🌐 Context Annotations

Our project uses inline comment-based context annotations to provide clear, standardized documentation for context providers.

Annotation Format

Context annotations follow this pattern:

// @context: propertyName - type - description

Why Context Annotations?

1. Self-Documenting Code: Inline comments provide immediate context
2. Easy Documentation: Annotations can be parsed for automatic documentation
3. Developer Experience: Quickly understand context properties

Real-World Examples

Network Context

// @context: isConnected - boolean - true if the device is connected to the internet, false otherwise
// @context: connectionType - string - the type of connection the device is using (wifi, cellular, etc.)
// @context: networkDetails - NetInfoState - the details of the network connection
const NetworkContext = createContext<NetworkContextType>({
  isConnected: true,
  connectionType: null,
  networkDetails: null
});

Theme Context

// @context: isDarkMode - boolean - true if the device is in dark mode, false otherwise
// @context: toggleTheme - function - toggles the theme between dark and light
const ThemeContext = createContext<ThemeContextType>({
  isDarkMode: false,
  toggleTheme: () => {}
});

Generating Context Metadata

Context metadata is automatically generated using a custom script:

# Manually generate context metadata
node scripts/generate-context-metadata.js

# Or simply start the app (script runs automatically)
npm start

🏁 Getting Started

# Create a new project using this template
npx create-expo-app my-app --template expo-template-elink

# Or clone the repository for development
git clone https://github.com/Valentine8342/Expo-Starter-Kit.git

# Install dependencies
npm install

# Start the development server
npm start

# Run on iOS simulator
npm run ios

# Run on Android emulator
npm run android

📦 Available Scripts

• npm start: Start the Expo development server (generates context metadata)
• npm run ios: Run on iOS simulator
• npm run android: Run on Android emulator
