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.

In this chapter, we have seen several logging aspects of the implementation of minimal APIs.

We started to appreciate the ASP.NET churned logging framework, and we understood how to configure and customize it. We focused on how to define a message template and how to avoid errors with the source generator.

We saw how to use the new provider to serialize logs with the JSON format and create a custom provider. These elements turned out to be very important for mastering the logging tool and customizing it to your liking.

Not only was the application log mentioned but also the infrastructure log, which together with Application Insights becomes a key element to monitoring your application. Finally, we understood that there are ready-made tools, such as Serilog, that help us to have ready-to-use functionalities with a few steps thanks to some packages installed by NuGet.

In the next chapter, we will present the mechanisms for validating an input object to the API...
