React Native

React Native lets you build native apps using React. Written in JavaScript, rendered with native code.

Native UI. React Native primitives render to native platform UI, meaning your app uses the same native platform APIs other apps do. Gestures, text scaling, and accessibility behave the way users expect on each OS.
React, everywhere. Declarative UI, components, hooks, and Suspense, reused across Android, iOS, and other platforms.
Developer Velocity. See local changes in seconds. Changes to JavaScript code are applied with Fast Refresh, without rebuilding the native app.
Extend it yourself. Native Modules let you call platform code directly from JavaScript, synchronously and type-safe — or reach for thousands of existing libraries.

React Native is developed and supported by many companies and individual core contributors. Find out more on the React Foundation website.

Building your first React Native app

Follow the Getting Started guide for a new app, or Integration with Existing Apps to adopt React Native incrementally.

Using a Framework

We believe that the best way to experience React Native is through a Framework, a toolbox with all the necessary APIs to let you build production ready apps. Expo is a production-grade React Native Framework, with file-based routing, a standard library of native modules, and much more.

To create a new Expo project, run the following in your terminal:

npx create-expo-app@latest

Then follow the rest of Expo's getting started guide to start building.

Without a Framework

You can also use React Native without a Framework, however we've found that most developers benefit from one — navigation, native dependencies, and platform tooling are problems the ecosystem has already solved. If a Framework doesn't suit your app, follow Getting Started Without a Framework.

Documentation

The full documentation for React Native can be found on our website.

The source for the React Native docs and website is hosted on a separate repository, react/react-native-website.
