Overview of this book

Vue.js is an open source JavaScript library for building modern, interactive web applications. With a rapidly growing community and a strong ecosystem, Vue.js makes developing complex single page applications a breeze. Its component-based approach, intuitive API, blazing fast core, and compact size make Vue.js a great solution to craft your next front-end application. From basic to advanced recipes, this book arms you with practical solutions to common tasks when building an application using Vue. We start off by exploring the fundamentals of Vue.js: its reactivity system, data-binding syntax, and component-based architecture through practical examples. After that, we delve into integrating Webpack and Babel to enhance your development workflow using single file components. Finally, we take an in-depth look at Vuex for state management and Vue Router to route in your single page applications, and integrate a variety of technologies ranging from Node.js to Electron, and Socket.io to Firebase and HorizonDB. This book will provide you with the best practices as determined by the Vue.js community.

Adding a progress bar to load pages


It's true that with an SPA the user does not have to wait for a new page to load, but he still has to wait for the data to load. In the Fetching data before switching route recipe, we had to wait a while longer after we clicked on the button to the /aboutme page. There was nothing to suggest that the data was loading, and then suddenly the page appeared. Wouldn't it be great if the user had at least some feedback that the page is loading?

Getting ready

In order to follow along, you should complete the Fetching data before switching route recipe.

This recipe will build up on top of it and I'll assume that you have all the relevant code in place already.

How to do it…

As stated earlier, I will assume that you have all the code resulting from the Fetching data before switching route recipe in place and working.

For this recipe, we will use an additional dependency--NProgress, a small utility to display a loading bar on top of the screen.
