npm run watch:extension

# Build options page only
npm run build

# Copy extension files only
npm run copy:extension
```

└── background.js # Service worker
```

## 💻 Usage

### Popup Interface:
- Click the Interzept icon in Chrome toolbar
- Toggle extension on/off
- View active rules and statistics
- Access rule cards for quick actions
- Click "Open Interzept Options" for full interface

### Options Page:
- Right-click extension icon → "Options"
- Or click "Open Interzept Options" from popup
- Create and manage interception rules
- Configure request/response modifications
- Set up API mocking and redirects

## 🔧 Configuration

### Rule Types:
- **Override**: Replace API responses with custom data
- **Redirect**: Redirect requests to different URLs
- **Headers**: Modify request/response headers
- **CORS**: Bypass cross-origin restrictions
- **Mock**: Create fake API endpoints

### Storage:
- Rules are stored in Chrome sync storage
- Settings persist across Chrome sessions
- Automatic backup and restore

## 🤝 Contributing

1. Fork the repository
2. Create a feature branch: `git checkout -b feature/amazing-feature`
3. Make your changes and test thoroughly
4. Build the extension: `npm run build:extension`
5. Test in Chrome with the built extension
6. Commit your changes: `git commit -m 'Add amazing feature'`
7. Push to the branch: `git push origin feature/amazing-feature`
8. Open a Pull Request

## 📝 Version History

- **v25.6.4**: Major restructuring - eliminated duplicate code, hybrid architecture
- **v1.0.1**: Initial Chrome extension release

## 🐛 Troubleshooting

### Common Issues:
- **Popup not showing**: Check if extension is enabled in chrome://extensions/
- **Rules not working**: Verify extension has permissions for the target website
- **Build errors**: Ensure all dependencies are installed with `npm install`

### Debug Mode:
1. Enable "Developer mode" in chrome://extensions/
2. Use "Inspect popup" to debug popup issues
3. Check browser console for error messages
4. Use source maps for debugging built code

# Interzept Extension Restructuring Summary

## ✅ Completed Tasks

### 1. **Eliminated Duplicate Code**
- **Removed**: `src/App.tsx` (955-line duplicate)
- **Removed**: `src/index.tsx` (unused entry point)
- **Removed**: `src/pages/` folder (unnecessary structure)
- **Kept**: Only the options page as the main interface

### 2. **Created Shared Architecture**
- **`src/shared/types/rules.ts`**: Centralized type definitions
- `Rule` interface and related types
- `RuleType`, `HttpMethod`, `ResponseType` enums
- **`src/shared/utils/helpers.ts`**: Common utility functions
- Mobile detection, ID generation, URL validation, date formatting
- **`src/shared/utils/storage.ts`**: Chrome storage abstraction
- Unified storage interface with localStorage fallback
- **`src/shared/hooks/useRules.ts`**: Rules management hook
- Centralized rules state management

### 3. **Implemented Simple Popup Launcher**
- **`src/popup/Popup.tsx`**: Feature-rich popup interface
- Shows active rules count and quick stats
- Displays recent rules with toggle functionality
- "Open Interzept Options" button to launch full interface
- **`src/popup/index.tsx`**: Popup entry point
- **`src/popup/index.html`**: Popup HTML template

### 4. **Updated Build Configuration**
- **`vite.config.ts`**: Multi-entry build setup
- Separate entry points for popup and options
- Proper path mapping with `@/` alias
- **`scripts/prepare-extension.js`**: Enhanced build script
- Generates both `popup.html` and `options.html`
- Maintains proper Chrome extension structure

### 5. **Fixed Technical Issues**
- **Options.tsx**: Fixed malformed JSX syntax
- **Popup.tsx**: Added Chrome API type declarations
- **Import paths**: Updated to use shared utilities and `@/` mapping

## 🏗️ Final Structure

```
src/
├── shared/ # Shared code and utilities
│ ├── types/
│ │ └── rules.ts # Type definitions
│ ├── utils/
│ │ ├── helpers.ts # Common utilities
│ │ └── storage.ts # Storage abstraction
│ └── hooks/
│ └── useRules.ts # Rules management
├── popup/ # Simple popup launcher
│ ├── Popup.tsx # Feature-rich popup interface
│ ├── index.tsx # Entry point
│ └── index.html # HTML template
└── options/ # Full options interface
├── Options.tsx # Main options page (original App.tsx)
├── index.tsx # Entry point
└── index.html # HTML template
```

## 🎯 Key Benefits

1. **Zero Duplication**: Eliminated 955 lines of duplicate code
2. **Better Organization**: Clear separation of concerns with shared utilities
3. **Improved UX**: Quick popup for common actions, full interface for configuration
4. **Maintainability**: Centralized type definitions and shared logic
5. **Chrome Extension Compliance**: Proper manifest configuration and structure

## 🚀 Usage

1. **Build Extension**: `npm run build`
2. **Prepare Package**: `node scripts/prepare-extension.js`
3. **Load in Chrome**: Load the `dist/` folder as unpacked extension

## 📋 Extension Features

- **Popup**: Quick access to rules, stats, and options launcher
- **Options**: Full configuration interface with all original functionality
- **Storage**: Persistent rules storage with Chrome sync
- **Background**: Service worker for request interception
- **Content Script**: Injection for API monitoring
