- Create src/lib/redis.ts (singleton client) and src/lib/cache.ts
(cachedQuery with graceful degradation on Redis failure)
- Wrap all 12 API routes and 7 RSC pages with cachedQuery (TTLs:
120s-900s by data type — dashboard 3min, inventory/orders/shipments
5min, BOL/order-ack/traveler 10min, ship-to 15min, avail-coils 2min)
- Fix redundant connection pools in dashboard.ts and shipments.ts
(were creating their own sql.connect instead of using shared pool)
- Add pool tuning to epicor.ts (max:15, min:2, 60s idle, 30s acquire)
- Parallelize session checks (getQuestSession + getActiveCompany +
isSubUser) with Promise.all across all inventory and orders pages
- Add loading.tsx skeletons for dashboard, inventory detail, orders,
and shipments pages for instant shell rendering via Next.js streaming
