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.

Leveraging the logging framework

The logging framework, as mentioned at the beginning of the chapter, already has by design a series of providers that do not require adding any additional packages. Now, let us explore how to work with these providers and how to build custom ones. We will analyze only the Console log provider because it has all the sufficient elements to replicate the same reasoning on other log providers.

Console log

The Console log provider is the most used one because, during the development, it gives us a lot of information and collects all the application errors.

Since .NET 6, this provider has been joined by the AddJsonConsole provider, which, besides tracing the errors like the console, serializes them in a JSON object readable by the human eye.

In the following example, we show how to configure the JsonConsole provider and also add indentation when writing the JSON payload:

builder.Logging.AddJsonConsole(options =>
