Once you're up and running with Create React Native App, visit[the tutorial on reactnative.dev](https://reactnative.dev/docs/tutorial) and[the tutorial on expo.dev](https://docs.expo.dev/tutorial/introduction/) for more information on building mobile apps with React.

<b>It's recommended to use a framework to build apps with React Native, <ahref="https://reactnative.dev/docs/environment-setup">learn more</a>.</b>

</p>

-`npx create-react-native-app` Create a new native React app.

-`npx crna` Alias for`npx create-react-native-app`.

-`npm run ios` -- (`npx expo run:ios`) Build the iOS App (requires a MacOS computer).

-`npm run android` -- (`npx expo run:android`) Build the Android App.

-`npm run web` -- (`npx expo start --web`) Run the website in your browser.

By default you create a[bare workflow React](https://docs.expo.dev/bare/overview/) project with support for iOS, Android, and web. The project comes preconfigured with support for[Expo Modules](https://docs.expo.dev/modules/overview/), an API writing native modules using Swift and Kotlin, and this also makes it possible to use any library in the[Expo SDK](https://docs.expo.dev/versions/latest/).

You can opt to use an example project instead by selecting the "Templates from ..." option. Custom templates can be used with`--template <Example Name or GitHub URL>` option.

- Use an[example](https://github.com/expo/examples):`npx create-react-native-app -t with-typescript`

- Use a custom template:`npx create-react-native-app --template https://github.com/someone/my-react-starter` -- Only works with GitHub repos on the master branch.

- All examples can be modified in the[expo/examples](https://github.com/expo/examples) repo.

Expo Go enables you to work with all of the[Components and APIs](https://facebook.github.io/react-native/docs/getting-started) in`react-native`, as well as the[JavaScript APIs](https://docs.expo.io/versions/latest) that the are bundled with the Expo app.

<br />

- Download the "Expo Go" app from the Play Store or App Store.

- Start your project with Expo CLI:`npm start`

- Open the project by scanning the QR code in the terminal.

If you're having issues with Create React Native App, please make sure:

- The issue is not covered in the[Expo Docs](https://docs.expo.io/versions/latest/)

- There is not already an[open issue](https://github.com/expo/create-react-native-app/issues/) for your particular problem

If you've checked the documentation and currently open issues, please either[open a new GitHub issue](https://github.com/expo/create-react-native-app/issues/new) or ask a question on[Expo Community Discord](https://chat.expo.dev).

Refer to the[Contributing guide](https://github.com/expo/create-react-native-app/blob/main/CONTRIBUTING.md) for more information.

The examples feature was inspired by the`templates` system of[create-next-app](https://github.com/zeit/next.js/tree/canary/packages/create-next-app) by the[Vercel](https://vercel.com/) team.

CRNA is focused on being the fastest way to bootstrap a React Native app without worrying about the native platforms or bundlers required for developing and shipping apps. Other tools provide both an init script (which is slower) and a suite of other tools that can be used for interacting with the project. CRNA is meant to be used with any of the following tools:

-[Expo CLI](https://docs.expo.dev/more/expo-cli/) by[Expo team](https://expo.dev)

-[Ignite CLI](https://github.com/infinitered/ignite) by[Infinite Red](https://infinite.red/)

-[React Native Community CLI](https://github.com/react-native-community/cli) by members of[the React Native community](https://github.com/orgs/react-native-community/people)

$ npx create-expo --help
