Currently any additional data transformation is left to the developers to extend via event hooks or custom client side handling.
I've worked with CRDT in the past (yjs), but it may not be very useful in PocketBase considering that the application was designed to run on a single server and db writes are practically queued (you can have only one sqlite writer at a time). I'll investigate it further and may consider it for future release.
I think if you integrate Yjs or a OT library first-party, you'll have a really exceptional framework - open source firebase alternative top-to-bottom, ready for "local-first" collaborate own-your-own-data apps. Sounds like my dream stack for small-scale projects or friend/family apps.
