# Vue 3 + Typescript + Vite
#### 项目初始化 yarn or cnpm or npm 安装 【本项目为了速度一律 cnpm】
cnpm init @vitejs/app or yarn create @vitejs/app 或者快捷命令 cnpm init @vitejs/app my-vue-app --template vue-ts Node.js: - 版本最好大于 12.0.0 yarn > npm > cnpm: - 包管理工具
### 安装依赖
cnpm i
### 安装路由
cnpm i vue-router@4 -S 【--save】
### 安装 vuex
cnpm i vuex@next -S 【--save】
### 安装国际化
cnpm i vue-i18n@next -S cnpm i js-cookie -S cnpm i @types/js-cookie -D
console.log(import.meta.env.VITE_APP_BASE_URL, 'VITE_APP_BASE_URL')
console.log(process.env.NODE_ENV)
### 启动项目
cnpm run dev
### 代码规范 vscode 需要安装的相关插件 Eslint Prettier Prettier Eslint 三个即可
cnpm i eslint -D 根目录下创建 .eslintrc.js 文件 eslint 官方配置文档：https://eslint.org/docs/user-guide/configuring/configuration-files#using-configuration-files
node 环境的类型检查 cnpm i @types/node -D
cnpm i prettier -D 根目录下创建 .prettierrc.js 文件 prettier 官方配置文档：https://prettier.io/docs/en/
安装相关依赖
cnpm i @typescript-eslint/eslint-plugin -D
cnpm i @typescript-eslint/parser -D
cnpm i eslint-config-prettier -D
cnpm i eslint-plugin-prettier -D
cnpm i eslint-plugin-vue -D
cnpm i eslint-define-config -D
### git 代码提交
cnpm i husky lint-staged -D 【git 代码提交规范】 package.json 文件中配置下
cnpm i eslint-plugin-vue@latest @typescript-eslint/eslint-plugin@latest @typescript-eslint/parser@latest babel-eslint -D cnpm i eslint-config-standard eslint-friendly-formatter eslint-plugin-import eslint-plugin-standard eslint-plugin-promise -D
### 移动端适配问题
先说特别的 iPhonex 的适配 iOS11 新增特性，Webkit 的一个 CSS 函数，用于设定安全区域与边界的距离，有四个预定义的变量： safe-area-inset-left：安全区域距离左边边界距离 safe-area-inset-right：安全区域距离右边边界距离 safe-area-inset-top：安全区域距离顶部边界距离 safe-area-inset-bottom：安全区域距离底部边界距离只有设置了 viewport-fit=cover，才能使用 constant 函数
<meta name=“viewport” content=“width=device-width, viewport-fit=cover”>
body {
padding-bottom: constant(safe-area-inset-bottom);
}
fixed 元素的适配
{
padding-bottom: constant(safe-area-inset-bottom);
}
或者直接设置 body{ padding: env(safe-area-inset-left,20px) env(safe-area-inset-right,20px) env(safe-area-inset-top,20px) env(safe-area-inset-bottom,20px) }
再或者媒体查询 /_兼容 iphoneX_/ /_判断是否是 iphoneX，使用@media 媒体查询尺寸_/ @media only screen and (device-width: 375px) and (device-height: 812px) and (-webkit-device-pixel-ratio: 3) { body { top: constant(safe-area-inset-top); bottom: constant(safe-area-inset-bottom); left: constant(safe-area-inset-left); right: constant(safe-area-inset-right); } } ios11 webview 状态栏问题 【设置了固定定位页面滚动过程中两边留白】如果是纯色背景的话，可以通过给 body 设置 background 来实现填充两边的留白
scss 函数 $designWidth: 750;
@function px2vm($size){ @return #{100\*$size / $designWidth}vw } 调用 px2vm(50)
### vm vw 适配方案
cnpm i postcss-px-to-viewport -D
### 第三方 UI 库 vant
cnpm i vant@next -S 官方文档：https://vant-contrib.gitee.io/vant/v3/#/zh-CN
"browserslist": [
"defaults", // 默认 "last 2 versions",
"last 2 versions", // 兼容主流浏览器的最近两个版本 "> 1%",
"> 1%", // 兼容主流浏览器的最近两个版本 "> 1%",
"iOS 7", // 使用的浏览器需要在市场上的份额大于 1 "iOS 7",
"last 3 iOS versions" // 兼容 ios 的最新 3 个版本
]
组件样式按需加载配置
cnpm i vite-plugin-style-import -D
import styleImport from 'vite-plugin-style-import'
css:{ preprocessorOptions:{ less:{ modifyVars:{}, javascriptEnabled: true } } }, plugins:[ styleImport({ libs:[ { libraryName: 'ant-design-vue', esModule: true, resolveStyle: name => `ant-design-vue/es/${name}/style/index` } ] }) ]
### 自动添加 css 前缀插件
cnpm i autoprefixer -D
### SASS 预处理器
cnpm i node-sass sass-loader sass -D
### 生产环境生成 .gz 文件
cnpm i vite-plugin-compression -D 参考文档：https://github.com/anncwb/vite-plugin-compression
### package.json 文件配置打包命令
环境变量 VITE_ 开头
"build:dev": "vue-tsc --noEmit && vite build --mode development",
"build:test": "vue-tsc --noEmit && vite build --mode test",
"build:prod": "vue-tsc --noEmit && vite build --mode production"
### PWA 配置
cnpm i vite-plugin-pwa -D
import { VitePWA } from 'vite-plugin-pwa'
参考文档：https://github.com/antfu/vite-plugin-pwa
plugins:[
VitePWA({
manifest: {},
workbox: { skipWaiting: true, clientsClaim: true }
})
]
再来个vite.config.ts常用配置

再贴一个vuex配置
