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.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “In minimal APIs, we define the route patterns using the Map* methods of the WebApplication object.”

A block of code is set as follows:

app.MapGet("/hello-get", () => "[GET] Hello World!"); 
app.MapPost("/hello-post", () => "[POST] Hello World!"); 
app.MapPut("/hello-put", () => "[PUT] Hello World!"); 
app.MapDelete("/hello-delete", () => "[DELETE] Hello World!");

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

if (app.Environment.IsDevelopment()) 

Any command-line input or output is written as follows:

dotnet new webapi -minimal -o Chapter01

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Open Visual Studio 2022 and from the main screen, click on Create a new project.”
