封装公共组件中在main.js中通过插件统一注册

插件：插件 (Plugins) 是一种能为 Vue 添加全局功能的工具代码（也可以注册组件）
https://cn.vuejs.org/guide/reusability/plugins.html

全局注册组件：https://cn.vuejs.org/guide/components/registration.html

import { App } from 'vue'
import table from './src/index.vue' //引入组件

// 让这个组件可以通过use的形式使用
export default {
  install(app: App) {
    app.component('m-table', table) //插件为注册组件
  }
}

import { App } from 'vue'
// 每一个引入的都是一个插件
import chooseArea from './chooseArea' 
import chooseIcon from './chooseIcon'
import trend from './trend'
import notification from './notification'
import list from './list'
import menu from './menu'
import chooseTime from './chooseTime'
import chooseDate from './chooseDate'
import progress from './progress'
import chooseCity from './chooseCity'
import form from './form'
import modalForm from './modalForm'
import table from './table'
import calendar from './calendar'

const components = [
  chooseArea,
  chooseIcon,
  trend,
  notification,
  list,
  menu,
  chooseTime,
  chooseDate,
  chooseCity,
  progress,
  form,
  modalForm,
  table,
  calendar
]

export default {
  install(app: App) {
    // 循环中使用插件
    components.map(item => {
      app.use(item)
    })
  }
}

最后可以在main.js

import mUI from './components'

app.use(use(mUI))
