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.

Summary

Knowing how authentication and authorization work in minimal APIs is fundamental to developing secure applications. Using JWT bearer authentication roles and policies, we can even define complex authorization scenarios, with the ability to use both standard and custom rules.

In this chapter, we have introduced basic concepts to make a service secure, but there is much more to talk about, especially regarding ASP.NET Core Identity: an API that supports login functionality and allows managing users, passwords, profile data, roles, claims, and more. We can look further into this topic by checking out the official documentation, which is available at https://docs.microsoft.com/aspnet/core/security/authentication/identity.

In the next chapter, we will see how to add multilanguage support to our minimal APIs and how to correctly handle applications that work with different date formats, time zones, and so on.
