It's astonishing to me how difficult it (still) is to design a syncable local-first data model.
I keep thinking I've found a decent way, then realizing its flaws, then despondently noticing that the flaws were already discussed in Ink & Switch's article: inkandswitch.com/local-first.ht

It’s really difficult. I’ve had success applying event sourcing to the problem, but schema evolution is a pain and it means my data model takes up a lot of my complexity budget

At least for me, the one saving grace is that this is very amenable to TDD and testing in general; easy+fast to replay events and then verify the final state

Yeah, that definitely helps, makes me feel much more comfortable.
