer integration for WebSocket support.
+- Various minor packaging/path updates (paths.ts, plugins exports) to support the new dashboard and bundles.
+
+## 2025-12-04 - 6.7.0 - feat(web_serviceworker)
+Add per-resource metrics and request deduplication to service worker cache manager
+
+- Introduce per-resource tracking in metrics: ICachedResource, IDomainStats, IContentTypeStats and a resourceStats map.
+- Add MetricsCollector.recordResourceAccess(...) to record hits/misses, content-type and size; provide getters: getCachedResources, getDomainStats, getContentTypeStats and getResourceCount.
+- Reset resourceStats when metrics are reset and limit resource entries via cleanupResourceStats to avoid memory bloat.
+- Add request deduplication in CacheManager (fetchWithDeduplication) to coalesce identical concurrent fetches and a periodic safety cleanup for in-flight requests.
+- Record resource accesses on cache hit and when storing new cache entries (captures content-type and body size).
+- Expose a dashboard resources endpoint (/sw-dash/resources) served by the SW dashboard to return detailed resource data for SPA views.
+
+## 2025-12-04 - 6.6.0 - feat(web_serviceworker)
+Enable service worker dashboard speedtests via TypedSocket, expose ServiceWorker instance to dashboard, and add server-side speedtest handler
+
+- Add `serviceworker_speedtest` typed handler in TypedServer to support download/upload/latency tests from service workers
+- Export `getServiceWorkerInstance` from the web_serviceworker entrypoint so other modules (dashboard) can access the running ServiceWorker instance
+- Make ServiceWorker.typedsocket and ServiceWorker.typedrouter public to allow the dashboard to create and fire TypedSocket requests
+- Update dashboard to run latency, download and upload tests over TypedSocket instead of POSTing to /sw-typedrequest
+- Deprecate legacy servertools.Server.addTypedSocket (now a no-op) and recommend using TypedServer with SmartServe integration for WebSocket support
+
+## 2025-12-04 - 6.5.0 - feat(serviceworker)
+Add server-driven service worker cache invalidation and TypedSocket integration
+
+- TypedServer: push cache invalidation messages to service worker clients (tagged 'serviceworker') before notifying frontend clients on reload
+- Service Worker: connect to TypedServer via TypedSocket; handle 'serviceworker_cacheInvalidate' typed request to clean caches and trigger client reloads
+- Web inject: add fallback to clear caches via the Cache API when global service worker helper is not available
+- Interfaces: add IRequest_Serviceworker_CacheInvalidate typedrequest interface
+- Plugins: export typedsocket in web_serviceworker plugin surface
+- Service worker connection: retry logic and improved logging for TypedSocket connection attempts
+
+## 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
+
+- Add DashboardGenerator to serve an interactive terminal-style dashboard at /sw-dash and a metrics JSON endpoint at /sw-dash/metrics
+- Introduce request deduplication in CacheManager to coalesce concurrent network fetches and avoid duplicate requests
+- Add periodic cleanup for in-flight request tracking to prevent unbounded memory growth
+- Improve caching flow: preserve response headers (excluding cache-control headers), ensure CORS headers and Cross-Origin-Resource-Policy, and store response bodies as blobs to avoid locked stream issues
+- Provide clearer 500 error HTML responses for failed fetches to aid debugging
+- Integrate metrics and event emissions for network and cache operations (record request success/failure, cache hits/misses, and emit corresponding events)
+
 ## 2025-12-04 - 6.1.0 - feat(web_serviceworker)
 Enhance service worker subsystem: add metrics, event bus, error handling, config and caching/update improvements; make client connection & polling robust
