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.

Creating a project and organizing files

We can implement a microservice by placing the entire code inside a single file. However, that does not offer readability. So, instead, we will break down the code into logically related blocks and place them within relevant files. This will give us the advantage of quickly identifying the place of logic while troubleshooting any issues in the code. Well-organized code also enhances code readability.

To begin implementing the notes_api microservice, we will create a project. Then, we will add a few files to make the code organized and readable.

Run the following command to create a new project named notes_api:

v new notes_api

Once you have run the v new notes_api command, you will be prompted to provide a description, the version number, and license information, which are optional. Then, you can hit Enter.

Rename the notes_api.v file to main.v. Add two new files within the project, namely, util.v and note.v. Our new notes_api project...
