Expo SDK 57 will be the easiest upgrade you've ever made. One command. No breaking changes. And boom, you're on React Native 0.86. It's also the first step toward a new release cadence we're considering: optional, non-breaking upgrades between the big SDKs: try.expo.dev/bluesky-sdk57

Trust your instincts. If your app feels slow today, there's probably a cold-start regression on a specific build, on specific devices... this has always been a difficult problem to identify. Now it's not. Our new "Observe" service is in open beta, free up to 10k MAUs. → try.expo.dev/observe-beta...

App.js is one of the biggest events in the React Native & Expo world every year. Can't make it to the conference in person? We're bringing the App.js experience to Kiel! 📺 Live talks 💬 Interesting Discussions 🍻 Drinks sponsored by bitglow Would love to see the local mobile dev community there 👋

The left side features bold text announcing the React Native and Expo community watch-along, including event details, icons, and meetup information. The right side shows a cozy office-style watch party with developers sitting together, watching an App.js conference talk on a large screen. The design uses React blue, yellow highlights, and a modern tech meetup atmosphere.

JSON.stringify() turns your Date into an ISO string. JSON.parse() gives you back a string - not a Date! TypeScript won't warn you. Your app crashes at runtime. 💀 I hit this in a persisted Zustand store recently. Read more: 👇 www.bitglow.de/blog/date-se... #TypeScript #Zustand #ReactNative

I’ve been working with both native Swift and React Native / Expo for years, and my experience is quite different. Especially things like fast refresh and the component model make iteration feel much lighter in RN.

Oliver Kwast @baumstumpf.bsky.social · 18/04/2026

Yeah, in development things can behave a bit differently around the splash screen. Before adding a delay, you could try hiding the splash screen after the first render has completed. If it’s hidden earlier, you might see a blank screen until the first render is done.

010

Oliver Kwast @baumstumpf.bsky.social · 17/04/2026

Does this also happen in production builds? One thing to check: when exactly are you hiding the splash screen? Before or after the first render? In some cases it helps to delay hiding it just a bit longer.

Sounds like the perfect timing for it 😄 Happy to help when that moment comes.

That “we can’t complete the process right now” loop is rough… We’ve seen similar issues during Apple enrollment where things just get stuck without any useful signal. Happy to share what worked for us if you ever revisit it.

IMO it’s actually really good. It’s been my go-to solution since 2018, and it keeps getting better all the time. Are you thinking about developing an app, or just curious?

010

Oliver Kwast @baumstumpf.bsky.social · 06/03/2026

Oh, I’d love to give that a try! Widgets were already possible, but any simplification is always welcome.

Thanks for sharing! Curious if you also looked into the React Compiler for this kind of optimization.

Great! A lot has improved in terms of tooling and onboarding over the last years. Glad to hear it shows 🙂 One of the nice things with React Native is that you rarely need to do a full native build. If you run into any difficulties along the way, feel free to reach out.

Oliver Kwast @baumstumpf.bsky.social · 17/02/2026

Haha, now imagine being a classic native developer. Move a view 2pt --> recompile 🤣 But sounds like a great test app. How’s it been so far?

100

Oliver Kwast @baumstumpf.bsky.social · 17/02/2026

Yeah, same thought here. The ecosystem size definitely matters. Plus React usually follows quite consistent patterns which probably helps as well.

000

Oliver Kwast @baumstumpf.bsky.social · 17/02/2026

Completely agree. It’s probably not just JS, but the huge amount of React code available. And React tends to follow clearer patterns. Other areas are often more individual, which makes suggestions probably less reliable.

Especially the relocating views part looks amazing. I once implemented something similar on the native side for a video player. Having a simpler way to achieve that sounds really promising.
