vue中引用阿里iconfont

1.安裝svg-sprite-loader

cnpm i svg-sprite-loader -D

2.在阿里iconfont下載好icon,保存成svg格式， 放在vue項目文件下面，我這裏是icon文件夾，然後創建一個index.js文件

icons--index.js

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)

3.在components文件夾中創建一個SvgIcon文件夾以及index.vue

SvgIcon文件夾下的index.vue

<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 :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>

4.在vue.config.js中配置一下

const path = require('path')
function resolve(dir) {
    return path.join(__dirname, dir)
  }
  
// All configuration item explanations can be find in https://cli.vuejs.org/config/
module.exports = {
    configureWebpack: {
      // provide the app's title in webpack's name field, so that
      // it can be accessed in index.html to inject the correct title.
      name: '22',
      resolve: {
        alias: {
          '@': resolve('src')
        }
      }
    },
    chainWebpack(config) {
      config.plugins.delete('preload') // TODO: need test
      config.plugins.delete('prefetch') // TODO: need test
  
      // set svg-sprite-loader
      config.module
        .rule('svg')
        .exclude.add(resolve('src/icons'))
        .end()
      config.module
        .rule('icons')
        .test(/\.svg$/)
        .include.add(resolve('src/icons'))
        .end()
        .use('svg-sprite-loader')
        .loader('svg-sprite-loader')
        .options({
          symbolId: 'icon-[name]'
        })
        .end()
  
      // set preserveWhitespace
      config.module
        .rule('vue')
        .use('vue-loader')
        .loader('vue-loader')
        .tap(options => {
          options.compilerOptions.preserveWhitespace = true
          return options
        })
        .end()
  
    }
  }
