By: Ajdin Imsirovic

Overview of this book

Vue.js is the latest trending frontend framework. Simplicity, reactivity, and ?exibility are some of the key benefits that Vue offers to developers. This book will help you learn everything you need to know to build stunning reactive web apps with Vue.js 2 quickly and easily. This book will take you through the Vue 2 framework. You will start by learning the different Vue installation options: CDN, NPM, and Vue CLI. Then we will look at the core concepts of Vue: templates and components – ways to modularize Vue code. You will learn how to utilize directives, which are Vue-specific HTML attributes with additional features. Also, you will see how Vue uses a streamlined approach to development, with reusable methods, computed properties, and watchers, and how it controls state with the help of its data option. You will learn about the concepts of reactive programming in Vue, and how to understand communication between parent and child components. We will take a look at props and slots, working with CSS, filters, and mixins. We will also look at ways to add transitions and animations to Vue apps. Then you will extend Vue by building custom directives and your own plugins. Finally, you will learn about Vuex – a Vue plugin that allows us to centralize state, and also introduce Nuxt, which is a framework that builds on top of Vue and solves some issues of single-page applications. After learning about these components, you will be ready to build your own reactive web apps with Vue.js 2.

Our app component resides inside this Vue instance.

The app component usually has a child component, like we saw in this example from Chapter 2, Basic Concepts of Vue 2

Vue.component('custom-article', {
  template: `
      Our own custom article component!
new Vue({
    el: '#app'

What we did not mention in the previous chapter is this:

  • A child component can be reused as many times as needed
  • A child component can also have its own children

An example of this is available in the following pen:

Here is the code which demonstrates these two principles:

// JS
Vue.component('custom-article', {
  template: `
