#ReactNative Pro Tip #14: Disable compression for .𝚋𝚞𝚗𝚍𝚕𝚎 files in your Android app to speed up it's launch time - in our tests this resulted in a 400ms (!) startup time improvement! 🚀 Simply add this to your 𝚊𝚙𝚙/𝚋𝚞𝚒𝚕𝚍.𝚐𝚛𝚊𝚍𝚕𝚎:

We built something cool! 🤩 This is running smoothly at 60FPS+ in a #ReactNative app, the custom models were created in Blender, and the face tracking, filtering and rendering is written from scratch in a native Swift module. 💪 Stay tuned for what's coming to VisionCamera... 👀

#ReactNative Pro Tip #8: Never use the <Text> component directly. Instead, create your own abstraction so you don't repeat yourself with font name, font size or colors each time and it's easier to change properties at any point.

We just open-sourced our high-performance Graph library for React Native! 🥳🎉 It uses React Native Skia for fast rendering and native path interpolation for 60 FPS animations! 🤯 @PinkPandaDefi's mobile app already uses react-native-graph! Leave a ⭐️: github.com/margelo/react-…

#ReactNative Pro Tip #6: When presenting numbers to the user, you should format them in the correct locale (commas, currency signs, ..) While .toLocaleString(..) does it's job, you can actually construct your own NumberFormat instance to improve performance by ~2x! 💨

#ReactNative Pro Tip #5: Use react-native-blurhash to show beautiful blurry placeholders for your images and videos. Generate a short string that represents a blurry version of your content ("blurhash") server-side and send it alongside with your data to the app!

We're getting closer and closer to an alpha release! 🚀 Our upcoming high performance React Native list solution "WishList" is able to recycle cells with views, text, images, and even state in realtime! This is pretty much as fast as a fully native list - no more blanks! 🥳🤩

#ReactNative Pro Tip #7: Always handle Safe Area Insets appropriately. Instead of wrapping the entire screen in a <SafeAreaView>, you can work with paddings to create cleaner UIs. Here, we passed `contentContainerStyle={{ paddingBottom: safeAreaBottom }}` to the <ScrollView>:

#ReactNative Pro Tip #2: Always use the native-stack from @reactnavigation. Since it uses platform-native screen primitives, it is almost always worth the performance gains over the JS-based stack.
