🔧 Development Notes

📋 Development Workflow​

Git Workflow​

  • Main Branch: main - Production-ready code
  • Feature Branches: feature/description - New features
  • Hotfix Branches: hotfix/description - Critical fixes
  • Release Branches: release/version - Release preparation

Code Standards​

  • TypeScript: Strict mode enabled
  • ESLint: Google style guide
  • Prettier: Consistent formatting
  • Conventional Commits: Standardized commit messages

Testing Strategy​

  • Unit Tests: Jest for functions, Vitest for frontend
  • Integration Tests: API endpoint testing
  • E2E Tests: Critical user workflows
  • Coverage Target: 80%+ for critical paths

🚀 Development Setup​

Prerequisites​

# Node.js 18+
node --version

# Firebase CLI
npm install -g firebase-tools

# Google Cloud SDK
gcloud --version

Local Development​

# Install dependencies
npm install

# Start frontend
cd vib-frontend && npm run dev

# Start functions emulator
cd functions && npm run serve

# Start Python backend
cd vib-backend && uvicorn main:app --reload

📝 Code Review Guidelines​

Checklist​

  • Code follows style guide
  • Tests are included and passing
  • Documentation is updated
  • No console.log statements
  • Error handling is proper
  • Security considerations addressed

Review Process​

  1. Self-review before requesting review
  2. Request review from 2+ team members
  3. Address feedback and make changes
  4. Approve and merge after approval

🐛 Debugging Tips​

Frontend Debugging​

// Enable React DevTools
// Use browser dev tools for network issues
// Check console for errors and warnings

Backend Debugging​

# View function logs
firebase functions:log

# Test functions locally
firebase functions:shell

# Debug with VS Code
// Attach debugger to running process

Database Debugging​

// Use Firestore emulator
firebase emulators:start --only firestore

// Check security rules
firebase firestore:rules:test

📊 Performance Optimization​

Frontend Performance​

  • Code Splitting: Lazy load routes and components
  • Bundle Analysis: Use webpack-bundle-analyzer
  • Image Optimization: WebP format, lazy loading
  • Caching: Service workers for offline support

Backend Performance​

  • Connection Pooling: Reuse database connections
  • Caching: Redis for frequently accessed data
  • Async Processing: Non-blocking operations
  • Database Indexing: Optimize Firestore queries

🔒 Security Development​

Authentication​

  • Always verify Firebase ID tokens
  • Validate user permissions
  • Use role-based access control
  • Implement proper session management

Data Validation​

  • Validate all input parameters
  • Sanitize user inputs
  • Use proper data types
  • Implement rate limiting

Secrets Management​

  • Use Firebase Functions secrets
  • Never hardcode API keys
  • Rotate secrets regularly
  • Use environment variables
