Book Description

Node.js is a runtime environment that revolutionizes server-side JavaScript development and combines high performance, a unified language stack, a rich ecosystem of packages, and scalability, empowering developers to build efficient, scalable, and versatile applications across a range of use cases. Node.js for Beginners takes you on a progressive learning path, starting with the basics and gradually advancing to complex topics that will give you the skills needed to leverage Node.js.

First, you'll delve into 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 explore and get hands-on with complex topics such as asynchronous programming, npm libraries, event-driven patterns for HTTP servers, RESTful API, JSON Web Tokens, and more. The final chapters will guide 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.

What you will learn

• Build solid and secure Node.js applications from scratch
• Discover how to consume and publish npm packages effectively
• Master patterns for refactoring and evolving your applications over time
• Gain a deep understanding of essential web development principles, including HTTP, RESTful API design, JWT, authentication, authorization, and error handling
• Implement robust testing strategies to enhance the quality and reliability of your applications
• Deploy your Node.js applications to production environments using Docker and PM2

Who this book is for

This book is for developers eager to learn Node.js swiftly and utilize it for web app development.
