React builds user interfaces for the web and renders them to the browser's DOM. React Native uses the same React model, components, JSX and Hooks, to render real native views on iOS and Android.

If you know React, you already know most of React Native. What changes is everything around the components: styling, navigation, device access, tooling and how you ship. This article covers the differences between React and React Native, what carries over, what's different on mobile, what changed in React Native over the last two years, and how to run one content setup for both.

#React vs React Native at a glance

#React vs. React Native

In 2013, React emerged from Meta (formerly Facebook)’s need to build dynamic, high-performing web interfaces. React introduced building UIs through a component-based architecture. It also introduced a virtual DOM system that optimized rendering, making applications faster and more responsive.

With React's success in web development, Meta saw an opportunity to extend it to mobile app development. React Native was introduced in 2015 and leveraged the power of React, enabling developers to use a similar component-based UI approach for mobile platforms.

The goal was to allow for a single codebase that could run on iOS and Android, significantly reducing development time and costs compared to traditional native development for each platform.

At their core, React and React Native share the same design philosophy and many functionalities. However, their application domains and technical implementations differ significantly.

React is used to develop web applications that run in a browser environment and leverage HTML and CSS. React Native is used for mobile applications, translating React code into native mobile components by leveraging the native platform's APIs.

For example, the View component simplifies the creation of user interfaces in React Native, rather than writing separate code for each platform in Kotlin/Java for Android or Swift/Objective-C for iOS. At runtime, React Native renders this component as its native equivalent, like UIView on iOS or android.view.View on Android.

#What changed for React Native

React Native looks quite different from the version many comparisons still describe. Here's what moved.

The New Architecture is the only architecture

React Native 0.76 (October 2024) turned on the New Architecture by default. It replaces the old asynchronous bridge with direct, synchronous communication between JavaScript and native code, and it supports concurrent React features. Since 0.84 (February 2026), the release also removes Legacy Architecture components, so new apps and libraries target the New Architecture only.

Hermes V1 by default

React Native 0.84 made Hermes V1 the default JavaScript engine, with better performance for every app, and started shipping precompiled iOS binaries by default for faster builds.

React 19 on both sides

React Native 0.88 (October 2026) ships React 19.3, the same React version you'd use on the web. Actions, the use API and ref as a prop work the same way in both.

Start with a framework

The React Native docs recommend building new apps with a framework, and Expo is the one they point to. Expo adds file-based routing with Expo Router, a standard library of native modules and cloud builds. Expo SDK 54 and later also enable React Compiler by default, so most manual memoization disappears from new mobile code.

#Things that carry over well from React to React Native

For developers familiar with core React concepts, architectural principles, and performance optimization techniques, learning React Native should be smooth. Let’s explore some aspects that carry over well.

Core React concepts

React's core concepts, such as the component lifecycle, composition, and the use of JSX, are consistent in React Native, making the knowledge transfer straightforward.

1. Component lifecycle

The lifecycle methods or hooks in React help manage the lifecycle of components, such as mounting, updating, and unmounting. These are also the same in React Native.

import React, { useEffect } from 'react';
    import { View, Text } from 'react-native';
    
    function App() {
      useEffect(() => {
        // ComponentDidMount
        console.log('Component mounted');
    
        return () => {
          // ComponentWillUnmount
          console.log('Component will unmount');
        };
      }, []);
    
      return <View><Text>Hello, world!</Text></View>;
    }

2. State management

State management in React and React Native works in the same way. You can use hooks like useState to manage local state within components.

import React, { useState } from 'react';
    import { View, Text, Button } from 'react-native';
    
    function Counter() {
      const [count, setCount] = useState(0);
    
      return (
        <View>
          <Text>You clicked {count} times</Text>
          <Button onPress={() => setCount(count + 1)} title="Click me" />
        </View>
      );
    }

3. JSX

JSX is a syntax extension for JavaScript that allows you to write HTML-like code in your JavaScript files. In both React and React Native, JSX describes the UI.

// Mobile application
    import { Text } from 'react-native';
    
    function App() {
      return <Text>Hello, world!</Text>;
    }

React architectural concepts

The architecture of a React application, including state management, data flow, and component structure, can be mirrored in React Native.

1. State management (Redux/Context API)

Whether using Redux for global state management or the Context API for more localized state sharing, the implementation remains the same across React and React Native.

For example, React and React Native can utilize the Context API in the same way to pass data through the component tree without having to pass props down manually at every level.

import React, { createContext, useContext, useState } from 'react';
    
    const CountContext = createContext();
    
    function CountProvider({ children }) {
      const [count, setCount] = useState(0);
      return (
        <CountContext.Provider value={{ count, setCount }}>
          {children}
        </CountContext.Provider>
      );
    }
    
    function useCount() {
      const context = useContext(CountContext);
      if (!context) {
        throw new Error('useCount must be used within a CountProvider');
      }
      return context;
    }

2. HTTP requests (Axios/Fetch API)

The way you make HTTP requests in React with Axios or Fetch API is the same in React Native.

useEffect(() => {
      fetch('https://api.example.com/data')
        .then(response => response.json())
        .then(data => console.log(data));
    }, []);

Performance optimization techniques

Many performance optimization techniques in React, such as memoization, lazy loading, and efficient state management, are also applicable in React Native.

1. Memoization (React.memo/React.useMemo)

These techniques prevent unnecessary re-renders by memoizing the component or values, thus improving performance. With React Compiler, which Expo enables by default, most of this happens automatically, so you'll write React.memo by hand far less often on both platforms.

const MyComponent = React.memo(function MyComponent(props) {
      /* render using props */
    });

2. Lazy loading (React.lazy)

This feature allows you to render a dynamic import as a regular component, reducing the bundle size and speeding up the initial load time.

const OtherComponent = React.lazy(() => import('./OtherComponent'));
    
    function MyComponent() {
      return (
        <React.Suspense fallback={<div>Loading...</div>}>
          <OtherComponent />
        </React.Suspense>
      );
    }

Other React tools

Many tools used in the development ecosystem provide SDKs compatible with React and React Native. This compatibility ensures developers can use the same tooling to monitor performance, track errors, and analyze user behavior across web and mobile platforms.

Tools like Sentry, New Relic, and LogRocket offer SDKs for React and React Native, allowing developers to monitor application performance and track issues in real time.

import * as Sentry from '@sentry/react-native';
    import { View, Text } from 'react-native';
    
    Sentry.init({
      dsn: 'YOUR_SENTRY_DSN'
    });
    
    function App() {
      throw new Error('Test Sentry Error');
      return <View><Text>Hello, world!</Text></View>;
    }

Tools like Bugsnag and Crashlytics can also be integrated into React and React Native to report errors, provide insights into application stability, and help improve user experience.

Google Analytics, Mixpanel, and Amplitude are examples of analytics tools that offer SDKs for both web and mobile platforms. These SDKs enable developers to gather insights into user interactions and app performance.

#Things that are different when developing for mobile with React Native

While the foundational React concepts remain consistent for React Native, the application in mobile environments necessitates adjustments in areas such as styling, library selection, device feature access, and more. Let’s explore some key differences:

1. Styling

CSS is extensively used in React to style components. React Native, however, uses a JavaScript-based styling system influenced by CSS but has its own properties and constraints.

In React, you can use CSS files or inline styles:

function WebComponent() {
        return (
            <div style={{ color: 'blue', margin: '10px' }}>
                Hello, this is a styled web component!
            </div>
        );
    }

In React Native, styles are not defined in CSS files but in JavaScript objects using the StyleSheet.create() method. This approach provides validation and optimization for the styles within the React Native environment.

import { View, Text, StyleSheet } from 'react-native';
    
    function NativeComponent() {
        return (
            <View style={styles.container}>
                <Text style={styles.text}>
                    Hello, this is a styled native component!
                </Text>
            </View>
        );
    }
    
    const styles = StyleSheet.create({
        container: {
            margin: 10,
        },
        text: {
            color: 'blue',
        },
    });

2. Library availability

The ecosystem of libraries in React and React Native can differ significantly due to the distinct nature of web and mobile platforms.

For instance, while axios or fetch can be used for HTTP requests in React and React Native, certain UI component libraries like Material-UI are designed specifically for web use. They cannot be used directly in React Native. Instead, React Native has its own set of UI libraries, such as React Native Paper, that are tailored for mobile development.

3. Mobile hardware vs. browsers

React Native provides direct access to mobile device features like the camera, GPS, accelerometer, etc., which are not as readily accessible or consistent across browsers in web development.

import { Camera } from 'expo-camera';
    
    async function accessCamera() {
        const { status } = await Camera.requestCameraPermissionsAsync();
        if (status === 'granted') {
            console.log('Camera access granted');
        } else {
            console.log('Camera access denied');
        }
    }

In web development, accessing device hardware like the camera is usually more complex and requires dealing with varied browser permissions and APIs.

4. Navigation

Navigation in web apps typically relies on the browser's URL and history, managed by libraries like React Router. In contrast, mobile apps often use stack, tab, or drawer navigation, managed by libraries like React Navigation in React Native. If you start with Expo, Expo Router builds on React Navigation and gives you file-based routes, much like a web framework.

import { NavigationContainer } from '@react-navigation/native';
    import { createStackNavigator } from '@react-navigation/stack';
    
    const Stack = createStackNavigator();
    
    function NativeApp() {
        return (
            <NavigationContainer>
                <Stack.Navigator>
                    <Stack.Screen name="Home" component={HomeComponent} />
                </Stack.Navigator>
            </NavigationContainer>
        );
    }

5. Releases

The process of releasing applications is markedly different between web and mobile environments.

The release process for React web apps is straightforward: build the project and deploy the output to a server. This process can be automated with CI/CD pipelines.

In React Native, mobile apps are distributed through app stores (Apple App Store, Google Play Store), requiring compliance with platform-specific guidelines and a review process before release.

Updates to mobile apps must be pushed through these stores and are subject to approval, which can delay availability. Over-the-air update services such as EAS Update can ship JavaScript-only fixes without a full store release.

6. Development and dev experience

Developing in React and React Native offers distinct experiences, particularly due to the underlying platforms and tooling differences.

Developers can use hot module replacement (HMR) with tools like Vite, enabling real-time updates in the browser during development.

Debugging is often done directly in the browser using built-in developer tools.

React Native uses the Metro bundler and Fast Refresh, so developers see the results of their latest changes immediately on a simulator or device.

Debugging has improved since React Native DevTools arrived in 0.76, but some issues still require platform-specific tools like Xcode for iOS or Android Studio for Android.

7. Testing

Testing strategies can vary significantly between web and mobile due to platform-specific elements.

Common testing frameworks include Jest or Vitest for unit tests and React Testing Library for component tests. End-to-end testing can be done with tools like Cypress, Playwright or Selenium.

import { render, screen } from '@testing-library/react';
    import App from './App';
    
    test('renders hello world', () => {
      render(<App />);
      expect(screen.getByText('Hello, World!')).toBeInTheDocument();
    });

Jest can also be used for unit testing in React Native, together with React Native Testing Library for components. Detox or Appium are popular choices for UI and integration testing, providing a way to automate user interactions on real devices.

import { render, screen } from '@testing-library/react-native';
    import App from './App';
    
    test('renders hello world', () => {
      render(<App />);
      expect(screen.getByText('Hello, world!')).toBeOnTheScreen();
    });

8. CI/CD

Continuous Integration and Continuous Deployment (CI/CD) practices are crucial in both environments but have different focuses and tools.

CI/CD for the web involves automated testing, build, and deployment processes using tools like Jenkins, GitHub Actions, or GitLab CI. The web app's assets are compiled, tested, and then deployed to a web server or a CDN.

For React Native, CI/CD includes additional steps like building app binaries, running mobile-specific tests, and submitting the app to the relevant app stores using tools like Fastlane or EAS Build and Submit.

Mobile CI/CD must handle multiple environments (iOS, Android) and may include beta distribution through TestFlight or Google Play Beta.

9. Performance Optimization

Optimizing performance requires different approaches and considerations for web and mobile.

For React, focus on reducing bundle size, optimizing assets, and improving network performance. Bundlers like Vite can split code and lazily load parts of the application.

For mobile, performance optimization often revolves around reducing memory usage, optimizing native code interactions, and ensuring smooth animations. To diagnose and optimize performance, profiling tools specific to iOS or Android, as well as React Native DevTools, are used.

#Where does the content in your React and React Native apps come from?

Sharing Hooks and data fetching between web and mobile is the easy part. Sharing content is where most teams end up copying text into two places. If articles, product details and in-app messages live in one structured model, both apps query the same entries and each one decides how to present them, which is the idea behind an omnichannel headless CMS. With a typed schema, your coding agent can also build the web screen and the native screen from the same fields. Hygraph, the agentic content platform and headless CMS, serves that content through one GraphQL API, and its MCP server lets Claude Code, Cursor or VS Code read the schema and create or update entries, while deleting and unpublishing stay blocked. Next, see how to use Hygraph as the CMS for your React Native app.

#Conclusion

While React and React Native share many principles and techniques, the specifics of mobile development bring unique challenges and considerations.

By understanding these differences and leveraging the shared strengths, developers can efficiently build robust, cross-platform applications that deliver exceptional user experiences.
