React Native 0.76 is here, bringing game-changing features and improvements that boost performance, simplify debugging, and reduce app size. Here’s a quick breakdown of the major updates.
1. New Architecture Now Default
- What Changed: The new JavaScript Interface (JSI) replaces the old bridge, enabling direct communication with native code without data serialization.
- Impact: Faster app performance, as JSI eliminates the bottlenecks of the old bridge.
-
Fallback: You can still switch back to the old architecture if needed by modifying
gradle.properties(Android) or running a command (iOS).
2. New React Native DevTools
- The Problem: Debugging was hard due to overlapping tools (Flipper, Hermes, etc.).
- Solution: The new DevTools combines debugging tools into a single stack with zero setup required, accessible from the Dev menu.
- Bonus: Includes built-in React DevTools with enhanced capabilities like web breakpoints.
3. 15x Faster Metro Build
- Update: Metro Resolver’s new version (v0.80.11) significantly speeds up builds by optimizing module loading.
- Result: Builds are 15 times faster, enabling quicker iteration and feedback during development.
4. New Style Props: boxShadow and filter
- boxShadow: Adds shadows to elements with control over position, color, size, and blur.
- filter: Applies visual effects like brightness and saturation adjustments.
- Benefit: Consistency with web styling, making it easier to create visually appealing apps.
5. Smaller Android App Bundle
-
Improvement: Android apps now bundle C++ libraries into a single
libreactnative.so, reducing the app size by ~3.8MB and startup time by 15ms. - Why It Matters: Smaller APKs improve download and install times, especially beneficial for emerging markets.
6. Expo SDK 52 Update
- What’s New: Expo SDK 52 (beta) supports React Native 0.76, making it easier to leverage these new features within the Expo ecosystem.
In Summary
React Native 0.76 combines years of work into a powerful update, with the new architecture, faster builds, streamlined DevTools, new styling capabilities, and smaller Android apps. This release sets the stage for more efficient and performant React Native applications.
