Couldn't agree more. I've followed this rough pattern to build a rock-solid offline-first core for a personal application: https://flpvsk.com/blog/2019-07-20-offline-first-apps-event-sourcing/ https://flpvsk.com/blog/2019-07-20-offline-first-apps-event-... It's got some pain points; in particular it's quite difficult to evolve the schema once your app is out in the wild. But event sourcing is very amenable to TDD, and once all my tests were passing I had a nearly bulletproof solution for my current schema. Strangely, offline-first functionality is usually not what event sourcing is pitched for. Maybe it's just a a legacy of its enterprise origins, but I often see it sold as a solution for enterprise applications where it's liable to cause more trouble than it's worth.
