Vue脚手架
Vue脚手架可以快速生成Vue项目基础的架构。
安装3.x版本的Vue脚手架
/*
npm install -g @vue/cli@3.3
*/
基于3.3版本的脚手架命令创建Vue项目
/*
1. 命令：vue create my-project
选择Manually select features(选择特性以创建项目)
2. 勾选特性可以用空格进行勾选。
? Please pick a preset: Manually select features
? Check the features needed for your project:
◉ Babel
◯ TypeScript
◯ Progressive Web App (PWA) Support
◉ Router
◯ Vuex
◯ CSS Pre-processors
❯◉ Linter / Formatter
◯ Unit Testing
◯ E2E Testing
3. ? Use history mode for router? (Requires proper server setup for index fallback in production) (Y/n) n
是否选用历史模式的路由：n
4. ? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, Router, Linter
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config:
ESLint with error prevention only
ESLint + Airbnb config
❯ ESLint + Standard config
ESLint + Prettier
ESLint选择：ESLint + Standard config
5. ? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, Router, Linter
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: Standard
? Pick additional lint features: (Press <space> to select, <a> to toggle all, <i> to invert selection
)
❯◉ Lint on save
◯ Lint and fix on commit
何时进行ESLint语法校验：Lint on save
6. ? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, Router, Linter
? Use history mode for router? (Requires proper server setup for index fallback in production) No
? Pick a linter / formatter config: Standard
? Pick additional lint features: (Press <space> to select, <a> to toggle all, <i> to invert selection
)Lint on save
? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.?
In dedicated config files
❯ In package.json
babel，postcss等配置文件如何放置：In dedicated config files(单独使用文件进行配置)
是否保存为模板：n
使用哪个工具安装包：npm
cd 项目名
npm run dev
*/
基于UI界面创建Vue项目
/*
命令：vue ui
在自动打开的创建项目网页中配置项目信息。
*/
基于2.x的旧模板,创建Vue项目
/*
npm install -g @vue/cli-init
vue init webpack my-project
*/
分析Vue脚手架生成的项目结构
/*
node_modules:依赖包目录
public：静态资源目录
src：源码目录
src/assets:资源目录
src/components：组件目录
src/views:视图组件目录
src/App.vue:根组件
src/main.js:入口js
src/router.js:路由js
babel.config.js:babel配置文件
.eslintrc.js:
*/
Vue脚手架的自定义配置
/*
A.通过 package.json 进行配置 [不推荐使用]
因为package.json主要用来管理包的配置信息, 为了方便维护,推荐将vue脚手架相关的配置,单独定义到vue.config.js配置文件中.
"vue":{
"devServer":{
"port":"9990",
"open":true
}
}
B.通过单独的配置文件进行配置，创建vue.config.js
module.exports = {
devServer:{
port:8888,
open:true
}
}

Element-UI简介
Element-UI安装
Element-UI:一套基于2.0的桌面端组件库
官网地址：http://element-cn.eleme.io/#/zh-CN
组件库
/*
npm install element-ui -S
*/
Element-UI导入使用
/*
import ElementUI from "element-ui";
import "element-ui/lib/theme-chalk/index.css";
Vue.use(ElementUI)
*/
// 复制一段element-ui代码到App.vue上
