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.

The following flowchart should help you visualize the steps required to cache the current folder and subfolders:

When looking at the flowchart, you can immediately see some duplication in events required for the app. At two points the app needs to decide whether a folder exists in the cache and, if it does not, query the API to get the data and store the result. Although it appears only twice on the flowchart, this functionality is required several times, once for every folder in the current location.

We will also need to separate out our displaying logic from our querying and storing logic, as we may need to load from the API and store, without...
