In this chapter, we built a REST API to store information about books. Node.js handles such tasks well because it has easy-to-work native modules. We successfully covered the GET, POST, PUT, and DELETE requests that created an interface to manage a simple online library.

In the next and last chapter of this book, we will build a desktop application. We will learn how Node.js can be used not only for web projects, but for desktop programs too. By the end of the next chapter, we should have a working file browser written with Node.js.
