Build mobile apps with React.
React Native brings [React's][r] declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Portability. Reuse code across iOS, Android, and [other platforms][p].
React Native is developed and supported by many companies and individual core contributors. Find out more in our [ecosystem overview][e].
React Native apps may target iOS 12.4 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo
can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide
. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
- [Trying out React Native][hello-world]
- [Creating a New Application][new-app]
- [Adding React Native to an Existing Application][existing]
The full documentation for React Native can be found on our [website][docs].
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the [React documentation][r-docs].
The source for the React Native documentation and website is hosted on a separate repo, [@facebook/react-native-website][repo-website].
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the [Upgrading Guide][u] for instructions.
