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.

Working with transition groups


While a single transition component is used to wrap around a single element, transition groups are used for animating multiple elements. They come with an additional animation hook: v-move.

In the example that follows, we'll build simple functionality where users can award a piece of content online with an applause, a concept similar to the clap feature of https://medium.com/, which works as follows: if a visitor to the website likes a piece of content, they can award it with claps, by clicking the clap button up to 50 times. hence, the claps feature works like a kind of a counter of how much a piece of content is appreciated by the website visitors.

In our implementation, we will combine the features we have already covered. The difference is, instead of a transition, we will use the transition-group component. This is the HTML code:

<!-- HTML -->
<div id="app">
    <div class="tale">
        <transition-group>
          <button
