Overview of this book

A new language on the block, V comes with a promising set of features such as fast compilation and interoperability with other programming languages. This is the first book on the V programming language, packed with concise information and a walkthrough of all the features you need to know to get started with the language. The book begins by covering the fundamentals to help you learn about the basic features of V and the suite of built-in libraries available within the V ecosystem. You'll become familiar with primitive data types, declaring variables, arrays, and maps. In addition to basic programming, you'll develop a solid understanding of the building blocks of programming, including functions, structs, and modules in the V programming language. As you advance through the chapters, you'll learn how to implement concurrency in V Programming, and finally learn how to write test cases for functions. This book takes you through an end-to-end project that will guide you to build fast and maintainable RESTful microservices by leveraging the power of V and its built-in libraries. By the end of this V programming book, you'll be well-versed with the V programming language and be able to start writing your own programs and applications.

Implementing RESTful endpoints

So far, we have set up the web server using vweb in the main.v file. Also, we wrote some commonly used code in util.v. Now, we will create RESTful endpoints. The endpoints of the microservice we are going to implement will extend the App struct such that each endpoint will be a method of the App struct. Additionally, each endpoint we are going to implement returns the response of the vweb.Result type.

In the following section, we will make a list of all the endpoints we are going to implement inside a file named notes.v.

The list of RESTful endpoints in our microservice

The microservice we are going to implement will have RESTful endpoints that perform CRUD operations on a database table. The following table shows the endpoints with their corresponding HTTP verb and URL and a description of what the endpoint does along with the request payload, if applicable:
