Analisi Tracker API - Production-Ready Backend

Complete, production-ready backend API infrastructure for the analisi-tracker medical lab test analytics platform.

Quick Start

# Install dependencies
npm install

# Set up environment
cp .env.api.example .env
# Edit .env with your database URL and secrets

# Set up database
createdb analisi_tracker
npm run db:migrate
npm run db:seed

# Start server
npm run server:dev

Server will be available at http://localhost:3000 API Documentation at http://localhost:3000/api-docs

Security Best Practices

  1. Always use HTTPS in production
  2. Set strong JWT secrets
  3. Configure CORS for production domain only
  4. Enable rate limiting
  5. Regular security updates
  6. Monitor logs for suspicious activity
  7. Use environment variables for secrets
  8. Enable database backups
  9. Implement audit logging
  10. Regular security audits
