Turbo Modules improve React Native app speed by making native modules load faster and communicate more efficiently. This helps keep animations smooth at 60 frames per second, reducing UI jank. They also lower memory use by loading modules only when needed, which saves battery life on mobile devices.
Use Turbo Modules to avoid blocking the JavaScript thread. Write native code that is lightweight and asynchronous. Avoid heavy work on the main thread. Use lazy loading so modules load only when required. This keeps the UI responsive and animations fluid.
Turbo Modules can reduce startup time by loading native modules on demand instead of all at once. This means your app launches faster. The overall app size may slightly increase due to the Turbo Module infrastructure, but the impact is small compared to the performance benefits.
On iOS, Turbo Modules use Objective-C++ and the new C++ bridge for faster calls. On Android, they use Java and JNI with optimized threading. Both platforms support Turbo Modules but require different setup steps. iOS apps need to enable Turbo Modules in the Podfile, while Android apps configure them in Gradle and Java code.
If your app takes 5 seconds to load a screen using Turbo Modules, likely causes include blocking the JavaScript thread with heavy synchronous native calls or loading too many modules at startup. Check for synchronous native code and switch to asynchronous calls. Use lazy loading to defer module initialization until needed.
