Creating ‘Offline-First’ Applications for Wi-Fi Dead Zones

Working “in the field” or simply being out on the shop floor used to mean you were also on your own. The decisions you made and the advice you could give were based on whatever information you carried with you, whether in your head, on paper or, maybe, on some sort of digital device.

Certainly, a generation of developers has been happily creating apps with REST APIs and the cloud or remote data centers to give workers and devices out in the field — or simply walking the shop floor — the ability to share and update data, and carry out business.

Which means developers still need to consider how to sync that data back to the cloud, as well as to other devices running the app, and SQLite doesn’t include sync as standard.

So, users or devices can continue to share data locally, then, when connectivity is available, sync back to the cloud.
