comprehensive logging solution implemented for both backend and frontend of the GenAI Portfolio application. + +## Overview + +The logging system captures: +- **Backend**: All HTTP requests/responses, user actions, errors, and application flow +- **Frontend**: User interactions, API calls, navigation, and errors + +## Backend Logging + +### Architecture + +The backend uses Python's built-in `logging` module with the following features: + +1. **File-based logging** with daily rotation (14 days retention) +2. **Console logging** for container/development environments +3. **Request/Response middleware** for comprehensive HTTP logging +4. **Structured log messages** with categorization + +### Log Location + +- **File**: `/var/log/genai-portfolio/app.log` +- **Rotation**: Daily at UTC midnight +- **Format**: `YYYY-MM-DDTHH:MM:SSZ LEVEL MODULE MESSAGE` + +### Log Categories + +Backend logs use tagged categories for easy filtering: + +- `[REQUEST]` - Incoming HTTP requests +- `[RESPONSE]` - Outgoing HTTP responses +- `[USER_ACTION]` - User-initiated actions (generate, tests, docs, etc.) +- `[SUCCESS]` - Successful operations +- `[ERROR]` - Errors and exceptions +-

Logging + +### Architecture + +The frontend uses a custom TypeScript logger utility (`src/lib/logger.ts`) with: + +1. **Console logging** with colored output by severity +2. **In-memory log buffer**

- Development-only verbose logging +- `INFO` - General informational messages +- `WARN` - Warnings and potential issues +- `ERROR` - Errors and exceptions + +### Log Categories + +Frontend logs use

logger provides the following methods: + +```typescript +// Basic logging +logger.info(category: string, message: string, data?: any) +logger.warn(category: string, message: string, data?: any) +logger.error(category: string, message: string, error?: Error, data?: any) +logger.debug(category: string, message: string, data?: any) // Dev only + +// Specialized logging +logger.userAction(action: string, details?: any) +logger.apiRequest(method: string, url: string, data?: any) +logger.apiResponse(method: string, url: string, status: number, duration: number, data?:

+logger.clearLogs() // Clear log buffer +logger.exportLogs() // Export as JSON +``` + +### Automatic Logging + +Several logging features are automatic: + +1. **HTTP Interceptors** (`src/lib/http.ts`): + - All API requests/responses logged automatically + - Request duration tracked + - Sensitive data (API keys) redacted + +2. **Router Guards** (`src/router.ts`): + - Navigation events logged automatically + - Route loading errors captured + +3. **Global Error Handlers** (`src/main.ts`): + - Uncaught errors logged + - Unhandled promise rejections logged + +4. **Component Integration**: + - User actions in code generator logged + - Button clicks, form submissions tracked + +## Security Considerations + +### Sensitive Data Protection + +Both backend and frontend implementations protect sensitive data: + +1. **API Keys**: Automatically redacted in frontend logs +2. **User Content**: Only metadata logged (lengths, types), not full content +3. **Stack Traces**: Only included for errors, not routine operations + +### Example of Data Sanitization + +```typescript +// Before logging +const data = { prompt: "...", api_key: "sk-1234567890" } + +// After sanitization +const sanitizedData = { prompt: "...", api_key: "[REDACTED]" } +``` + +## Viewing Logs + +### Backend Logs + +**Development (local)**: +```bash +# View live logs +tail -f /var/log/genai-portfolio/app.log + +# View with grep for filtering +tail -f /var/log/genai-portfolio/app.log | grep ERROR +tail -f /var/log/genai-portfolio/app.log | grep USER_ACTION +``` + +**Production (Docker)**: +```bash +# Container logs (stdout) +docker compose logs -f backend + +# File logs (if volume mounted) +docker compose exec backend tail -f /var/log/genai-portfolio/app.log +``` + +### Frontend Logs + +**Browser

Backend Log Patterns + +```bash +# Find all errors +grep ERROR /var/log/genai-portfolio/app.log + +# Find specific user action +grep "\[USER_ACTION\]\[generate\]" /var/log/genai-portfolio/app.log + +#

+ +### Frontend Console Filtering + +In browser DevTools Console: +- Use the filter box to search for specific categories +- Filter by log level (Info, Warnings, Errors) +- Use browser's search (Ctrl+F) to find specific messages + +## Troubleshooting + +### Backend Issues + +**Problem**: Logs not appearing in file +**Solution**: Check permissions on `/var/log/genai-portfolio` directory + +**Problem**: Too many logs +**Solution**: Adjust log level in `app/main.py`: `logger.setLevel(logging.WARNING)` + +### Frontend Issues + +**Problem**: Logs not appearing in console +**Solution**: Check browser console is open and not filtered + +**Problem**: Too verbose in production +**Solution**: DEBUG logs only appear in development mode + +## Future Enhancements + +Potential improvements for the logging system: + +1. **Remote Logging**: Send frontend logs to backend/analytics service +2. **Log Aggregation**: Integration with tools like Elasticsearch, Splunk +3. **Metrics Dashboard**: Real-time visualization of log data +4. **Structured Logging**: JSON-formatted logs for better parsing +5. **User Session Tracking**: Associate logs with user sessions +6. **Performance Metrics**: Track and log performance data +7. **Log Sampling**: Sample high-volume logs in production + +## Best Practices + +1. **Don't log sensitive data**: Never log passwords, tokens, full API keys +2. **Log context**: Include relevant context (request IDs, user actions) +3. **Use appropriate levels**: ERROR for failures, INFO for actions, DEBUG for details +4. **Be consistent**: Use established categories and patterns +5. **Keep it readable**: Format messages clearly and consistently +6. **Monitor log size**: Ensure rotation and retention policies are working + +## References + +- Backend
