Expo SDK 53 Beta Now Live – Explore New Features Today

New Release: Expo SDK 53 Beta Now Available for Developers


Here are the key highlights from the Expo SDK 53 release notes that are particularly relevant for your interest in performance improvements, new features, and support for various modules:



🚀 Performance & Architecture

1. New Architecture is Now Default

  • All new projects (npx create-expo-app) will now use the New Architecture by default.

  • This includes Hermes, Fabric, and TurboModules for both iOS and Android.

  • You can still disable the new architecture by setting EXPO_ENABLE_NEW_ARCHITECTURE=false.

2. Startup Time Improvements

  • Thanks to the New Architecture and general optimizations, startup performance has improved.

  • Support for React Native 0.73, bringing improved performance, bug fixes, and updated UI features.



🧩 Module & Feature Updates

3. expo-router 3.7 (Edge-to-Edge UI)

  • Automatically enables full-screen edge-to-edge layouts by default (like immersive UIs).

  • Offers better integration with system gestures, navigation bars, and safe areas.

  • No need to manually manage react-native-safe-area-context as much anymore.

4. expo-maps (Replaces react-native-maps)

  • First-class support in SDK 51.

  • Uses Google Maps on Android and MapKit on iOS.

  • Improved performance and compatibility with New Architecture.

5. expo-av and expo-audio

  • Both packages are now better optimized and are New Architecture compatible.

  • You can build performant audio and video apps with full support across platforms.



🔧 Other Developer Experience Updates

6. Background Tasks

  • expo-task-manager and related APIs like expo-location background features now fully support New Architecture.

  • More reliable execution in background modes, especially with new iOS/Android system restrictions.

7. Expo CLI Improvements

  • Faster startup, more stable error handling, and better logging.

  • New commands to toggle between architectures and development builds easily.



🔜 What’s Coming Next

  • Improvements for Web and Server Components integration.

  • Further migration of older modules to Fabric-compatible versions.

  • Better EAS integration with monorepos and TurboModules.

⚠️ 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...

Edge-to-Edge UI in Android with React Native: How to Do It Right (2025 Update)

Intro Starting from 2024-25, Android apps are expected to embrace edge-to-edge UI — where your app content flows behind the system bars (status bar, navigation bar) for a fully immersive experience. Google is pushing for it hard, and React Native (especially with New Architecture and Expo SDK 53+) has made it much easier to implement. In this blog, I’ll walk you through: ✅ Why edge-to-edge matters for modern Android apps ✅ How to implement it correctly in React Native (Expo & Bare projects) ✅ Handling tricky parts like keyboard, gestures, and safe areas ✅ Real-world gotchas I ran into — and how to fix them Why Edge-to-Edge? Modern Android design guidelines (Material You) heavily prefer edge-to-edge layouts. It makes apps feel more native, more immersive, and makes better use of larger phone screens. Plus, starting Android 15, apps that don't adopt it might feel noticeably "outdated". How to Do It in React Native 🚀 ...

React Native Expo (2025 Edition)

Expo in React Native (2025 Edition): Real-World Experience Expo in React Native (2025 Edition): Real-World Experience, Pros, Cons & Use Cases 🚀 I’ve been working with React Native for several years and have shipped multiple production applications using both bare React Native and :contentReference[oaicite:0]{index=0} . In 2025, Expo is often misunderstood — some developers still think it’s only for beginners, while others treat it as a magic solution for everything. This article is not a documentation rewrite. Instead, I’m sharing how Expo actually behaves in real projects, where it shines, where it struggles, and when it makes sense to use it. What Is Expo (In Simple Terms)? Expo is a framework and ecosystem built on top of React Native that helps you build iOS, Android, and web apps faster by reducing native setup and handling builds, updates, and deployments for you. In 2025, Expo has evolved into a production-ready platform used by st...
