Working with @rxdbjs and feeling a blast. Tried @convex, but i'm still a @supabase fan too much to drop it. Looked at @ElectricSQL and @tan_stack db, and it's meaning good, but requires hosting, adding more complexity, plus does feel quite ready. But RxDb is fire.

A hill I’ll run to the top to die on is that FRP really is the right way to do UI (and note to self to return to my little side project to integrate <react-rxjs.org/> and <rxdb.info/>).
idk if i can make this coherent but i feel like a lot of ui problems are really concurrency problems and a lot of the awkwardness of ui development is cuz you need good transactional semantics

TanStack Start is a new full-stack framework for React that's an alternative to options like Next.js and Remix. And in this tutorial, @andrewbaisden walks you through how to get started with it. You'll use it to build a CRUD app along with TanStackDB and add RxDB integration, too. freecodecamp.org/news/how-to…

If you build with TanStack DB, you can swap out and optimise your state transfer layer without affecting your application code. Migrate from query to sync. Still query when you need to. Integrate external services into a unified client-side data model. Swap out one sync engine for another.
TanStack DB now has a @rxdbjs collection! Thanks to RXDB's creator @pubkeypubkey for building it!

Offline data synchronization for an app is no longer a luxury, but a necessity. Therefore, we’re happy to announce that Appwrite Databases now features a direct integration with @rxdbjs , a local-first NoSQL database designed for JavaScript apps. Now, it's easier than ever to build real-world apps that stay in sync online and offline. Not sure where to start? We've got you covered. We've built an offline-first journal app with Appwrite and RxDB. Check out the step-by-step guide here: appwrite.io/blog/post/offlin…

DB abstraction is useless for 99% of applications like, how many times have you swapped out the DB? how many times have you done it and it’s been smooth, despite the abstraction? oh, you’ve chosen postgres? now you can’t take advantage of it you’re forced to build against the lowest common denominator you’ve hamstrung yourself well done

I've been exploring offline-first paradigm for @youcraftinc and here're a few interesting things I've noticed: - Syncing different entities becomes so similar, you end up writing a generic sync engine (thanks to libraries like @rxdbjs that make this quite easy). - The dev experience feels smoother, almost enjoyable – you build features keeping local database in mind, and syncing feels almost automatic. - It naturally sets you up for nice features like end-to-end encryption or Bring-Your-Own-Cloud.
