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).
