Learn everything there is to know about the new secure runtime for JavaScript: Deno. A proposed replacement for Node.js envisioned and created by the same developer who wrote the first version of Node, Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. This book will cover everything from its inception to the currently available version.You'll see how to take advantage of the security layer in order to avoid unwanted security holes, and how to use TypeScript to develop your applications without having to manually set up a build process. You'll also learn how to create and use modules without having to depend on a package manager, and much more. Armed with these newly learned concepts, by the time you finish this book, you'll be ready to build and test your own Deno applications.
Whether you're a brand new developer to the back end with a JavaScript background or a seasoned Node.js developer looking to understand this competing technology, Introducing Deno will put you on the right path.
What You'll Learn
- Learn why Deno was created and why it is different from Node
- Build real applications using Deno and related technologies
- Create backend applications with Typescript
- Resolve how to live without npm and package.json
- Set permissions and default behavior
Who This Book Is For
Anyone with knowledge of back-end development looking to learn a new way of doing things and those with a basic understanding of JavaScript and Node.js core concepts.

Autoren-Porträt von Fernando Doglio
Fernando Doglio has been a part of the Software Development industry for the past 16 years. He's worked on countless web projects, which include (amongst other things) APIs, Web Services, SPA, Node.js applications, PHP, Ruby, and a lot of JavaScript/HTML/CSS. He was there when SOAP hit the web and it was all the rage and he was also there when XML was the magic X on AJAX. He's worked with Node.js for several years now and he's written several books and countless articles about it, covering everything from the art of designing REST APIs with it to understanding the best design patterns and how they can be implemented with it. Now, working as a Technical Manager, he's an eager evangelist of using JavaScript for backend development given how flexible and powerful this language is. You can find him on Twitter @deleteman123.
