注册svg-icon组件，并引入svg

import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'// svg component
// register globally
Vue.component('svg-icon', SvgIcon)
const req = require.context('./svg', false, /\.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)
<template>
  <div v-if="isExternal" :style="styleExternalIcon" class="svg-external-icon svg-icon" v-on="$listeners" />
  <svg v-else :class="svgClass" aria-hidden="true" v-on="$listeners">
    <use :xlink:href="iconName" />
  </svg>
</template>
<script>
// doc: https://panjiachen.github.io/vue-element-admin-site/feature/component/svg-icon.html#usage
import {  isExternal } from '@/utils/validate'
export default { 
  name: 'SvgIcon',
  props: { 
    iconClass: { 
      type: String,
      required: true
    },
    className: { 
      type: String,
      default: ''
    }
  },
  computed: { 
    isExternal() { 
      return isExternal(this.iconClass)
    },
    iconName() { 
      return `#icon-${ this.iconClass}`
    },
    svgClass() { 
      if (this.className) { 
        return 'svg-icon ' + this.className
      } else { 
        return 'svg-icon'
      }
    },
    styleExternalIcon() { 
      return { 
        mask: `url(${ this.iconClass}) no-repeat 50% 50%`,
        '-webkit-mask': `url(${ this.iconClass}) no-repeat 50% 50%`
      }
    }
  }
}
</script>
<style scoped>
.svg-icon { 
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}
.svg-external-icon { 
  background-color: currentColor;
  mask-size: cover!important;
  display: inline-block;
}
</style>
