jubnl	bcd2c8c959	fix(repo): fall back to Dexie when a network read fails (H2) (#1179) ... Repos gated reads on raw navigator.onLine and the online branch had no try/catch, so a captive portal or connected-but-no-internet (navigator.onLine lying "true") threw a network error instead of serving the good cached copy — blanking the trip even though Dexie held it. - new onlineThenCache(onlineFn, cacheFn) helper: reads the cache when offline, and on a network-level failure (Axios error with no HTTP response). A genuine HTTP error (4xx/5xx — the server responded) is rethrown so callers still set error state / navigate, not masked by a stale cache. - gates only on navigator.onLine, NOT the connectivity probe: the probe is a coarse global flag and one failed health check would otherwise divert every read to the (possibly empty) cache even when the request would succeed. - every repo list/get read path routed through it (reads only — writes still go through the mutation queue so failures surface) - tests: captive-portal fallback, HTTP-error rethrow, non-Axios rethrow	2026-06-15 09:25:11 +02:00
jubnl	b194e8317d	feat(pwa): implement real offline mode with IndexedDB sync ... Add genuine offline read/write capability for trips: - Dexie IndexedDB schema (trips, places, packing, todo, budget, reservations, files, mutationQueue, syncMeta, blobCache) - Repo layer for all domains: offline reads from Dexie, writes optimistically to Dexie and enqueue mutations for later replay - Mutation queue with UUID idempotency keys (X-Idempotency-Key), FIFO flush, temp-ID reconciliation on 2xx, fail-and-continue on 4xx - Trip sync manager: caches all trips with end_date >= today or null, auto-evicts 7d after end_date, fetches bundle endpoint in one request - Map tile prefetcher: bbox from place coords, zooms 10-16, 50MB cap, warms SW cache via fetch - Sync triggers: network online → flush + syncAll; WS reconnect → flush only (rate-limiter safe); visibilitychange/30s → flush only - WS remoteEventHandler writes through to Dexie on every event - Server idempotency middleware + idempotency_keys table (migration 100, 24h TTL nightly cleanup) - GET /api/trips/:id/bundle endpoint for efficient single-request sync - OfflineBanner component: amber (offline) / blue (syncing) / hidden - OfflineTab in Settings: cached trip list, re-sync and clear actions - usePendingMutations hook for per-item pending indicators Closes #505 #541	2026-04-14 23:04:25 +02:00
