🚀 Next Steps

To Complete Sprint 0:

1. Frontend Configuration Files (Remaining):

   cd apps/frontend
   # Create:
   # - tsconfig.json
   # - next.config.js
   # - tailwind.config.js
   # - postcss.config.js
   # - .env.example
   # - app/ directory structure
   

2. CI/CD Pipeline (Week 2 task):

   # Create .github/workflows/
   # - ci.yml (lint, test, build)
   # - deploy.yml (optional)
   

3. Install Dependencies:

   # Root
   npm install
   
   # Backend
   cd apps/backend && npm install
   
   # Frontend
   cd apps/frontend && npm install
   

4. Start Infrastructure:

   docker-compose up -d
   

5. Verify Setup:

   # Backend
   cd apps/backend
   npm run dev
   # Visit: http://localhost:4000/api/docs
   
   # Frontend
   cd apps/frontend
   npm run dev
   # Visit: http://localhost:3000

   • Environment validation with Joi
   • Structured logging
   • Security best practices
   • Health check endpoints

3. Developer Experience:

• Redis: Runs on port 6379 with password authentication
• API: Backend runs on port 4000, frontend on port 3000
• Swagger: Available at http://localhost:4000/api/docs

🔒 Security Checklist for Production

Before deploying to production:

• Change all default passwords
• Generate strong JWT secret
• Configure OAuth2 credentials
• Setup email service (SendGrid/SES)
• Configure AWS S3 credentials
• Obtain carrier API keys
• Enable HTTPS/TLS
• Configure Sentry for error tracking
• Setup monitoring (Prometheus/Grafana)
• Enable database backups
• Review CORS configuration
• Test rate limiting
• Run security audit

🎉 Sprint 0 Status: NEARLY COMPLETE

The foundation is solid and ready for Phase 1 development (Rate Search & Carrier Integration).

Estimated time to complete remaining tasks: 2-4 hours

Ready to proceed with:

• Domain entity modeling
• Rate search implementation
• Carrier connector development
