Overview of this book

Deno is a JavaScript and TypeScript runtime with secure defaults and a great developer experience. With Deno Web Development, you'll learn all about Deno's primitives, its principles, and how you can use them to build real-world applications. The book is divided into three main sections: an introduction to Deno, building an API from scratch, and testing and deploying a Deno application. The book starts by getting you up to speed with Deno's runtime and the reason why it was developed. You'll explore some of the concepts introduced by Node, why many of them transitioned into Deno, and why new features were introduced. After understanding Deno and why it was created, you will start to experiment with Deno, exploring the toolchain and writing simple scripts and CLI applications. As you progress to the second section, you will create a simple web application and then add more features to it. This application will evolve from a simple 'hello world' API to a web application connected to the database, with users, authentication, and a JavaScript client. In the third section, the book will take you through topics such as dependency management, configuration and testing, finishing with an application deployed in a cloud environment. By the end of this web development book, you will become comfortable with using Deno to create, maintain, and deploy secure and reliable web applications.

Chapter 5: Adding Users and Migrating to Oak

At this point, we have laid the foundations for a web application with a structure that will enable us to add more functionalities as we proceed. As you might have guessed by the name of this chapter, we'll start this chapter by adding the middleware framework of our choice to the current web application, Oak.

Together with Oak, and since our application is starting to have more third-party dependencies, we'll use what we've learned in previous chapters to create a lock file and perform integrity checking when installing dependencies. This way, we can guarantee that our applications will run smoothly without dependency problems.

As we get into this chapter, we'll start understanding how to simplify our code using Oak's features. We'll make our routing logic more extendable but also more scalable. Our first solution was to use if statements together with the standard library to create a DIY routing solution...
