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 an endpoint to delete a note using the HTTP verb DELETE

To delete Note, we will implement the endpoint that meets specific requirements. Let's make a list of these requirements to gain an understanding of what the request and response should look like.

The request is expected to meet the following criteria:

  • The HTTP method will be DELETE.
  • The HTTP route will be /notes/:id.
  • The resource URL will have the id of the Note that we are trying to delete.

The response is expected to meet the following criteria:

  • Delete the Note from the database using the built-in orm-based syntax whose id is the same as the id argument that is present in the resource URL.
  • After processing the delete request, the following will occur:
    • The status code will show 204, No Content.
    • The response body will be empty.
    • The Content-Type response header will be set to application/json.

With this information, we will go ahead and define the route to delete Note...
