Description

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.

A really cool read that clearly explains Deno, its principles, and use-cases while going through the important phases of building a web application. Cool that it starts with the explanation of the technology and finished with a deployed application

If you're like me, and found this book not by looking for books on Deno particularly, then you might appreciate to learn that Deno is the new project of Node.js founder, Ryan Dahl, where he and the Deno team addressed all the things they learned from developing Node.js during they years, and dedicated themselves to solve problems that Node.js - due to its widespread usage and initial design - is unlikely to solve any time soon. You can learn about these problems, motives, and how Deno solves them from this book, and much more.If you (unlike me) found this book by looking for books on Deno especially, then you're at the right place, because this book professionally presents all the most important informations on Deno and its usage that lets you get started quickly. However, this book is also more than a mere introduction. Through its pages it presents useful examples, and code to develop real-world applications with I/O, for the web, with user management, authentication, database access, configuration testing and deployment. So offers everything that one would need during their work with Deno.Who is this book for?- Professionals wanting to have a sneak-peak into Deno and the solutions it offers.- System architects designing their next project.- Developers who have some concerns about Node.js.- Developers who claim the fun back into programming while keeping high standards.Who is this book not so much for?- Developers who are not familiar with web development yet.- Those who are looking for a complete reference.- Those who like to be entertained while learning about technologies.All in all, this is a great book written with care and keen eye on both the bird's eye view and granular details of application development, presented in just the right format without wasting space and valuable time of its readers, but also focusing on the usefulness of all the information presented.I personally appreciate the professional tone and the sincere approach taken evaluating Deno and all it has to offer, while illustrating it with concrete and usable code examples.

NOTE: I am still working my way through this book - review copy provided by PacktThis book is a good start for those interested in what Deno is and what you can do with it.The book goes over the history of Deno, the architecture and tech that support Deno, how to deal with it's limitations, exploring use cases, the Toolchain, Runtime and Standard library so you get to grasp alot of what it is about and what it can do.Then you go full circle in to building an application using Deno, how to structure it (folder and app architecture) to migration (Oak) to auth, DB connection (MongoDB) then look at how to enable CORS & HTTPS and running Deno code in the browser.Lastly, the book covers testing (unit/integration) and deployment of a Deno application.I have enjoyed the book so far with plenty of the book to consume and learn from. I hope this review heps others make a decision if they want to learn a bit more about Deno and what it can do and how it can be used.

A very insightful read that clearly explains Deno and its premises. Loved how practical it is, and how you can go directly to the sections you want and learn about different parts of building a web application. Recommended!
