Overview of this book

The sprawling landscape of various tools in JavaScript web development is becoming overwhelming. This book will show you how Vue CLI 3 can help you take back control of the tool chain. To that end, we'll begin by configuring webpack, utilizing HMR, and using single-file .vue components. We'll also use SCSS, ECMAScript, and TypeScript. We'll unit test with Jest and perform E2E testing with Cypress. This book will show you how to configure Vue CLI as your default way of building Vue projects. You'll discover the reasons behind using webpack, babel, eslint, and other modern JavaScript toolchain technologies. You'll learn about the inner workings of each through the lens of Vue CLI 3. We'll explore the extendibility of Vue CLI with the built-in settings, and various core and third-party plugins. Vue CLI helps you work with Vue components, routers, directives, and services in the Vue ecosystem. While learning these concepts, you'll examine the evolution of JavaScript. You'll learn about use of npm, IIFEs, modules in JavaScript, Common.js modules, task runners, npm scripts, module bundlers, and webpack. You'll get familiar with the reasons why Vue CLI 3 is set up the way it is. You'll also learn to perform linting with ESLint and Prettier. Towards the end, we'll introduce you to working with styles and SCSS. Finally, we'll show you how to deploy your very own Vue project on Github Pages.

Understanding how Git works

When you work on a project, if you are not using source version control such as Git, you might think that there is only one folder for your project. For example, any Vue app that you've installed using Vue CLI 3 will end up as one separate folder with a number of subfolders inside of it.

We can simplify the tree structure of such a Vue app, and describe it like this:

aVueApp
   |- aSubfolder
   |- anotherSubfolder
   |- yetAnotherSubfolder

Note that our imaginary Vue app has one root folder called aVueApp. Inside of this root folder are three subfolders that contain the complete functionality of our Vue app.

As long as we're dealing with only a few files and folders, that is, as long as our Vue app is very small, we don't have to worry about versioning our files and folders, since there's almost nothing to be versioned. If we make an...
