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.

Working with Minimal APIs

In this chapter, we will try to apply some advanced development techniques available in earlier versions of .NET. We will touch on four common topics that are disjointed from each other.

We’ll cover productivity topics and best practices for frontend interfacing and configuration management.

Every developer, sooner or later, will encounter the issues that we describe in this chapter. A programmer will have to write documentation for APIs, will have to make the API talk to a JavaScript frontend, will have to handle errors and try to fix them, and will have to configure the application according to parameters.

The themes we will touch on in this chapter are as follows:

  • Exploring Swagger
  • Supporting CORS
  • Working with global API settings
  • Error handling
