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.

The goal in this section is to take these values and pass them from the client to the server so the server can keep track of who's in which room, and we can set up that private communication. Currently, if user one is in the Node course and user two is in the React course, both of them are going to be able to talk to each other because this data is not used.

Getting data to the server

Now the first step in getting this data to the server is figuring out where it lives; this actually lives in the location object. We're going to use the console to just play around with it.

The location is a global object that's provided by your browser, and on it we...
