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.

The structure of our Vue-cli-based project

In this section, we'll look at the file structure of our Vue project that we have set up using Vue-cli. Our quickstart-vue folder structure is as follows:

Let's first examine the contents of the main.js file:

import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

new Vue({
  render: h => h(App)

We begin by importing Vue from the vue folder. This vue folder is located in your node_modules folder. 

Next, we import App from App.vue

As we have already learned, new Vue creates a Vue instance, and we then pass it the options object.

Inside the options object, we are only setting the render property. As we can see, the render property's value is an arrow function:

h => h(App)

The arrow function accepts, as its parameter, the App component that we imported on line two of the main.js file.

As you can probably tell, the previous function is written in ES6. Transpiled to ES5, it would look like this:
