Building Scalable Web Apps with Flask and React

By admin • February 05, 2026 • 69 views

Our architecture patterns for building full-stack applications that handle growth — from startup MVP to production platform.

Why Flask + React?

Flask gives you control without the bloat. React provides a component-based UI that scales. Together, they form a stack that's both productive for MVPs and robust enough for production.

Our Architecture Pattern

We typically structure projects with clear separation:

  • Backend: Flask with SQLAlchemy, Marshmallow for serialization
  • Frontend: React with TypeScript, React Query for data fetching
  • API: RESTful endpoints with proper pagination and filtering
  • Auth: JWT with refresh tokens, role-based access control
  • Deploy: Docker containers, Nginx reverse proxy, GitHub Actions CI/CD

Database Patterns

SQLAlchemy is incredibly powerful. We use Alembic for migrations, implement soft deletes for audit trails, and use hybrid properties for computed fields.

Performance Tips

  • Use Redis for session storage and caching
  • Implement database query optimization with eager loading
  • Use Celery for background tasks (email, reports, data processing)
  • Enable gzip compression at Nginx level
