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 mixins


Mixins are a way for us to abstract out reusable functionality in our Vue code. Made popular in the frontend world by Sass, the concept of mixins is now present in a number of modern JavaScript frameworks.

Mixins are best used when we have some functionality that we would like to reuse across a number of components. In the example that follows, we will create a very simple Vue app, which will show two Bootstrap alerts on the page. When a user clicks on either of the alerts, the browser's viewport dimensions will be logged out to the console.

For this example to work, we will need to get some plain HTML components from the Bootstrap framework. Specifically, we will use the alert component.

The official documentation on this Bootstrap component can be found at this link: https://getbootstrap.com/docs/4.1/components/alerts/.

It is important to note that Bootstrap components and Vue components are different things and should not be confused.

The app, when run, will produce this...
