### ✓ API Endpoints Created
- **GET** `/api/auth/check.php` - Check authentication status
- **GET** `/api/auth/user.php` - Get current user details (requires auth)

### ✓ CORS Configuration
- Configured for React dev server (localhost:5173)
- Configured for production domain (rebusys.uk)
- Supports credentials (sessions/cookies)

### ✓ .htaccess Updated
- API routes configured
- React app routes prepared (commented out for future use)
- Existing PHP pages continue to work

### ✓ Environment Variables
- `.env` file created with API base URL configuration

## How to Use

### Start Development Server
```bash
# On remote server
cd /var/www/rebusys.uk/html/red-desk-v4/react-app
npm run dev
```

### Access Development Server
```bash
# On local machine
ssh -L 5173:localhost:5173 korweb@rebusys.uk

# Then in browser
http://localhost:5173
```

### Build for Production
```bash
# On remote server
cd /var/www/rebusys.uk/html/red-desk-v4/react-app
npm run build
```

### Test API Endpoints
```bash
# Check auth status
curl https://rebusys.uk/red-desk-v4/api/auth/check.php

# Get current user (requires login)
curl https://rebusys.uk/red-desk-v4/api/auth/user.php
```

## API Usage Examples

### In React Components
```javascript
import axios from 'axios';

// Create axios instance with base URL
const api = axios.create({
  baseURL: import.meta.env.VITE_API_BASE_URL,
  withCredentials: true // Important for session cookies
});

// Check authentication
const checkAuth = async () => {
  const response = await api.get('/auth/check.php');
  return response.data;
};

// Get current user
const getCurrentUser = async () => {
  const response = await api.get('/auth/user.php');
  return response.data;
};
```

### API Response Helpers Available
- `successResponse($data, $message, $statusCode)` - Send success response
- `errorResponse($error, $statusCode, $details)` - Send error response
- `validationErrorResponse($errors)` - Send validation errors
- `notFoundResponse($message)` - Send 404 response
- `unauthorizedResponse($message)` - Send 401 response
- `forbiddenResponse($message)` - Send 403 response

### Authentication Middleware Functions
- `requireAuth()` - Require user to be logged in
- `getCurrentUser()` - Get current user or null
- `hasRole($roles)` - Check if user has specific role(s)
- `requireRole($roles)` - Require specific role(s)

## Next Steps

According to the migration plan, you should now proceed to:

### Phase 1: Core Infrastructure (Week 3-4)
- Build reusable React components (Layout, DataTable, Form components, Modal)
- Create common API endpoints (client lists, contacts, engineers)
- Set up React Router configuration

### Phase 1a: Authentication System (if needed)
- Create new authentication system that works with both PHP and React
- OR continue using existing ASEngine authentication (currently configured)

### Phase 2: First Migration - Dashboard
- Create dashboard API endpoints
- Build React dashboard components
- Migrate dashboard page to React

## Files to Push to Remote Server

Remember to push these files to your remote server:
```bash
git add .
git commit -m "Complete Phase 0.3: Initial Setup Tasks"
git push origin [branch-name]
```

Then on the remote server:
```bash
cd /var/www/rebusys.uk/html/red-desk-v4
git pull
```

## Notes

- Node 16 is sufficient for development, production can use newer versions
- The React build output is static files that don't require Node.js in production
- ESLint warnings can be ignored - they don't affect functionality
- Always use SSH tunnel to access dev server securely
- Database structure should be preserved where possible (per project requirements)

## Support

- React app running: ✓
- API structure created: ✓
- Authentication bridge working: ✓
- CORS configured: ✓

**Status: Phase 0.3 Complete - Ready to begin Phase 1**
