if (!validation.isValid) { // Handle invalid path } ``` ## 📊 Monitoring & Metrics ### Performance Metrics Track detailed performance metrics: ```typescript const metrics = performanceMonitor.endMonitoring(); console.log(`Duration: ${metrics.duration}ms`); console.log(`Files Processed: ${metrics.filesProcessed}`); console.log(`Total Keys: ${metrics.totalKeys}`); console.log(`Memory Usage: ${metrics.memoryUsage}MB`); console.log(`CPU Usage: ${metrics.cpuUsage}s`); ``` ### Logging with Context Structured logging with context and metadata: ```typescript logger.info('Processing file', 'extraction', { file: 'auth/service.ts', size: '2.5MB', keys: 15 }); ``` ## 🛠️ Configuration Management ### Show Configuration ```bash # Show current configuration translation config show # Show detailed configuration translation config show --verbose ``` ### Validate Configuration ```bash # Validate current configuration translation config validate ``` ### Set Configuration Values ```bash # Set log level translation config set logging.level debug # Set max concurrency translation config set performance.maxConcurrency 8 # Set security settings translation config set security.validateInputs true ``` ### Reset Configuration ```bash # Reset to default configuration translation config reset ``` ## 🔍 Validation System ### Translation Key Validation ```typescript const validation = validator.validateTranslationKey({ key: 'AUTH.USER_EXISTS', text: 'User already exists', type: 'EXCEPTION', file: '/path/to/file.ts', line: 10 }); if (!validation.isValid) { logger.logValidationErrors(validation.errors, 'extraction'); } ``` ### Content Security ```typescript // Detect suspicious content const validation = validator.validateInputString( '<script>alert("xss")</script>', 'user input' ); if (validation.warnings.length > 0) { logger.logValidationWarnings(validation.warnings, 'security'); } ``` ## 📈 Performance Optimization ### Batch Processing Files are processed in configurable batches for optimal performance: ```typescript // Process files in batches of 8 const batchSize = 8; for (let i = 0; i < files.length; i += batchSize) { const batch = files.slice(i, i + batchSize); await Promise.allSettled(batch.map(processFile)); } ``` ### Memory Management Automatic memory usage tracking and optimization: ```typescript const memoryUsage = process.memoryUsage(); const heapUsedMB = memoryUsage.heapUsed / 1024 / 1024; if (heapUsedMB > 100) { logger.warning('High memory usage detected', 'performance'); } ``` ## 🧪 Testing ### Enterprise Feature Tests ```bash # Run enterprise feature tests npm run test:enterprise # Run performance tests npm run performance:test # Run validation tests npm run validation:test ``` ### Security Tests ```bash # Run security audit npm run security:audit # Fix security issues npm run security:fix ``` ## 🔄 CI/CD Integration ### GitHub Actions Example ```yaml name: Translation CLI Tests on: [push, pull_request] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Setup Node.js uses: actions/setup-node@v3 with: node-version: '18' cache: 'npm' - name: Install dependencies run: npm ci - name: Run tests run: npm test - name: Run enterprise tests run: npm run test:enterprise - name: Security audit run: npm run security:audit - name: Build run: npm run build ``` ## 📋 Migration Guide ### From v1.0.0 to v2.0.0 1. **Update package.json**: ```json { "dependencies": { "@onwello/translation-cli": "^2.0.0" } } ``` 2. **Create configuration file**: ```bash translation config show > .translation-cli.json ``` 3. **Update environment variables**: ```bash export NODE_ENV=production export LOG_LEVEL=warn export MAX_CONCURRENCY=8 ``` 4. **Update CI/CD pipelines**: - Add enterprise tests - Add security audits - Add performance monitoring ## 🎯 Best Practices ### Production Deployment 1. **Use production environment**: ```bash NODE_ENV=production translation extract ``` 2. **Enable all security features**: ```bash VALIDATE_INPUTS=true SANITIZE_OUTPUTS=true translation extract ``` 3. **Configure logging**: ```bash LOG_FORMAT=json LOG_OUTPUT=both LOG_FILE=/var/log/translation-cli.log ``` 4. **Set performance limits**: ```bash MAX_CONCURRENCY=8 MAX_FILE_SIZE=50 TIMEOUT=600 ``` ### Development 1. **Use development environment**: ```bash NODE_ENV=development translation extract ``` 2. **Enable verbose logging**: ```bash LOG_LEVEL=debug translation extract -v ``` 3. **Use dry run for testing**: ```bash translation replace --dry-run ``` ## 🆘 Troubleshooting ### Common Issues 1. **High memory usage**: - Reduce `MAX_CONCURRENCY` - Reduce `MAX_FILE_SIZE` - Enable file filtering 2. **Slow processing**: - Increase `MAX_CONCURRENCY` - Check file sizes - Monitor system resources 3. **Validation errors**: - Check input files - Review configuration - Enable verbose logging ### Debug Mode ```bash # Enable debug logging LOG_LEVEL=debug translation extract -v # Show detailed configuration translation config show --verbose # Validate configuration translation config validate ``` ## 📞 Support For enterprise support and custom features: - **Email**: enterprise@onwello.com - **Documentation**: https://docs.onwello.com/translation-cli - **Issues**: https://github.com/onwello/i18n-cli/issues - **Enterprise**: https://onwello.com/enterprise --- **Enterprise-Grade Translation CLI v2.0.0** - Built for scale, security, and performance. 🚀
