main.js

import svgIcon from '@/components/SvgIcon'
Vue.component('svg-icon-full', svgIcon)
const requireAll = requireContext => requireContext.keys().map(requireContext)
const req = require.context('@/assets/icons/svg', false, /\.svg$/)  // icon位置
requireAll(req)

SvgIcon组件

<template>
  <i v-if="iconFileName.indexOf('el-icon-') === 0" :class="iconFileName" />
  <svg v-else class="svg-icon" aria-hidden="true" v-on="$listeners">
    <use :xlink:href="`#icon-${iconFileName}`" rel="external nofollow" :class="[iconColor]"/>
  </svg>
</template>

<script>
export default {
  name: 'SvgIcon',
  props: {
    iconFileName: {
      type: String,
      required: true
    },
    iconColor: {
      type: String,
      default: ''
    }
  }
}
</script>

<style scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  overflow: hidden;
  vertical-align: -0.15em;
  fill: currentColor;
}
</style>

SvgIcon调用

icon-file-name="文件名"

<svg-icon-full icon-file-name="alarm" :style="{width: '14px', height: '14px', color: '#FF4621'}"/>
