Just published expo-opfs. If you're building an @expo app and want to use a web library that needs the Origin Private File System (OPFS), this polyfill based on expo-filesystem makes it work out of the box.

The browser is your database: The #ThickClient is making a comeback. Here’s how next-generation local databases like PGlite and RxDB are bringing feature-rich #DataStorage to the browser. https://t.co/EL8lBK8O14

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.

[Paul Snively @JustDeezGuy]

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 <https://t.co/ouRJZj44rV> and <https://t.co/KczfLZnrLP>).

[freeCodeCamp.org @freeCodeCamp]

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.

Imagine teams at a remote construction site logging equipment data, tracking materials, and recording safety checks; all without worrying about losing connectivity.

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!

@dannytt @housecor A RxDB-Tanstack/db plugin is in the making

[Adrian Carolli @icookandcode]

In 2025 sync will be the new way we fetch data.

Thanks for hosting this! @gala_labs, @buildclub_, @AnnieLiao_2000 @tanmay_jain_

Thanks @cursor_ai for shipping the best IDE and being my main inspiration!

Thanks @nextjs, @langchain, @huggingface, @AnthropicAI, @rxdbjs for making this possible to build in a matter of days!

1/5. 🧵 Build Front End Apps That NEVER Go Offline with RxDB 🚀

Struggling with offline capabilities and real-time updates in your apps? Meet RxDB, your reactive, offline-first NoSQL database for modern JS apps.

[Appwrite @appwrite]

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: https://t.co/2Lsk75L5Or

[RxDB | JavaScript Database @rxdbjs]

Meet the brand-new RxDB Appwrite Plugin! This integration allows you to seamlessly replicate local-first data from RxDB's client-side database to @appwrite’s scalable cloud platform for real-time sync and offline functionality.
No more complex setups - start building better apps now: https://t.co/NmgsDwszcC

[Slim Jimmy @slimjimmy]

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

[Aneeq @aneequrrehman]

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.
