React Native Project & Folder Structure

? React Native Project & Folder Structure

? Quick Overview

A well-organized React Native project structure helps developers write clean, scalable, and maintainable mobile applications. Understanding each file and folder allows you to debug faster, collaborate better, and follow industry standards.

? Key Concepts

  • Entry point of the application
  • Platform-specific folders for Android and iOS
  • Reusable components and screens
  • Configuration and dependency files

? Syntax / Theory

When you create a new React Native app using CLI, a default folder structure is generated. Each file has a specific role, from bootstrapping the app to rendering UI components.

? View Code Example
// Typical React Native project structure
myApp/
├── android/
├── ios/
├── node_modules/
├── src/
│   ├── components/
│   ├── screens/
│   ├── navigation/
│   └── assets/
├── App.js
├── index.js
├── package.json
└── app.json

?️ Code Example(s)

? View Code Example
// index.js is the entry point of the app
import {AppRegistry} from 'react-native';
import App from './App';
import {name as appName} from './app.json';

AppRegistry.registerComponent(appName, () => App);

? Live Output / Explanation

What Happens Here?

The index.js file registers the root component using AppRegistry. React Native loads App.js and starts rendering the UI from there.

Click on any folder or file in the "Project Tree" on the left to understand its specific purpose in the React Native ecosystem.

? Use Cases

  • Large-scale mobile applications
  • Team-based development
  • Feature-based folder organization
  • Easy maintenance and scalability

✅ Tips & Best Practices

  • Keep reusable UI inside components
  • Separate screens and navigation logic
  • Group files by feature for large apps
  • Avoid cluttering the root directory

? Try It Yourself

  1. Create a new React Native app
  2. Add a src folder
  3. Move screens and components into it
  4. Update imports accordingly
