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.

Installing Node.js using package managers


The preferred method for installing Node.js, now, is to use the versions available in package managers, such as apt-get, or MacPorts. Package managers simplify your life by helping to maintain the current version of the software on your computer, ensuring to update dependent packages as necessary, all by typing a simple command such as apt-get update. Let's go over this first.

Installing on macOS with MacPorts

The MacPorts project (http://www.macports.org/) has for years been packaging a long list of open source software packages for macOS, and they have packaged Node.js. After you have installed MacPorts using the installer on their website, installing Node.js is pretty much this simple:

$ port search nodejs npm
