 # Changelog

+## 2025-12-04 - 7.4.1 - fix(web_serviceworker)
+Improve service worker persistence, metrics and caching robustness
+
+- Ensure persistent store is initialized before use in dashboard handlers and service worker activation/handlers (calls to persistentStore.init())
+- Make serveCumulativeMetrics async and align fetchEvent.respondWith usage (remove unnecessary Promise.resolve)
+- Change persistent WebStore database name to 'losslessServiceworkerPersistent' to separate durable store from runtime store
+- Make PersistentStore.init() more resilient: add detailed logging, avoid throwing on init failure, mark initialized to prevent retry loops, and start periodic save only after load
+- Ensure logEvent awaits initialization and adds defensive logging around reading/writing the event log
+- Add request deduplication logic and improved cache handling in CacheManager (fetchWithDeduplication usage and safer respondWith)
+
+## 2025-12-04 - 7.4.0 - feat(serviceworker)
+Add persistent event store, cumulative metrics and dashboard events UI for service worker observability
+
+- Add PersistentStore (ts_web_serviceworker/classes.persistentstore.ts) to persist event log and cumulative metrics with retention policy and periodic saving.
+- Introduce persistent event types and interfaces for event log and cumulative metrics (ts_interfaces/serviceworker.ts).
+- Log lifecycle, update, network and speedtest events to the persistent store (install, activate, update available/applied/error, network online/offline, speedtest started/completed/failed, cache invalidation).
+- Expose persistent-store APIs via typed handlers in the service worker backend: serviceworker_getEventLog, serviceworker_getCumulativeMetrics, serviceworker_clearEventLog, serviceworker_getEventCount.
+- Serve new dashboard endpoints from the service worker: /sw-dash/events (GET), /sw-dash/events/count (GET), /sw-dash/cumulative-metrics (GET) and DELETE /sw-dash/events to clear the log (handled in classes.cachemanager and classes.dashboard).
+- Add sw-dash events panel component (ts_swdash/sw-dash-events.ts) and integrate an Events tab into the dashboard UI (ts_swdash/sw-dash-app.ts, sw-dash-overview.ts shows 1h event count).
+- Reset cumulative metrics on cache invalidation and increment swRestartCount on PersistentStore.init().
+- Record speedtest lifecycle events (started/completed/failed) and include details in the event log.
+
+## 2025-12-04 - 7.3.0 - feat(serviceworker)
+Modernize SW dashboard UI and improve service worker backend and server tooling
+
+- Revamped sw-dash UI: new header/logo, uptime badge, live auto-refresh indicator, reorganized panels and improved speedtest UI and controls
+- Shared styles overhaul: new theming variables, spacing scale, badges, refined progress/pulse animations and cleaner typography
+- Dashboard internals: metrics endpoint and SPA shell updated; Lit bundle loading and table sort icon changed to ↑/↓
+- Service worker: added request deduplication (in-flight request coalescing), safer caching logic, consistent CORS/caching headers, and cache revalidation
+- Metrics: richer MetricsCollector with per-resource tracking, domain/content-type stats, speedtest metrics and better summary/stat helpers
+- Update & network managers: rate-limited update checks, debounced update/revalidation tasks, online/offline checks and improved retry/backoff logic
+- TypedServer & tooling: addRoute API for custom routes, improved HTML reload script injection, TypedSocket integration and a backend speedtest handler
+- servertools: improved static/proxy handlers (more robust path extraction, compression handling) and deprecation notice for addTypedSocket()
+
+## 2025-12-04 - 7.2.0 - feat(serviceworker)
+Add service worker status updates, EventBus and UI status pill for realtime observability
+
+- Introduce a status update protocol for service worker <-> clients (IStatusUpdate, IMessage_Serviceworker_StatusUpdate, IRequest_Serviceworker_GetStatus).
+- Add typedserver-statuspill Lit component to display backend/serviceworker/network status in the UI, with expand/collapse details and persistent/error states.
+- Wire ReloadChecker to use the new status pill: show network/backend/serviceworker status, handle online/offline events, and subscribe to service worker status broadcasts.
+- Extend ActionManager (client) with subscribeToStatusUpdates and getServiceWorkerStatus helpers; forward serviceworker_statusUpdate broadcasts to registered callbacks.
+- Serviceworker backend: add serviceworker_getStatus handler and broadcastStatusUpdate API; subscribe to EventBus lifecycle/network/update events to broadcast status changes to clients.
+- Add EventBus for decoupled service worker internal events (ServiceWorkerEvent enum, pub/sub API, history and convenience emitters).
+- Ensure proper subscribe/unsubscribe lifecycle (ReloadChecker stops SW subscription on stop).
+- Improve cache/connection status reporting integration so status updates include details like cacheHitRate, resourceCount and connected clients.
+
+## 2025-12-04 - 7.1.0 - feat(swdash)
+Add live speedtest progress UI to service worker dashboard
+
+- Introduce reactive speedtest state (phase, progress, elapsed) in sw-dash-overview component
+- Start a progress interval to animate overall test progress and estimate phases (latency, download, upload)
+- Dispatch 'speedtest-complete' event and show a brief complete state before resetting UI
+- Add helper methods for phase labels and elapsed time formatting
+- Add CSS for progress bar, shimmer animation and phase pulse to sw-dash-styles
+
+## 2025-12-04 - 7.0.0 - BREAKING CHANGE(serviceworker)
+Move serviceworker speedtest to time-based chunked transfers and update dashboard/server contract
+
+- Change speedtest protocol to time-based chunk transfers: new request types 'download_chunk' and 'upload_chunk' plus 'latency'. Clients should call chunk requests in a loop for the desired test duration.
+- IRequest_Serviceworker_Speedtest interface updated: request fields renamed/changed (chunkSizeKB, payload) and response no longer includes durationMs or speedMbps — server now returns bytesTransferred, timestamp, and optional payload.
+- TypedServer speedtest handler updated to support 'download_chunk' and 'upload_chunk' semantics and to return bytesTransferred/timestamp/payload only (removed server-side duration/speed calculation).
+- Dashboard runSpeedtest now performs time-based tests (TEST_DURATION_MS = 5000, CHUNK_SIZE_KB = 64) by repeatedly requesting chunks and computing throughput on the client side.
+- Documentation/comments updated to clarify new speedtest behavior and default chunk sizes.
+
+## 2025-12-04 - 6.8.1 - fix(web_serviceworker)
+Move service worker initialization to init.ts and remove exports from service worker entrypoint to avoid ESM bundle output
+
+- Remove exports from ts_web_serviceworker/index.ts so the service worker entrypoint does not export symbols (prevents tsbundle from producing ESM output).
+- Add ts_web_serviceworker/init.ts which initializes the ServiceWorker instance and exports getServiceWorkerInstance() for internal imports.
+- Update ts_web_serviceworker/classes.dashboard.ts to import getServiceWorkerInstance from init.ts instead of index.ts.
+
+## 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
