Node.js Web Development - Fourth Edition

By: David Herron

Overview of this book

Node.js is a server-side JavaScript platform using an event-driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. This book gives you an excellent starting point, bringing you straight to the heart of developing web applications with Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application.You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this book you'll learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well known tools to beef up security of Express 4.16 applications.

Summary

You learned a lot in this chapter. Specifically, you saw that JavaScript has a life outside web browsers and you learned about the difference between asynchronous and blocking I/O. We then covered the attributes of Node.js and where it fits in the overall web application platform market and threaded versus asynchronous software. Lastly, we saw the advantages of fast event-driven asynchronous I/O, coupled with a language with great support for anonymous closures.

Our focus in this book is real-world considerations of developing and deploying Node.js applications. We'll cover as many aspects as we can of developing, refining, testing, and deploying Node.js applications.

Now that we've had this introduction to Node.js, we're ready to dive in and start using it. In Chapter 2, Setting up Node.js, we'll go over setting up a Node.js environment, so let's get started.
