Introducing our Capacitor JS SDK (Alpha) 🎉

It extends the PowerSync Web SDK so you can use the same APIs in Capacitor apps (iOS, Android, web), while adding native SQLite support for stronger persistence and performance on mobile platforms.

With our Vite + React + TS template, you can set up a fully self-hosted development environment using @supabase.com with just a few commands.

Expo's BackgroundTask API can be used to keep in-app SQLite synced even when apps are minimized.

Background tasks aren't perfect: they can be aggressively throttled by the OS to preserve battery and resources etc.

But when the stars align it feels like magic.

With @expo.dev background tasks, keep apps in sync even when they're minimized.

Demo flow:
1. Minimize app
2. Add 5,000 new records on @supabase.com
3. Open app → new records already downloaded

Using @expo.dev with real-time synced SQLite means that instead of having to:

• manage network requests
• handle loading states
• implement retry logic
• orchestrate state management between your local cache and remote data

You just write queries™

The quickest way to spin up a PowerSync app is by using a fully self-hosted setup with @supabase.com and our @vite.dev template app.

We're trying something new for our June newsletter 👀

Inspired by Fly[dot]io, we're sharing more about the engineering reasoning behind our latest product updates.
