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.

From Mobile First to Offline First
Web Browsers as Thin Clients
Chaos of Web
The Eight Fallacies of Distributed Computing
1. The network is reliable
2. Latency is zero
3. Bandwidth is infinite
4. The network is secure
5. Topology doesn't change
6. There is one administrator
7. Transport cost is zero
8. The network is homogeneous
Lack of connectivity is
not an error condition.
One Database Per User
A CouchDB proxy to enable replication of database subsets
We took the Offline First community for three day retreats in the Catskill
Mountains and in California to help foster the growing Offline First movement
