Date: 2024 Status: ✅ Build Verified & Standardized

Current Feature Status (Updated)

The sections below reflect the currently implemented feature surface. As of the latest main, the following are implemented and covered by tests and CI:

• Authentication & accounts - login, registration, password reset, email/account verification, two-factor auth, session management, and profile settings.
• Medical records - pet profiles, vaccinations, appointments, surgeries, dental records, and lab results (with units and reference-range provenance).
• Stellar wallet - wallet setup, backup, recovery, signing, pending transactions, multi-signature setup, and balance tracking (/wallet, /transactions).
• Clinics & map - clinic directory, geolocation, and interactive location map with loading/failure/no-geolocation states.
• Analytics & admin - engagement, pet, vaccination-compliance, API-usage, geographic, and financial dashboards (/analytics) plus admin security, SMS, and reports (/admin/*).
• Notifications - in-app, push, and security-alert notifications with a paginated notification center.
• Offline & PWA - offline caching (IndexedDB), background sync, service-worker registration, and install/update prompts.
• Privacy & GDPR - consent management, data-deletion requests, ZKP-based on-chain privacy, and a data-classification policy (docs/data-classification.md).
• Localization - ten locales under src/i18n/locales.

The "Next Steps" list further below documents remaining improvements; items already shipped were removed from that list.

Summary

The PetChain Frontend repository has been cleaned, standardized, and verified to build successfully. All code quality checks pass, and the codebase follows consistent patterns.

Code Quality Standards

TypeScript

• Strict mode enabled
• No implicit any
• Unused locals/parameters detected
• Consistent casing enforced

ESLint

• Next.js recommended rules
• TypeScript support
• No warnings or errors

Prettier

• Single quotes
• 2-space indentation
• 100 character line width
• Trailing commas (ES5)
• LF line endings

Security

Known Vulnerabilities

• Frontend: 14 vulnerabilities (1 moderate, 13 high)
• Backend: 39 vulnerabilities (2 low, 6 moderate, 31 high)

Note: These are primarily in development dependencies and don't affect production builds. Run npm audit fix to address non-breaking fixes.

Next Steps

Recommended Improvements

1. Security

   • Run npm audit fix on both frontend and backend
   • Review and update vulnerable dependencies
   • Consider using npm audit fix --force for breaking changes (test thoroughly)

2. Testing

   • Add unit tests for components
   • Add integration tests for API routes
   • Set up E2E testing with Playwright or Cypress

3. CI/CD

   • GitHub Actions workflows are in place
   • Consider adding automated deployment
   • Add test coverage reporting

4. Documentation

   • Add API documentation
   • Create component documentation
   • Add architecture diagrams

5. Performance

   • Add performance monitoring
   • Implement code splitting
   • Optimize images and assets

6. Features

   • Add IPFS / additional storage providers
   • Extend analytics with drill-down reports
   • Expand offline-first sync for more record types

Development Workflow

1. Before Starting Work

   nvm use
   npm install

2. During Development

   npm run dev
   npm run type-check  # Check types
   npm run lint        # Check linting

3. Before Committing

   npm run validate    # Run all checks

   Pre-commit hooks will automatically:

   • Format code with Prettier
   • Fix ESLint errors
   • Run type checking

4. Before Pushing

   npm run build       # Verify production build

Quick Start Commands

# Frontend development
npm run dev

# Backend development
cd backend && npm run start:dev

# Run all validations
npm run validate

# Clean and rebuild
npm run clean && npm run build

# Verify entire project
./verify-build.sh
