# PayGuard Frontend
|
||||
|
||||
A modern React web application for testing and interacting with the PayGuard fraud detection API.
|
||||
|
||||
## Features
|
||||
|
||||
✨ **Core Features:**
|
||||
- 🔐 JWT Token Generation - Securely authenticate with the API
|
||||
- 📤 Transaction Submission - Send transactions for fraud detection
|
||||
- 📊 Real-time Results - View transaction processing status
|
||||
- 🎯 Pre-built Scenarios - Quick test cases with common fraud patterns
|
||||
- 📱 Responsive Design - Works on desktop and mobile devices
|
||||
|
||||
## Technology Stack
|
||||
|
||||
- **Framework**: React 18 with TypeScript
|
||||
- **Build Tool**: Vite (lightning-fast development)
|
||||
- **HTTP Client**: Axios
|
||||
- **UI Icons**: Lucide React
|
||||
- **Styling**: CSS3 with CSS Variables
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Node.js 16+ (for development)
|
||||
- PayGuard API running on `localhost:8000`
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
cd frontend
|
||||
npm install
|
||||
```
|
||||
|
||||
## Running the Application
|
||||
|
||||
### Development Mode
|
||||
|
||||
```bash
|
||||
npm run dev
|
||||
```
|
||||
|
||||
Opens automatically at `http://localhost:3000`
|
||||
|
||||
### Production Build
|
||||
|
||||
```bash
|
||||
npm run build
|
||||
```
|
||||
|
||||
Creates optimized build in `dist/` directory
|
||||
|
||||
### Preview Production Build
|
||||
|
||||
```bash
|
||||
npm run preview
|
||||
```
|
||||
|
||||
## API Integration
|
||||
|
||||
The frontend connects to the PayGuard API with these endpoints:
|
||||
|
||||
| Endpoint | Method | Purpose |
|
||||
|----------|--------|---------|
|
||||
| `/token` | POST | Generate JWT authentication token |
|
||||
| `/transaction` | POST | Submit transaction for fraud analysis |
|
||||
| `/health` | GET | Check API health status |
|
||||
|
||||
### Example API Call
|
||||
|
||||
```typescript
|
||||
// Generate token
|
||||
POST http://localhost:8000/token?user_id=user_123
|
||||
|
||||
// Submit transaction
|
||||
POST http://localhost:8000/transaction
|
||||
Headers: Authorization: Bearer <token>
|
||||
Body: {
|
||||
"amount": 100.00,
|
||||
"merchant": "Starbucks",
|
||||
"description": "Coffee purchase"
|
||||
}
|
||||
```
|
||||
|
||||
## Using the Frontend
|
||||
|
||||
### 1. Generate Authentication Token
|
||||
|
||||
- Enter or accept the auto-generated User ID
|
||||
- Click "Generate Token" button
|
||||
- Token is now ready for API calls
|
||||
|
||||
### 2. Select a Test Scenario (Optional)
|
||||
|
||||
Choose from pre-built scenarios:
|
||||
- **Normal Transaction**: $75.50 at Starbucks
|
||||
- **Large Purchase**: $8,500 at unknown merchant
|
||||
- **Grocery Shopping**: $120 at Target
|
||||
- **Online Shopping**: $299.99 at Amazon
|
||||
- **Gas Station**: $45.20 at Shell
|
||||
|
||||
Or manually enter transaction details.
|
||||
|
||||
### 3. Submit Transaction
|
||||
|
||||
- Enter amount, merchant, and description
|
||||
- Click "Submit Transaction"
|
||||
- View result in the Results section below
|
||||
|
||||
### 4. View Results
|
||||
|
||||
Transaction results display:
|
||||
- Transaction ID (shortened for readability)
|
||||
- Status (accepted)
|
||||
- Submission timestamp
|
||||
|
||||
## Component Architecture
|
||||
|
||||
```
|
||||
App.tsx
|
||||
├── Authentication Section
|
||||
│ ├── User ID input
|
||||
│ ├── Token generation button
|
||||
│ └── Token display
|
||||
├── Transaction Section
|
||||
│ ├── Preset scenarios
|
||||
│ ├── Transaction form
|
||||
│ │ ├── Amount input
|
||||
│ │ ├── Merchant input
|
||||
│ │ └── Description input
|
||||
│ └── Submit button
|
||||
├── Status Alerts
|
||||
│ ├── Error messages
|
||||
│ └── Success messages
|
||||
├── Results Section
|
||||
│ └── Transaction results list
|
||||
└── API Info Section
|
||||
└── Connection status & endpoints
|
||||
```
|
||||
|
||||
## State Management
|
||||
|
||||
The application uses React hooks for state:
|
||||
|
||||
```typescript
|
||||
// Authentication state
|
||||
const [auth, setAuth] = useState<AuthState>({
|
||||
token: null,
|
||||
userId: string,
|
||||
isAuthenticated: boolean
|
||||
});
|
||||
|
||||
// Transaction form state
|
||||
const [transaction, setTransaction] = useState<Transaction>({
|
||||
amount: number,
|
||||
merchant: string,
|
||||
description: string
|
||||
});
|
||||
|
||||
// Results history
|
||||
const [results, setResults] = useState<Result[]>([]);
|
||||
|
||||
// UI state
|
||||
const [loading, setLoading] = useState(false);
|
||||
const [error, setError] = useState<string | null>(null);
|
||||
const [success, setSuccess] = useState<string | null>(null);
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
The application handles common errors:
|
||||
|
||||
- **Connection Error**: "Failed to generate token. Is the API running?"
|
||||
- **Auth Error**: "Please generate a token first"
|
||||
- **API Errors**: Display server error messages
|
||||
|
||||
## Styling
|
||||
|
||||
The application uses:
|
||||
- **CSS Variables** for consistent theming
|
||||
- **CSS Grid** for responsive layouts
|
||||
- **Flexbox** for component alignment
|
||||
- **Transitions** for smooth interactions
|
||||
|
||||
### Color Palette
|
||||
|
||||
```css
|
||||
--primary: #3b82f6 /* Blue */
|
||||
--success: #10b981 /* Green */
|
||||
--error: #ef4444 /* Red */
|
||||
--warning: #f59e0b /* Yellow */
|
||||
--text: #1f2937 /* Dark Gray */
|
||||
--bg: #f9fafb /* Light Gray */
|
||||
```
|
||||
|
||||
## Development
|
||||
|
||||
### Adding New Features
|
||||
|
||||
1. Create new components in `src/components/`
|
||||
2. Import and use in `App.tsx`
|
||||
3. Update styling in `src/App.css`
|
||||
|
||||
### Building for Production
|
||||
|
||||
```bash
|
||||
npm run build
|
||||
npm run preview
|
||||
```
|
||||
|
||||
The `dist/` folder can be served by any static file server.
|
||||
|
||||
## Deployment
|
||||
|
||||
### Docker Deployment
|
||||
|
||||
Create `Dockerfile`:
|
||||
```dockerfile
|
||||
FROM node:18-alpine as build
|
||||
WORKDIR /app
|
||||
COPY . .
|
||||
RUN npm ci && npm run build
|
||||
|
||||
FROM node:18-alpine
|
||||
WORKDIR /app
|
||||
RUN npm install -g serve
|
||||
COPY --from=build /app/dist ./dist
|
||||
EXPOSE 3000
|
||||
CMD ["serve", "-s", "dist", "-l", "3000"]
|
||||
```
|
||||
|
||||
Build and run:
|
||||
```bash
|
||||
docker build -t payguard-frontend .
|
||||
docker run -p 3000:3000 payguard-frontend
|
||||
```
|
||||
|
||||
### Vercel Deployment
|
||||
|
||||
```bash
|
||||
npm install -g vercel
|
||||
vercel
|
||||
```
|
||||
|
||||
### Netlify Deployment
|
||||
|
||||
1. Connect GitHub repository
|
||||
2. Set build command: `npm run build`
|
||||
3. Set publish directory: `dist`
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### API Connection Issues
|
||||
|
||||
1. Verify API is running: `curl http://localhost:8000/health`
|
||||
2. Check that port 8000 is not blocked
|
||||
3. Ensure API CORS is configured (if running on different domain)
|
||||
|
||||
### Token Generation Fails
|
||||
|
||||
- Verify API is running and healthy
|
||||
- Check browser console for detailed error messages
|
||||
- Ensure User ID is not empty
|
||||
|
||||
### Transactions Not Submitting
|
||||
|
||||
- Verify token has been generated
|
||||
- Check that merchant name is not empty
|
||||
- Review browser console for API error messages
|
||||
|
||||
## API Documentation
|
||||
|
||||
Full API documentation available at `/Users/pat/Projects/PAT/payguard-poc/README_IMPLEMENTATION.md`
|
||||
|
||||
## Architecture Diagram
|
||||
|
||||
See `payguard_fraud_detection_flowchart.svg` for the complete system architecture.
|
||||
|
||||
## Performance
|
||||
|
||||
- **Initial Load**: < 1 second (Vite optimizations)
|
||||
- **API Calls**: < 200ms (local network)
|
||||
- **State Updates**: Instant (React optimization)
|
||||
|
||||
## Browser Support
|
||||
|
||||
- Chrome 90+
|
||||
- Firefox 88+
|
||||
- Safari 14+
|
||||
- Edge 90+
|
||||
|
||||
## Future Enhancements

||||
|
||||
- [ ] Real-time transaction status polling
|
||||
- [ ] Redis result lookup
|
||||
- [ ] User profile visualization
|
||||
- [ ] Transaction history export
|
||||
- [ ] Dark mode
