Overview of this book

Vue.js is a frontend web framework which makes it easy to do just about anything, from displaying data up to creating full-blown web apps, and has become a leading tool for web developers. This book puts Vue.js into a real-world context, guiding you through example projects that helps you build Vue.js applications from scratch. With this book, you will learn how to use Vue.js by creating three Single Page web applications. Throughout this book, we will cover the usage of Vue, for building web interfaces, Vuex, an official Vue plugin which makes caching and storing data easier, and Vue-router, a plugin for creating routes and URLs for your application. Starting with a JSON dataset, the first part of the book covers Vue objects and how to utilize each one. This will be covered by exploring different ways of displaying data from a JSON dataset. We will then move on to manipulating the data with filters and search and creating dynamic values. Next, you will see how easy it is to integrate remote data into an application by learning how to use the Dropbox API to display your Dropbox contents in an application In the final section, you will see how to build a product catalog and dynamic shopping cart using the Vue-router, giving you the building blocks of an e-commerce store.

Adding a loading screen

The last step of this chapter is to make a loading screen for our app. This will tell the user the app is loading, should the Dropbox API be running slowly (or you have a lot of data to show!).

The theory behind this loading screen is fairly basic. We will set a loading variable to true by default that then gets set to false once the data has loaded. Based on the result of this variable, we will utilize view attributes to show, and then hide, an element with the loading text or animation in and also reveal the loaded data list.

Create a new key in the data object titled isLoading. Set this variable to true by default:

      data() {
        return {
          accessToken: 'XXXX',
          structure: [],
          byteSizes: ['Bytes', 'KB', 'MB', 'GB', 'TB'],
          isLoading: true
        }
     ...
