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.
- Using
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
andSectionList
for efficient list rendering. - Understanding the importance of the
key
prop.
- Using
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.
- Installing
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
