import Vue from 'vue'
import App from './App.vue'
import router from './router'
import upperFirst from 'lodash/upperFirst' // 没有包，请导入：npm i lodash.upperfirst  或 yarn add --dev lodash.upperfist
import camelCase from 'lodash/camelCase' // 没有包，请导入：npm i lodash.camelcase 或 yarn add --dev lodash.camelcase

// 主要代码：开始
const requireComponent = require.context(
  './components/autoload',
  false,
  /_base-[\w-]+\.vue$/
)
requireComponent.keys().forEach(fileName => {
  const componentConfig = requireComponent(fileName)
  const componentName = upperFirst(
    camelCase(fileName.replace(/^\.\/_/, '').replace(/\.\w+$/, ''))
  )

  Vue.component(componentName, componentConfig.default || componentConfig)
})
// 主要代码：结束

Vue.config.productionTip = false

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