Mastering Minimal APIs in ASP.NET Core

By: Andrea Tosato, Marco Minerva, Emanuele Bartolesi

Overview of this book

The Minimal APIs feature, introduced in .NET 6, is the answer to code complexity and rising dependencies in creating even the simplest of APIs. Minimal APIs facilitate API development using compact code syntax and help you develop web APIs quickly. This practical guide explores Minimal APIs end-to-end and helps you take advantage of its features and benefits for your ASP.NET Core projects. The chapters in this book will help you speed up your development process by writing less code and maintaining fewer files using Minimal APIs. You’ll also learn how to enable Swagger for API documentation along with CORS and handle application errors. The book even promotes ideas to structure your code in a better way using the dependency injection library in .NET. Finally, you'll learn about performance and benchmarking improvements for your apps. By the end of this book, you’ll be able to fully leverage new features in .NET 6 for API development and explore how Minimal APIs are an evolution over classical web API development in ASP.NET Core.

The simplification of code is every developer’s dream. Minimal APIs are a new feature in .NET 6 that aims to simplify code. They are used for building APIs with minimal dependencies in ASP.NET Core. Minimal APIs simplify API development through the use of more compact code syntax.

Developers using minimal APIs will be able to take advantage of this syntax on some occasions to work more quickly with less code and fewer files to maintain. Here, you will be introduced to the main new features of .NET 6 and understand the basic themes of minimal APIs, which weren’t available in .NET 5 and previous versions. You’ll see how to enable Swagger for API documentation, along with CORS, and how to handle application errors. You will learn to structure your code better with Microsoft’s new .NET framework called Dependency Injection. Finally, you will see the performance and benchmarking improvements in .NET 6 that are introduced with minimal APIs.

By the end of this book, you will be able to leverage minimal APIs and understand in what way they are related to the classic development of web APIs.
