NestJS Hexagonal Architecture + CQRS | Full Project

In this lecture, we’ll build a complete NestJS project using Hexagonal Architecture and CQRS from the ground up. You’ll learn how to structure your code around core domain logic, application services, and infrastructure adapters — creating a clean, maintainable, and testable system. We’ll explore command and query separation, event-driven flows, and dependency inversion in practice, culminating in a production-ready example that demonstrates how professional-grade backend systems are designed.
