React Native Expo (2025 Edition)

Expo in React Native: Everything You Need to Know (2025 Edition)

Everything You Need to Know About Expo in 2025 🚀


Expo is a framework and platform for universal React applications. It simplifies the development and deployment process of React Native apps with powerful tools and services. As of 2025, Expo has matured into an all-in-one toolkit that supports everything from development to distribution.

📦 What is Expo?

Expo is a set of tools built around React Native to help you build native iOS, Android, and web apps using JavaScript and React. It removes native dependencies, making it easier for JavaScript developers to build and deploy native apps quickly.

🧰 Key Services Provided by Expo

  • Expo Go: Preview your app without needing to build a native binary.
  • Expo Dev Client: Customizable development client for testing native modules.
  • EAS Build: Build your app in the cloud for iOS and Android.
  • EAS Submit: Submit builds to the App Store and Google Play from the CLI.
  • EAS Update: Push over-the-air (OTA) updates instantly to your users.
  • EAS Metadata: Manage app store metadata programmatically.
  • Expo Application Services (EAS CI/CD): Full continuous integration and deployment pipeline integrated with your Git provider.

🔄 EAS Update (Over-the-Air Updates)

With EAS Update, you can push code and asset changes directly to users’ devices without waiting for App Store or Play Store approval.

eas update --branch production

Changes are downloaded automatically the next time the user opens the app (or immediately, depending on your update strategy).

⚙️ Expo Dev Client

Create a custom version of Expo Go that includes your own native modules. This lets you test features without needing to build full release builds every time.

📲 EAS Build

EAS Build allows you to compile native binaries in the cloud for iOS and Android. No Xcode or Android Studio required locally.

eas build --platform all

📡 EAS Submit

Once you have your build, submitting it to app stores is a single CLI command:

eas submit --platform ios

🔁 EAS CI/CD Support

Expo now offers full support for continuous integration and delivery. You can connect your GitHub, GitLab, or Bitbucket repositories to run builds on every push, run tests, and deploy automatically.

🆕 Expo SDK Updates (2025)

The latest Expo SDK (v53+) brings in support for:

  • React Native 0.79+
  • React 19
  • Edge-to-edge support for Android
  • Stable expo-audio and expo-maps
  • Improved Jetpack Compose & SwiftUI interop
  • Hermes as default JS engine

🌐 Web Support

Expo also provides first-class support for building web applications using expo-router and React Native for Web. With one codebase, you can run apps on Android, iOS, and web.

📍 Who Should Use Expo?

  • Teams that want rapid prototyping and OTA updates
  • Startups with fewer native needs and faster delivery expectations
  • Developers who want to focus more on JavaScript than native configuration

🧠 Final Thoughts

Expo is not just a beginner's toolkit anymore — it’s a mature platform used by companies at scale. With EAS services, custom Dev Clients, and full CI/CD support, it's an end-to-end solution for mobile app development in 2025.

⚠️ 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 🚀 ...
