From Mobile First to Offline First at ConFoo Montreal

Offline First is an approach to application design in which a web, mobile, desktop, or Internet of Things application is built for offline usage first and is then progressively enhanced to take advantage of network connectivity when available. An Offline First app can provide a better, faster user experience — both offline and online — by storing content and data locally and synchronizing with the cloud when a network connection is available.
