Overview of this book

Advanced Node.js Development is a practical, project-based book that provides you with all you need to progress as a Node.js developer. Node is a ubiquitous technology on the modern web, and an essential part of any web developer’s toolkit. If you're looking to create real-world Node applications, or you want to switch careers or launch a side-project to generate some extra income, then you're in the right place. This book was written around a single goal: turning you into a professional Node developer capable of developing, testing, and deploying real-world production applications. There's no better time to dive in. According to the 2018 Stack Overflow Survey, Node is in the top ten for back-end popularity and back-end salary. This book is built from the ground up around the latest version of Node.js (version 9.x.x). You'll be learning all the cutting-edge features available only in the latest software versions. This book delivers advanced skills that you need to become a professional Node developer. Along this journey you'll create your own API, you'll build a full real-time web app and create projects that apply the latest Async and Await technologies. Andrew Mead maps everything out for you in this book so that you can learn how to build powerful Node.js projects in a comprehensive, easy-to-follow package designed to get you up and running quickly.

Now, when people hear about async/await, they think that they need to forget everything they know about callbacks and promises, and that is not true. Async/await is not a third option; it is more like an enhancement for promises. We're going to go through an example using just regular old promises, things you already know how to do. Then we're going to see how async/await can enhance that code. So, to kick things off, we do need a place to put all of this. I'm going to make a brand new project on my Desktop, async-await.

We can crack that open in our editor and make sure to crack it open in your terminal as well. Now, the goal here is to just make a very simple project. We're not going to need any Node modules for this one and we are just going to need a...
