React Native Tutorials Roadmap

Section 1: Introduction to React Native and Mobile Development Basics

• What is React Native?
  • A JavaScript framework for building native mobile apps.
  • Allows you to write code once and deploy to both iOS and Android.
  • Uses native components, resulting in a native look and feel and performance.
  • Based on the React library.
• Why Learn React Native?
  • Cross-platform development saves time and resources.
  • Large and active community.
  • Leverages existing React knowledge.
  • Good performance for many types of applications.
  • Access to native device features.
• Mobile Development Fundamentals (Basic Concepts):
  • Understanding mobile app architecture (basic).
  • Difference between native, hybrid, and web apps.
  • Basic understanding of iOS and Android development ecosystems (optional but helpful).
• Setting up Your Development Environment:
  • Installing Node.js and npm/yarn.
  • Installing React Native CLI or using Expo CLI.
  • Setting up Android Studio (for Android emulator) and Xcode (for iOS simulator - macOS only).
  • Setting up a physical device for testing.
  • Using a code editor (VS Code, Sublime Text, Atom).
• Your First React Native Application:
  • Creating a new project using Expo or React Native CLI.
  • Running the app on an emulator/simulator or physical device.
  • Understanding the basic project structure.

Section 2: React Native Fundamentals: Components and JSX

• Understanding React Native Components:
  • Differences from web React components.
  • Native components (e.g., View, Text, Image, ScrollView, TextInput).
  • Core components vs. community components.
• JSX in React Native:
  • Similar to web React, but with native components.
  • Embedding JavaScript expressions.
• Styling in React Native:
  • Using StyleSheet.create for creating styles.
  • Differences from CSS (no cascading, camelCase properties).
  • Flexbox for layout.
  • Styling components with the style prop.

Section 3: State and Event Handling in React Native

• Understanding State:
  • Similar concept to web React.
  • Managing data that changes within a component.
• Using State with Functional Components (React Hooks):
  • useState Hook.
  • Updating state.
• Event Handling:
  • Handling user interactions (button presses, text input changes).
  • Common event props (e.g., onPress, onChangeText).
• Conditional Rendering:
  • Rendering different UI based on conditions.
• List Rendering:
  • Using FlatList and SectionList for efficient list rendering.
  • Understanding the importance of the key prop.

Section 4: Navigation in React Native

• Understanding Mobile App Navigation Patterns:
  • Stack Navigation.
  • Tab Navigation.
  • Drawer Navigation.
• Using React Navigation:
  • Installing react-navigation and its dependencies.
  • Setting up navigators (Stack, Tab, Drawer).
  • Navigating between screens.
  • Passing parameters between screens.
  • Customizing navigation headers and options.

Section 5: Working with Native Device Features

• Accessing Device APIs:
  • Camera.
  • Gallery/Photos.
  • Geolocation.
  • Sensors (accelerometer, gyroscope - if needed).
• Using Community Libraries for Native Features:
  • react-native-camera.
  • react-native-image-picker.
  • react-native-geolocation-service.
• Linking Native Modules (for React Native CLI projects).

Section 6: Fetching Data in React Native

• Fetching Data with fetch API:
  • Similar to web React.
  • Handling asynchronous operations.
• Fetching Data with Libraries:
  • Axios.
  • React Query (TanStack Query) - can be used in React Native.
• Handling Loading, Error, and Success States.
• Using useEffect for Data Fetching.

Section 7: State Management (Beyond Component State)

• The Need for Global State Management.
• Context API:
  • Creating and consuming context.
  • Using useContext Hook.
• Introduction to Redux (Optional but Recommended):
  • Core concepts: Store, Actions, Reducers.
  • Using react-redux.
  • Using Redux Toolkit (recommended).
• Introduction to Other State Management Libraries (Optional):
  • Zustand, Jotai, etc.

Section 8: Working with Forms and User Input

• Using TextInput.
• Handling Text Input Changes.
• Managing Form State.
• Basic Form Validation.

Section 9: Advanced Styling and Layout

• More on Flexbox.
• Positioning Elements.
• Working with Dimensions (Dimensions API).
• Platform-Specific Styling.
• Using Styled Components or other CSS-in-JS libraries.

Section 10: Handling Assets and Images

• Using Local Images.
• Using Network Images.
• Image Resizing and Caching.
• Using Icons (e.g., react-native-vector-icons).

Section 11: Debugging and Performance

• Using the React Native Debugger.
• Debugging with Chrome Developer Tools.
• Performance Monitoring.
• Identifying and Fixing Performance Issues.
• Using React.memo, useMemo, useCallback for optimization.

Section 12: Building and Deploying Your App

• Building for Production (Android and iOS).
• Signing Your App.
• Deploying to App Stores (Google Play Store and Apple App Store).
• Using Expo for Easier Building and Deployment (if using Expo).

Section 13: Integrating with Native Code (for React Native CLI)

• Understanding Native Modules.
• Creating Simple Native Modules (Optional, but helpful).

Section 14: Advanced Topics and Ecosystem

• Animations (Animated API, Reanimated).
• Gestures (PanResponder, React Native Gesture Handler).
• Working with Offline Data (Async Storage, SQLite, Realm).
• Push Notifications.
• Authentication and Authorization.
• Testing React Native Applications.
• Using TypeScript with React Native.

Section 15: Projects and Specialization

• Build a Small Mobile App Project:
  • A simple to-do list app.
  • A weather app.
  • A recipe app.
• Explore Specific Areas:
  • Building a social media app clone.
