Advanced tools
React Native is an open-source mobile application framework created by Facebook. It is used to develop applications for Android, iOS, Web, and UWP by enabling developers to use React along with native platform capabilities. It allows for the development of mobile apps using JavaScript and React, offering a rich mobile UI library and tools to deliver a native app experience.
UI Components
React Native provides a set of built-in core components like View, Text, and Image that you can use to build your app's UI. These components are pre-styled and ready to use, making it easy to develop complex UIs.
import { View, Text } from 'react-native';
function HelloWorldApp() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
<Text>Hello, world!</Text>
</View>
);
}
Native Modules
Native Modules allow you to write modules in native code that can be called from JavaScript. This is useful for accessing platform-specific functionality that is not covered by the built-in React Native components.
import { NativeModules } from 'react-native';
const { CalendarModule } = NativeModules;
CalendarModule.createCalendarEvent('testName', 'testLocation');
Navigation
Navigation is essential for mobile apps. React Native can integrate with libraries like React Navigation to provide a way to navigate between screens.
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
const Stack = createStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName='Home'>
<Stack.Screen name='Home' component={HomeScreen} />
<Stack.Screen name='Profile' component={ProfileScreen} />
</Stack.Navigator>
</NavigationContainer>
);
}
Flutter is Google's UI toolkit for crafting beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. It is similar to React Native but uses Dart instead of JavaScript. Flutter provides its own widgets, which are drawn by the framework's own graphics engine.
Ionic is a popular framework for building hybrid mobile applications using web technologies like HTML, CSS, and JavaScript. It differs from React Native as it focuses on web technologies and uses Cordova or Capacitor to access native device features.
NativeScript is an open-source framework for developing truly native mobile applications using JavaScript, TypeScript, Vue.js, or Angular. It provides direct access to native APIs and performance similar to React Native, but it allows for a broader choice of frameworks for building the UI.
React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.
See the official React Native website for an introduction to React Native.

The website’s documentation divided into multiple sections.
View
and Navigator
.Another great way to learn more about the components and APIs included with React Native is to read their source. Look under the Libraries
directory for components like ScrollView
and Navigator
, for example. The UIExplorer example is also here to demonstrate some of the ways to use these components. From the source you can get an accurate understanding of each component’s behavior and API.
The React Native documentation only discusses the components, APIs and topics specific to React Native (React on iOS and Android). For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
git clone https://github.com/facebook/react-native.git
cd react-native && npm install
Now open any example (the .xcodeproj
file in each of the Examples
subdirectories) and hit Run in Xcode.
If you encounter a bug with React Native we would like to hear about it. Search the existing issues and try to make sure your problem doesn’t already exist before opening a new issue. It’s helpful if you include the version of React Native and OS you’re using. Please include a stack trace and reduced repro case when appropriate, too.
The GitHub issues are intended for bug reports and feature requests. For help and questions with using React Native please make use of the resources listed in the Getting Help section. There are limited resources available for handling issues and by keeping the list of open issues lean we can respond in a timely manner.
