Overview of this book

Vue.js is a progressive web framework for building professional user interfaces for your web applications. With Vue.js 3, the frontend framework is reinforced with architectural enhancements, new base languages, new render processes, and separated core components. The book starts with recipes for implementing Vue.js 3’s new features in your web development projects and migrating your existing Vue.js apps to the latest version. You will get up and running with TypeScript with Vue.js and find succinct solutions to common challenges and pitfalls faced in implementing components, derivatives, and animation, through to building plugins, adding state management, routing, and developing complete single-page applications (SPAs). As you advance, you'll discover recipes to help you integrate Vue.js apps with Nuxt.js in order to add server-side rendering capabilities to your SPAs. You'll then learn about the Vue.js ecosystem by exploring modern frameworks such as Quasar, Nuxt.js, Vuex, and Vuetify in your web projects. Finally, the book provides you with solutions for packaging and deploying your Vue.js apps. By the end of this Vue.js book, you'll be able to identify and solve challenges faced in building Vue.js applications and be able to adopt the Vue.js framework for frontend web projects of any scale.

In Vue 2, we always needed to have a parent node wrapping the components inside the single-file components. This was caused by the way in which the render engine of Vue 2 was constructed, requiring a root element on each node.

<p>This is two</p>
<p>children elements</p>

Now, in Vue 3, it's possible to declare any number of root elements on the single-file components without the need for special plugins using the new Fragments API, which will handle the multiple root elements. This helps to maintain a cleaner final code for the user, without the need for empty shells just for wrapping elements:

<p>This is two</p>
<p>root elements...
