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.

Writing end-to-end tests with Cypress

End-to-end testing is a testing practice in which we test the application flow from beginning to end. With end-to-end testing, we simulate a scenario in which a user flows through our application from some kind of an entry point to a certain outcome.

For example, an end-to-end test of a web app could include the following flow:

  • User opening the URL of the web app in their browser
  • User clicking the login link and logging in
  • User checking notifications in the web app
  • User logging out

Introducing Cypress

In this section, we'll be using Cypress for our end-to-end tests. Cypress works great with the Chrome browser. Alternatively, if you'd like to work with a Selenium-based tool...
