Also some more pondering on local-first application development from a "few" (~10) years back can be found here: https://unhosted.org/

Sync Engines Are the Future
The author would be excited to learn that CouchDB solves this problem since 20 years.
The use case the article describes is exactly the idea behind CouchDB: a database that is at the same time the server, and that's made to be synced with the client.
You can even put your frontend code into it and it will happily serve it (aka CouchApp).

Fsync() after open() is an elaborate no-op
AFAIK, this is the norm and, I assume, the reason that the NULL BITMAP article [3] suggests the fsync on open. In CouchDB land, we just went back and said, "Oh nice, we already do that for other reasons anyway." Unfortunately the "we already do it for other reasons" aspect didn't really come through. So in the end, while none of the behavior on fsync-on-open is guaranteed in anyway shape or form, it's not impossible that it's saved our bacon a non-zero number of times. Just because its not guaranteed, its common that filesystems will in fact perform those flushes regardless of which file descriptor is used.
Also, to make sure that we're not missing the field for the cornstalks, I want to point out that the double fsync commit protocol used by CouchDB is probably 99.some-more-nines responsible for CouchDB's durability guarantees. However, that's not 100%, so when we find weird edge cases like in [3] we try and make sure that we're as correct as can be. For instance, here's the response to fsync-gate [4].

MongoDB takes a swing at PostgreSQL after claiming wins against rival
If you like the document db idea there are a lot of choices, especially

which I think gets little attention because people who use it see it as a secret weapon. Too bad about the license though. Also
