From "SQLedge: Replicate Postgres to SQLite on the Edge" (2023) https://news.ycombinator.com/item?id=37063238#37067980 :
>> In technical terms: cr-sqlite adds multi-master replication and partition tolerance to SQLite via conflict free replicated data types (CRDTs) and/or causally ordered event logs
In Automerge: A library of data structures for building collaborative applicationsWhat does "scale" here mean? Sqlite can go quite far https://use.expensify.com/blog/scaling-sqlite-to-4m-qps-on-a...
I agree with you w/r/t "Why build your own query builder" though since (AFAIK) you can't touch the underlying SQL. I'm making heavy usage of FTS5 in my app, and it doesn't look like they support that.
And, to be fair, feathers/rethink also have the weaknesses you list:
- Why build your own query builder
- This also isn't really something you could drop into an existing project very easily
Personally, I've been pretty happy with https://github.com/vlcn-io/cr-sqlite/ which is just a sqlite extension that can run in the browser.
In Show HN: Triplit – Open-source syncing database that runs on server and clientHow does this compare to cr-sqlite (https://github.com/vlcn-io/cr-sqlite) which uses CRDTs to create a conflict free replicated sqlite?
In SQLSync: A collaborative offline-first wrapper around SQLiteIs your "recall probability estimating algorithm" similar to FSRS's retrievability?

If you ever feel like moving beyond the Apple market you might look into https://github.com/vlcn-io/cr-sqlite I've been using it in my own Anki-clone and am very happy with it.
In Show HN: Flash Notes – Flashcards for Your Notes, LLM, iOS/macOS SyncHey, after I posted that, I went and gave a second look online to see if I could find something that would allow me to develop a local-first app with offline persistence and syncing capabilities.
I ended up finding some possibilities out there that could potentially help me build stuff. One of them is RxDB [1], which offers WebRTC syncing - you'd still need a signaling server, I suppose, but all sensitive information could be synced E2E-encrypted via WebRTC.
Then there's CRDT's [2], which is a universe that turned out to have multiple possibilities that match (at least partially) my needs. In particular, the next thing I want to take a look at is cr-sqlite [3], which might be just thing I needed to kick-off some side-projects.
I'm posting here cause I just found some hope of not needing to build a traditional client-server app and having

to deal with all the hassle involved in securing a server (and with fear that my efforts could be not good enough), and I thought someone else could benefit from getting to know these things.
