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.

Chapter 14: Building a Microservice

In this chapter, we will learn how to build a simple microservice in V using a RESTful approach. To achieve this, we will be using the built-in vweb and orm libraries. Additionally, we will leverage the power of SQLite by installing it as a third-party library. With the help of the SQLite library, we will establish a database connection and interact with the database using that connection. We will also use the JSON data format as a form of communication.

In this chapter, we will cover the following topics:

  • Introducing vweb
  • Creating a project and organizing files
  • Setting up the vweb web server
  • Setting up the utility functions and constants for the microservice
  • Implementing RESTful endpoints
  • Implementing an endpoint to create a note using HTTP verb POST
  • Implementing an endpoint to retrieve a note by id using HTTP verb GET
  • Implementing an endpoint to retrieve all notes using HTTP verb GET
  • Implementing an endpoint...
