NestJS Hexagonal Architecture + CQRS | Full Project

1h 23m 52s
English

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.

Frequently asked questions

What are the prerequisites for enrolling in this course?
The course assumes a basic understanding of JavaScript and web development. Familiarity with backend development concepts and Node.js will be beneficial. Prior experience with NestJS is not required but will help in understanding the framework-specific implementations covered in the course.
What will I build during the course?
Students will develop a full-fledged backend project using NestJS, structured around hexagonal architecture and the CQRS pattern. The project focuses on creating a clean, maintainable system with properly structured code reflecting core business logic, application services, and infrastructure adapters. This approach ensures a professional level backend system design.
Who is the target audience for this course?
This course is designed for backend developers and software architects interested in learning about advanced architectural patterns like hexagonal architecture and CQRS. It is suitable for those aiming to enhance their skills in building maintainable and testable systems using NestJS.
How does this course differ from other NestJS courses?
Unlike introductory NestJS courses, this one focuses on implementing advanced architectural patterns like hexagonal architecture and CQRS. It emphasizes structuring code for maintainability and testability, leveraging event-driven processes and dependency inversion, making it more suited for developers looking to build production-level backend systems.
What specific tools or platforms will I learn to use?
The course centers on using NestJS as the primary framework, with an emphasis on applying hexagonal architecture and the CQRS pattern. Students will learn to separate commands and queries and implement event-driven processes, which are crucial for building scalable and maintainable backend systems.
What topics are not covered in this course?
The course does not cover frontend development, database management, or detailed deployment strategies. Its focus is strictly on backend system design using NestJS, hexagonal architecture, and CQRS. Students looking to learn about client-side technologies or specific database implementations will need to seek additional resources.
What is the expected time commitment for completing the course?
The course consists of a single lesson with a runtime of 00:00:00, indicating that it is likely concise. However, the depth and complexity of the topics suggest students should allocate additional time for practical exercises and project work to fully grasp the architectural concepts presented.
