Vue.js 3 Cookbook

By: Heitor Ramon Ribeiro

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.

How it works...

The createDecorator function is a factory function that extends the Vue vm (View Model), which produces an extension of the Vue component, such as a Vue mixin. A Vue mixin is a property of the Vue component that can be used to share and reuse code between components.

When we call the mixin, it takes the current component as an option of the first argument (the key if it was attached to a property), and the index of it.

We added a dynamic debugger that is only attached when debug data exists and is set to true. This debugger will log the current data and set watchers for the changes in the data, showing the logs on the console each time the data is changed.
