Vue 2 Snippet (Visual Studio Code)

⚡ Code snippets for Vue (Only Vue 2.x, Vue Router 3.x, @vue/composition-api).

Extension's page on Visual Studio Marketplace, 📖 reading feels better.

This extension is not recommended for Vue 3.x, Please create Profiles in VS Code and install the Vue 3.x technology stack extension, such as Vue 3 Snippets.

本扩展不推荐用于 Vue 3.x 版本，请在 VS Code 创建 Profiles 安装 Vue 3.x 技术栈扩展，如：Vue 3 Snippets。

Introduction 📚

"YES, YES, VERY SMOOTH, SUPER SMOOTH".

There is no need to deliberately memorize it, you can generate code according to the Vue API partial abbreviations, and special handling required to reduce conflicts. You only need to understand the Extension design rules of this extension to release your energy.

--

来自一线、为了顺手调了又调的扩展 😎。

理解本扩展的设计之后 (Vue API 部分缩写，以及减少冲突需要特别的处理方式)，无需刻意去死记硬背，几乎没有记忆成本，释放你的小宇宙！ ヾ(´︶`*)ﾉ♬

Design 🖖

Forget the framework, Focus on the business.

--

框架，框架，有别于灵活的语言，框架就是限定了各种条条框框，让开发者在限/约定的 API 中做事情；因此，开发者在编码过程中，在框架层面输入的字符要少之有少，应当通过代码片段或 AIGC 快速创建框架相关的代码结构，将更多的精力聚焦在业务逻辑代码上；本扩展就是用于辅助生成框架侧的代码 (不用关注 Vue 框架语法，仅关注业务逻辑)。

本扩展提供了 Vue 2 技术栈的代码片段，包括 Options API 、Composition API 和 Vue Router 3.x，支持 @vue/composition-api 及 unplugin-vue2-script-setup 机制下的语法。

例如，监听一个值：

property: {
  deep: true,
  immediate: true,
  handler(newValue, oldValue) {

  },
},

Watch Property

To get the above code, you only need to understand it as: watch property deep immediate, and then enter wpdi through VS Code's Suggest Match and press Enter.

想得到上面这一段代码，只需要理解为：watch property deep immediate, 然后通过 VS Code 自带的联想功能，输入 wpdi 回车即可。

再例如，声明一个 Props 属性：

property: {
  type: Object,
  default() {
    return {};
  },
  required: true,
},

"Props"

Same as above...

想得到上面这一段代码，只需要理解为：props Object default required， 然后通过 VS Code 自带的联想功能，输入 psOdr 回车即可 (注意大小写，减少冲突)，或者通过本扩展内置的 podr 缩写前缀直接生成。

仅高频常用代码提供缩写前缀。

又例如，我们在创建 .vue 文件后，要书写基本的 SFC 元素，本扩展提供许多便捷的代码片断，具体参考 〖Single-File Components / 单文件组件〗 章节内容。

Single-File Components / 单文件组件

The sfc prefix generates Vue Single-File Components, Some examples:

--

通过 sfc 前缀触发，包含大量创建 Vue 单文件组件的代码片段，部分示例如下：

Vue 2.6 及以下版本，推荐 unplugin-vue2-script-setup；

Vue 2.7 已内置 Composition API；

因此，整个 Vue2 系列，语法形式上，将有五大类🤣。

  1. Vue2 SFC-Options API
  2. Vue2 SFC-Composition API (2.7+)
  3. Vue2 SFC-Composition API <script setup> (2.7+)
  4. Vue2 SFC-Composition API Plugin (依赖 @vue/composition-api)
  5. Vue2 SFC-Composition API Plugin <script setup> (依赖 @vue/composition-api & unplugin-vue2-script-setup)

Single-File Components

Vue Language Blocks / SFC 语法定义

The vue-script prefix generates <script> language block, which contains a variety of API style scripting language blocks.

The vue-style prefix generates a <style> language block, which contains different style preprocessing language blocks.

--

vue-script 前缀生成 <script> 语言块，包含不同风格脚本语言块；

vue-style 前缀生成 <style> 语言块，包含不同样式预处理语言块。

Why isn't there VueX? / 为什么没有 VueX

In Vue 2.x, Vuex is used, while in Vue 3.x, Pinia is adopted. There are costs associated with migrating at the project level. Reusing components at the component level couples them with the state management library. Using a state library doesn't make much sense; state sharing can be achieved entirely through Vue Dependency Injection.

--

Vue 2.x 中采用 VueX，Vue 3.x 采用 Pinia，项目级别迁移有成本，组件级别复用耦合了状态管理库，用状态库没多大意义，状态共享完全可以通过 Vue 依赖注入实现。
