⚠️ Known Issues & Limitations

Frontend Web Security

9 vulnerabilities remain (all in development dependencies):

  • 6 high severity (nth-check, svgo chain)
  • 3 moderate severity (postcss, webpack-dev-server)

Why they remain:

  • All vulnerabilities are in dev dependencies only (not in production)
  • Fixing them would require breaking changes to react-scripts
  • react-scripts 5.0.1 is the latest stable version
  • Production builds are completely safe

Impact:

  • ❌ Does NOT affect production builds
  • ❌ Does NOT affect end users
  • ⚠️ Only affects development server (local development)

Recommendations:

  • Accept the risk (recommended for now)
  • Future consideration: Migrate to Vite for better security

Mobile App Warnings

Remaining Deprecation Warnings: Some deprecation warnings may still appear from:

  • babel-preset-expo - Uses proposal plugins (Expo will update in future SDK)
  • inflight - Deeply nested transitive dependency

Why they remain:

  • These come from Expo's dependencies
  • They don't affect functionality or security
  • Will be resolved when Expo updates dependencies

Impact:

  • ❌ No functional impact
  • ❌ No security impact
  • ⚠️ Just deprecation warnings

Packages Not Updated (By Design)

These packages show newer versions but are intentionally kept at current versions for Expo 54 compatibility:

  • React Navigation v7 - Available but requires Expo SDK 52+
  • React 19 - Already updated to latest
  • React Native 0.82 - Available but requires newer Expo SDK
  • Expo Router 6 - Already at latest for Expo 54

Reason: Expo SDK 54 has specific version requirements. Updating these would break compatibility.

📊 Package Status Summary

Web App

  • ✅ All user-facing dependencies updated
  • ✅ All testing libraries updated
  • ✅ Modern Babel plugins added

Mobile App

🚀 Next Steps

  1. Test the applications to ensure everything works:

    # Web app
cd frontend-web
npm start

# Mobile app
cd frontend-mobile
npx expo start

  2. Future consideration: Migrate web app to Vite for:

    • Better security (no vulnerabilities)
    • Faster development experience
    • Modern build tooling

  3. Monitor: Keep an eye on react-scripts updates for security patches

  4. Future Expo Upgrade: Consider upgrading to Expo SDK 55+ when available for latest package versions

📝 Notes

  • React Router v7 was initially updated but reverted to v6.28.0 for stability
  • All deprecated Babel proposal plugins replaced with transform equivalents
  • Mobile app has zero vulnerabilities
  • Web app vulnerabilities are acceptable (dev-only, no production impact)
  • Overrides ensure newer versions of deprecated transitive dependencies
  • Future Expo SDK upgrades will resolve remaining Babel warnings
