A curious JavaScript developer's practical guide to deep dive into Deno and get the most out of it for building secure web applications Key FeaturesUnderstand Deno’s essential concepts and featuresLearn how to use Deno in real-world scenariosUse Deno to develop, test, and deploy web applications and toolsBook 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. What you will learnUnderstand why you should use DenoGet to grips with tooling and the Deno ecosystemBuild Deno web applications using existing Node.js knowledge and the newest ECMA Script 6 featuresExplore the standard library and the benefits of Deno’s security modelDiscover common practices and web frameworks to build a REST API in DenoStructure a web application using common architecture practicesTest and deploy a Deno application in the cloud using DockerWho this book is for This book is for web developers who want to leverage their JavaScript and TypeScript skills in a secure, simple, and modern runtime, using Deno for web app development. Beginner-level knowledge of Node.js is recommended but not required.

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.

This book learns about developing web services based on REST architecture using Deno. Deno is the latest server runtime environment for typescript and javascript in addition to node.js which is well known to date. Yes, deno was created by Ryan Dahl who created node.js itself, will deno be the next node.js successor? Of course there are reasons behind developing a new runtime for executing typescript and javascript. Architecturally, for deno runtime javascript it still uses Google Engine V8 just like the previous node.js, but this time the deno was built using Rust and TypeScript languages, while node.js was built with C ++ and JavaScript. For asynchronous runtime and event driven deno use the open source library, Tokio. Deno support typescript built-in or out of the box in the sense can be used directly without having to first configure settings, unlike node.js. The use of javascript is also supported in addition to typescript. Deno is more secure than node.js, because by default deno cannot access files, environment access, network, without explicit declaration. What is discussed in this book? Here are the points: - Introduction and installation of deno along with visual studio code as a code editor - Use standard modules for http servers - Use of third party modules such as oak to handle requests, responses, and routing - Creating a controller and routing for CRUD functionality for the postgresql database - Using Denon to automate the compilation and deno project running - Implementation of middleware for authentication - Implement bcrypt module for password hashing - Implementation of authentication using JWT - Implementation of https server - Refactoring module - Repository pattern - Access user defined functions and stored procedures in postgresql - Bundling project - The use of PM2 as monitoring tools - The use of denoDB ORM Hopefully this book can be another alternative as a source of learning exercises, tutorials, or references for those who want to learn Deno programming.

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. This concise yet in-depth guide takes you inside scope and closures, two core concepts you need to know to become a more efficient and effective JavaScript programmer. You’ll learn how and why they work, and how an understanding of closures can be a powerful part of your development skillset. Like other books in the "You Don’t Know JS" series, Scope and Closures dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can achieve true JavaScript mastery. Learn about scope, a set of rules to help JavaScript engines locate variables in your code Go deeper into nested scope, a series of containers for variables and functions Explore function- and block-based scope, “hoisting”, and the patterns and benefits of scope-based hiding Discover how to use closures for synchronous and asynchronous tasks, including the creation of JavaScript libraries

TypeScript is a typed superset of JavaScript with the potential to solve many of the headaches for which JavaScript is famous. But TypeScript has a learning curve of its own, and understanding how to use it effectively can take time. This book guides you through 62 specific ways to improve your use of TypeScript. Author Dan Vanderkam, a principal software engineer at Sidewalk Labs, shows you how to apply these ideas, following the format popularized by Effective C++ and Effective Java (both from Addison-Wesley). You’ll advance from a beginning or intermediate user familiar with the basics to an advanced user who knows how to use the language well. Effective TypeScript is divided into eight chapters: Getting to Know TypeScript TypeScript’s Type System Type Inference Type Design Working with any Types Declarations and @types Writing and Running Your Code Migrating to TypeScript
