Overview of this book

Node.js revolutionizes server-side JavaScript development and empowers developers to build efficient, scalable, and versatile applications across a range of use cases. This book is written by a Node.js core collaborator and releaser and is the only book for beginners on Node.js. It takes you on a progressive learning path that will give you the skills needed to leverage Node.js. You’ll learn Node.js fundamentals and refresh your knowledge of JavaScript before transitioning to the development of modern web applications using Node.js, Express.js, and MongoDB. You’ll get hands-on with complex topics such as asynchronous programming, npm libraries, event-driven patterns for HTTP servers, RESTful API, and JSON Web Tokens. The final chapters will walk you through the deployment process, offering insights into various strategies, including bare metal setups, virtual machines, and containerization with Docker. You’ll also be guided through the use of Process Manager 2 (PM2) for efficient process management. By the end of this Node.js book, you'll have the skills to craft, test, and deploy Node.js web applications confidently and use this powerful stack in your day-to-day projects.

Asynchronous programming in JavaScript

In JavaScript, asynchronous programming is a fundamental part of the language. It is the mechanism that allows us to perform operations in the background, without blocking the execution of the main thread. This is especially important in the browser, where the main thread is responsible for updating the user interface and responding to user actions.

Overall, asynchronous programming is a complex topic that requires a lot of practice to master, but in my opinion, it requires a change in your mindset. You will need to start thinking about how to break down your code into small chunks that can be executed in the background, and how to combine them to achieve the desired result. You’ll encounter asynchronous programming regularly while coding with JavaScript. Most operations involving interactions with external resources, such as sending and receiving data from a server or a database and reading the content from a file, will necessitate...
