Expo for React Native

Expo is the leading open-source platform for building universal React Native apps that run on Android, iOS, and the web from a single JavaScript codebase. It provides a managed workflow with pre-built native modules, a cloud build service (EAS Build), and over-the-air updates — so you can ship your app without owning a Mac or knowing Xcode.

With Expo SDK, you get access to camera, notifications, location, biometrics, and 50+ other native APIs through a consistent, well-documented JavaScript interface — dramatically reducing the native development knowledge your team needs.

How Expo will help you grow and be more successful?

1. Start building in minutes, not days. npx create-expo-app scaffolds a fully configured React Native project with TypeScript, navigation, and native modules ready to go — no Xcode or Android Studio configuration required to see your app on a real device.
2. Ship updates instantly without the App Store review cycle. Expo's Over-the-Air (OTA) update system lets you push JavaScript and asset changes directly to your users' installed apps — critical bug fixes reach production in minutes, not days.
3. Build for iOS from any operating system. EAS Build runs your iOS and Android builds in the cloud, so your Linux or Windows developers can produce App Store-ready builds without owning Apple hardware — removing the biggest infrastructure bottleneck in React Native teams.
