Three UX wins so the app feels "already loaded" the moment it opens:
1. IndexedDB React Query persistence (lib/queryPersister.ts)
- PersistQueryClientProvider rehydrates the last-seen spots, shops,
events, tours, crews, coaches, listings and author profiles from
IndexedDB on cold start, so returning users land on a populated map
instead of a blank one; fresh data refetches quietly in the
background.
- Strict allow-list / deny-list: only public, JSON-serializable,
cold-start-relevant queries are persisted. Private/encrypted data
(stash, DMs, contacts, wallet/nwc/cashu/bitcoin, signer) is NEVER
written to disk. 24h maxAge + version buster keep it fresh & safe.
- Pinned @tanstack/react-query + query-core + persist-client to a
single 5.102.8 to avoid a query-core mismatch (partialMatchKey).
2. Optimistic geolocation (lib/lastLocation.ts)
- getCurrentPosition now caches every successful fix.
- The map opens ALREADY centered on the user's last-known area
(city zoom) instead of the world view; "you are here" + proximity
sort seed from the cache instantly.
- "Near Me" flies to the cached location immediately on tap, then
refines to the fresh GPS fix. Silent background warm-up on web map
mount so a later tap resolves instantly.
3. Cold-start skeleton (components/MapSkeletonPins.tsx)
- When the map is genuinely empty + loading, show elegant pulsing
ghost pins + a "Finding spots" pill instead of a blank map; they
vanish the instant real (or cached) spots render. Splash now
signals content-ready when spots actually resolve.
Respects prefers-reduced-motion throughout. Build + runtime verified
clean (no console errors).
