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.

Querying REST endpoints using Postman

In this section, we will take a look at how to use Postman. This is free software that is used to interact with web-based APIs. You can download it from the Download Postman section at https://www.postman.com/downloads/ on the official Postman website.

Once you have downloaded the free version of Postman for your OS, launch the Postman software to send requests to the microservice we have implemented using vweb.

Next, we will learn how to perform CRUD operations on the endpoints of the microservice that we created in this chapter using Postman.

Using Postman to create a note with the POST HTTP verb

In this section, we will perform the POST operation on the create note endpoint. In the earlier sections of this chapter, we defined the behavior of the create Note endpoint, which will respond differently based on different payloads. We will evaluate them in more detail in the following sections.
