Vue3 Tutorial

Vue.js (pronounced /vjuː/, similar to view) is a progressive framework for building user interfaces.

Vue focuses only on the view layer, adopting a bottom-up incremental development design.

Vue's goal is to implement reactive data binding and composed view components with the simplest possible API.

Vue is very easy to learn. This tutorial is tested based on Vue3 and above versions.

Progressive Framework

A progressive framework is a framework that allows developers to gradually introduce and use its features based on project requirements, without needing to use all the framework's features at once.

Common progressive frameworks include: Vue, React, Angular, etc.

Advantages of progressive frameworks:

  • Easy to get started: Developers can start with basic features and learn and use them gradually.
  • Flexibility: Introduce framework features on demand, compatible with existing code.
  • Lower learning curve: Learn in stages, gradually mastering advanced features.
  • Improved efficiency: Quickly build prototypes and gradually expand features.
  • Compatibility with other technologies: Lightweight design, can coexist with existing technologies.
  • Reduced technical debt: Avoid large-scale refactoring at the beginning.

Knowledge you need to know before reading this tutorial:

  • HTML
  • CSS
  • JavaScript

This tutorial mainly introduces the use of Vue3.x versions.

Features and Advantages of Vue.js

  • Reactive data binding: Vue.js provides a powerful reactive data binding system, ensuring that data changes are automatically reflected in the view layer, reducing the need for developers to manually manipulate the DOM.

  • Component-based: Vue.js advocates decomposing applications into small, reusable components, enhancing code organization, maintainability, and reusability.

  • Flexibility and progressiveness: Vue.js is a progressive framework that allows its features (such as Vue Router and Vuex) to be introduced on demand, adapting to projects of different scales.

  • Concise template syntax: Vue.js provides an intuitive, easy-to-learn template syntax that allows the direct use of directives in HTML (such asv-if、v-foretc.) for data binding and DOM manipulation.

  • Virtual DOM: Vue.js uses a virtual DOM to improve performance, reducing actual DOM operations by comparing old and new virtual DOMs, thereby improving rendering efficiency.

  • Two-way data binding: Similar to Angular, Vue.js provides two-way data binding (v-model), which synchronizes form inputs with the data model, simplifying the management of data flow.

  • Lightweight and efficient: Compared to other frameworks (such as Angular or React), Vue.js is more lightweight, with a small and well-optimized core library, suitable for fast loading.

  • Powerful toolchain support: Vue.js provides complete development toolchain support, including Vue CLI, Vue Devtools, etc., helping developers efficiently build, debug, and optimize applications.

  • Easy integration: Because Vue.js can be introduced gradually, it is easy to integrate with existing projects or other frameworks, suitable for different scenarios from small projects to large applications.

  • Rich ecosystem: Vue.js has an active community and a rich ecosystem, including official libraries such as Vue Router and Vuex, as well as a large number of third-party plugins and components.
