Preparing the development environment

The examples in this book will use both the web browser environment and the Node.js environment. While Node.js Version 8 and higher has support for ES6+, not all browser vendors have complete support yet for ES6+ features, and we will therefore be using Babel to transpile all of our code regardless.

This book will try its best to use the same project structure for all examples, whether they're executed on the command line in Node.js or run in the browser. Because we're attempting to standardize this project structure, not every project will use all of the features we set up in this section.

The tools you will need are:

• Your favorite code editor, such as Vim, Emacs, Sublime Text, or WebStorm
• An up-to-date web browser such as Chrome or Firefox
• Node.js Version 8 LTS or higher; this book will use version 9.4.0 for all examples
• The Yarn package manager (optional; you may use npm instead)
• Various build tools such as Babel and Browserify
