Hook — Sell Even When the Grid Doesn't
In 2026, the difference between a missed sale and a loyal customer is often network resilience. Offline‑first PWAs let agora sellers collect payments, record inventory and deliver promotions without full connectivity.
Key features for seller PWAs
- Offline cart persistence and queued sync.
- On‑device coupons and cached promotions.
- Compact asset footprints to reduce cold start times.
Architecture notes
Use a cache‑first service worker strategy for product assets, and an incremental sync for orders to avoid conflicts. Tie local ads to on‑device inference for personalized upsells with privacy preserved.
