Vue3 Tutorial

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

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

Vue's goal is to achieve responsive data binding and composed view components through 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 refers to those frameworks that allow developers to gradually introduce and use their features according to project needs, 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 from basic features and gradually learn and use them.
  • 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, gradually expand features.
  • Compatible with other technologies: Lightweight design, can coexist with existing technologies.
  • Reduce technical debt: Avoid large-scale refactoring at the beginning.

Before reading this tutorial, you need to know:

  • 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 can introduce its features on demand (such as Vue Router and Vuex), adapting to projects of different scales.

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

  • 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), synchronizing form input with the data model, simplifying data flow management.

  • 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.

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

  • Easy to integrate: Since 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.
