🔌 Extensibility & Plugins

ZIP Wizard is designed for extensibility. You can add custom functionality through:

Adding Archive Format Handlers

// server/formats/custom-format.ts
import { FormatHandler } from '../lib/format-handler';

export class CustomFormatHandler implements FormatHandler {
  canHandle(buffer: Buffer): boolean {
    return buffer.toString('hex', 0, 4) === 'cafebabe';
  }

  async parse(buffer: Buffer): Promise<ArchiveMetadata> {
    // Your parsing logic
  }
}

// Register in server/index.ts
registerFormatHandler(new CustomFormatHandler());

Adding Custom Vulnerability Scanners

// server/scanners/custom-scanner.ts
export class CustomScanner implements VulnerabilityScanner {
  async scan(file: FileEntry): Promise<ScanResult> {
    // Your scanning logic
    return {
      threats: [],
      severity: 'none',
      recommendations: [],
    };
  }
}

Adding AI Analysis Plugins

// server/ai/custom-analyzer.ts
export class CustomAnalyzer implements AIAnalyzer {
  async analyze(files: FileEntry[]): Promise<Insights> {
    // Your AI analysis logic
  }
}

Plugin Development Guide: See PLUGIN_GUIDE.md for detailed examples and best practices.

❓ FAQ & Troubleshooting

Common Issues

Q: Upload fails with "File too large"

# Increase upload limit in .env
MAX_UPLOAD_SIZE=500MB

Q: Extraction is slow for large archives

Enable streaming mode (default for archives >100MB)
Increase memory allocation: NODE_OPTIONS=--max-old-space-size=4096
Use SSD storage for better I/O performance

Q: Circuit breaker is blocking operations

Check /status dashboard for error details
Review audit logs: npm run logs:audit
Manual reset: curl -X POST http://localhost:5000/api/circuit-breaker/reset

Q: Vulnerability scanner shows false positives

Adjust scan sensitivity in Settings → Security
Add exceptions for known-safe patterns
Submit feedback to improve detection

Q: Tests are failing

# Clear test cache
rm -rf node_modules/.vitest
npm run test:run
