Overview of this book

This unique ASP.NET Core book will fill in the gaps in your REST API and backend designs. Learn how to build robust, maintainable, and flexible apps using Gang of Four (GoF) design patterns and modern architectural principles. This new edition is updated for .NET 8 and focuses exclusively on the backend, with new content on REST APIs, the REPR pattern, and building modular monoliths. You’ll start by covering foundational concepts like REST, the SOLID principles, Minimal APIs, dependency injection in .NET, and other ASP.NET Core 8 mechanisms. Then, you’ll learn to develop components using design patterns, including many from the GoF. Finally, you’ll explore organizing your application code with patterns that vary from layers to feature-oriented vertical slice designs, covering CQS and a deep dive into microservices along the way. A brand-new e-commerce project at the end of the book will tie it all together. This how-to guide will teach you how to assemble your own APIs from building blocks, to suit whatever real-world requirements you may have.

Summary

We delved into the Request-EndPoint-Response (REPR) design pattern and learned that REPR follows the most foundational pattern of the web. The client sends a request to an endpoint, which processes it and returns a response. The pattern focuses on designing the backend code around the endpoint, making it faster to develop, easier to find your way around the project, and more focused on features than MVC and layers.

We also took a CQS approach to the requests, making them queries or commands, and depicting all that can happen in a program: read or write states.

We explored ways to organize code around such a pattern, from implementing trivial to more complex features. We built a technology stack to create an e-commerce web application that leverages the REPR pattern and a feature-oriented design. We learned how to leverage middleware to handle exceptions globally and how the ExceptionMapper library provides us with this capability. We also used gray-box testing to cover...
