Vue CLI 3 Quick Start Guide

By: Ajdin Imsirovic

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.

The evolution of the JS language

Looking from the vantage point of webpack, here is the chronological list of approaches, techniques, best practices, and patterns that were added to the JS ecosystem, which led to the current state of things:

  • The script tag as the answer to adding interactivity to web pages
  • Immediately invoked function expressions as the answer to modularizing libraries and avoiding code collisions
  • The problem with IIFEs
  • Sharing third-party libraries in a team environment with NPM
  • JS task runners and NPM scripts
  • Modules in JS

Let's look at each one of these solutions in more detail.

The script tag

Initially, adding JS to your web page meant that you would need to add some script tags directly in your...
