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 2: Building a Vue 3 Progressive Web App

In this chapter, we will look at how to create a GitHub progressive web app (PWA) with Vue 3. As we build the project, we will examine the inner workings of a Vue app by looking at the basic building blocks in depth. We will create Vue apps with components and, as we create them, we will look at the parts that make up a component and how they work.

We will also use more advanced features such as directives, when we need to do so. Directives let us manipulate the Document Object Model (DOM) without cluttering up a component's code. They provide us with a clean way to access DOM elements and work with them in a reusable way. This helps make testing easier and helps us to modularize our code.

Vue 3 comes with many built-in directives that we will use. In the previous chapter, we saw a brief overview of these. In this chapter, we will go into more detail to see how they work. These directives provide easy-to-use abstractions to make many things easier for us and are a basic feature of Vue 3 that we can't live without.

We will use components to display the data we want, which will take in inputs via props so that we can get the proper data and display it. In each component, we will add our own methods and make use of some component lifecycle methods. To reduce repetition of code, we use mixins to abstract out commonly used features in components and incorporate them into our components.

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

  • Basic theory on components and PWAs
  • Introducing the GitHub portfolio app
  • Creating the PWA
  • Serving the PWA
