vue-cli全局组件挂载两种方式（用require.context）

1.原生挂载方式

//加载中组件
import loadingLayer from "@/components/loadingLayer.vue"
Vue.component("loadingLayer",loadingLayer)

2.运用require.context()进行一次性遍历文件夹挂载

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import "./assets/font/iconfont.css"

// 自定义组件
const requireComponents = require.context('./views', true, /\.vue$/)
// 遍历出每个组件的路径
requireComponents.keys().forEach(fileName => {
  // 组件实例
  const reqCom = requireComponents(fileName)
  // 截取路径作为组件名
  const reqComName = reqCom.name || fileName.replace(/\.\/(.*)\.vue$/, '$1')
  // 组件挂载
  Vue.component(reqComName, reqCom.default || reqCom)
})


Vue.config.productionTip = false
new Vue({
  router,
  render: h => h(App)
}).$mount('#app')
