Demo app repo -> github.com/Solarin-Johnso… React Native Ease Repo -> github.com/AppAndFlow/rea…
Our library, react-native-transformer-text-input, can be used for all kinds of formatting. It includes providers for common use cases such as phone numbers, patterns, and currencies. It allows for smooth, fast, and flicker-free text transformations in your @expo apps.
@aljazkosirnik @expo Let us know what you think!
The best apps don't make compromises. Flickers and lag, even if very minimal, do not belong in award-winning applications, which is why we built it. Repo here: github.com/AppAndFlow/rea…
Whenever the team gets together (in person), rare as it is, it calls for some new T-shirts 🥰
I've been using AI agents to iterate on a fix for an iOS React Native TextInput rendering bug overnight, using @CallStack agent-device + RN Tester (the RN repo's example app) as its test loop. The video below replays each fix attempt. 📷
Messing around with react-native-ease from @appandflow after reading @janicduplessis’s excellent article. Really impressive work from the team, the API feels clean super familiar. Can’t wait to push it further and build more things with it. #Reanimated #ReactNative #Animation #Expo #BuildInPublic @appandflow @janicduplessis @expo @charlesvinette
The @appandflow team's react-native-ease library has some cleverly engineered tricks for 0 JS animations 🔥 For starters, a bitmask tells the native side "this prop was actually animated". It looks something like this: bit 0 = opacity bit 1 = translateX bit 2 = translateY bit 3 = scaleX When it comes to reading animations, it actually reads from the presentation layer, so animations never snap. Quite clever. Lastly, I found some cray cray math on the Android side and it turns out that's a harmonic oscillator that makes iOS + Android springs look identical 🤯
We partnered with @expo again for another blog post, this time about animations, performance and frame budget.
When does your React Native animation library actually matter? @janicduplessis from @appandflow benchmarked per-frame UI thread cost across four approaches. Short answer: long-running animations, big lists, low-end devices. One-shot transitions, less so. The full report with
@peterpme Thank you! Would love your feedback once you try it
Flickers don't belong in premium apps! That's why we built react-native-transformer-text-input. Instead of going Native/JS/Native, it runs on the UI thread, thanks to @swmansion 's RN worklets. Demo built in 15 minutes with @expo Skills.
🙌 Expo is the best it's ever been, and it's about to get a lot better. We raised a Series B so we can go faster on the things that matter to you: faster builds, smoother native integrations, and the services to make end-to-end app development a delightful experience. There is a lot of work to do. This round led by @Georgian_io puts us in position to go do it!
Apps are getting better, users' expectations are higher. Platform native components and navigation are a great way to make your app feel premium. With the help of @expo UI and Router, it is easier than ever to make your React Native app feel at home on iOS and Android.
