React Native Native Modules with Example: Traditional Way vs TurboModules (2025 Guide)

React Native Native Modules with Example: Traditional vs TurboModules (2025) React Native provides powerful capabilities to communicate with platform-specific code using Native Modules . With the new TurboModules architecture, this process becomes more efficient, performant, and memory-friendly. In this blog, we’ll explore both the traditional and TurboModules approaches, compare them, and provide code examples. 📚 What is a Native Module in React Native? Native Modules allow you to write platform-specific functionality in Java (Android) or Objective-C/Swift (iOS) and expose it to your React Native JavaScript code. ⚙️ Traditional Native Modules (Old Architecture) In the traditional model, native modules are registered using ReactPackage and invoked via the bridge (async communication). 🧪 Android Example (Java) // MyModule.java public class MyModule extends ReactContextBaseJavaModule { public MyModule(ReactApplicationContext context) { sup...

🧠 How React Native Internally Works (2025 Edition)

How React Native Internally Works (2025 Edition) React Native is a powerful framework for building cross-platform mobile applications using JavaScript. But how does it bridge the gap between JavaScript and native mobile platforms? Let’s dive into the internals of React Native and understand its architecture. 🏗️ 1. Core Architecture Overview React Native’s architecture has evolved significantly: Era Key Feature Legacy Architecture Bridge model with async JSON message passing Fabric (2022+) Synchronous layout + native rendering New Architecture (2023+) TurboModules + JSI + Codegen + Fabric 🔗 2. JavaScript & Native Bridge (Legacy) In the legacy model, JavaScript and native code communicated via a...

Best React Native Animation Libraries & UI Components in 2025

Best React Native Animation Libraries & UI Components of 2025 With modern UX expectations on the rise and React Native evolving rapidly (especially with the New Architecture), choosing the right animation and UI libraries is crucial in 2025. Here’s a curated list of the best, production-ready tools — each with a brief explanation and example to get you started fast. 🥇 1. React Native Reanimated 3 Why it’s best: Native-threaded animations, FLIP support, seamless with Gesture Handler, New Architecture-ready. Use case: Shared element transitions, swipe gestures, layout interpolation. import Animated, { useSharedValue, useAnimatedStyle, withSpring, } from 'react-native-reanimated'; const AnimatedBox = () => { const offset = useSharedValue(0); const animatedStyle = useAnimatedStyle(() => ({ transform: [{ translateX: withSpring(offset.value * 100) }], })); return ( <TouchableWithoutFeedback onPress={...

⚠️ React Native 0.79 (New Architecture) – Common Issues & Quick Fixes

React Native 0.79 (New Architecture) – Common Issues & Fixes With React Native 0.79 (part of Expo SDK 53 ), the New Architecture — which includes TurboModules , Fabric , and JSI — is now enabled by default. While this delivers better performance and platform-native alignment, many developers are encountering critical issues while upgrading or starting fresh projects. 🔍 Brief: What’s Going Wrong? 1. Third-Party Library Crashes Libraries like react-native-maps or @stripe/stripe-react-native might crash due to incompatibility with TurboModules or Fabric rendering. 2. Build & Runtime Errors Common issues include build failures related to CMake, Hermes, or JSI, and runtime UI bugs — especially on Android with edge-to-edge layout behavior. 3. Component Rendering Issues Blank screens, flickering components, or gesture conflicts due to changes in how the new rendering system manages views. ✅ Solutions & Fixes 1...
