This article is about engineering an offline-first app for low-end devices based on our experience in Nigeria and India. The interesting problems in this space are storage, quota, cold start, and failure-path design. Our approach applies to any product whose users are on constrained devices and intermittent connections, when the assumption they have a laptop and broadband access do not hold. By Chidi Nwaogu
Cloudflare has put Quicksilver, the internal key-value store behind nearly every request it serves, into private beta as a Workers KV mode.
