NestJS Hexagonal Architecture + CQRS | Full Project

In this lesson, we will step by step create a full-fledged project using NestJS, with the help of hexagonal architecture and the CQRS pattern.

You will learn how to properly structure the code around the core business logic, application services, and infrastructure adapters to achieve a clean, maintainable, and easily testable system.

We will practically examine the separation of commands and queries, event-driven processes, and dependency inversion—all of this with a real-world example that demonstrates how professional production-level backend systems are designed.
