Overview of this book

With its huge ecosystem and wide adoption, Vue is one of the leading frameworks thanks to its ease of use when developing applications. However, it can get challenging for aspiring Vue.js developers to make sense of the ecosystem and build meaningful applications. This book will help you understand how you can leverage Vue effectively to develop impressive apps quickly using its latest version – Vue 3.0. The book takes an example-based approach to help you get to grips with the basics of Vue 3 and create a simple application by exploring features such as components and directives. You'll then enhance your app building skills by learning how to test the app with Jest and Vue Test Utils. As you advance, you'll understand how to write non-web apps with Vue 3, create cross-platform desktop apps with the Electron plugin, and build a multi-purpose mobile app with Vue and Ionic. You'll also be able to develop web apps with Vue 3 that interact well with GraphQL APIs. Finally, you'll build a chat app that performs real-time communication using Vue 3 and Laravel. By the end of this Vue.js book, you'll have developed the skills you need to build real-world apps using Vue 3 by working through a range of projects.

Chapter 7: Creating a Shopping Cart System with GraphQL

In the previous chapter, we built a travel booking system with Vue 3 and Express. This was the first project where we built from scratch our own backend that is used by the frontend. Having our own backend lets us do a lot more stuff that we can't do otherwise—for example, we can save the data that we like in the database that we created ourselves. Also, we added our own authentication system to authenticate the admin user. On the admin frontend, we protect our routes with the beforeEnter route guard, which checks for the authentication token before the admin user can log in.

In this chapter, we will take a look at the following topics:

  • Introducing the GraphQL application programming interface (API)
  • Creating a GraphQL API with Express
  • Creating the admin frontend
  • Creating the customer frontend
