vue 中使用svg

1.安装依赖

npm install svg-sprite-loader --save-dev

2.在src/components下新建文件夹及文件SvgIcon/index.vue

<template>
  <svg :class="svgClass" aria-hidden="true" v-on="$listeners">
    <use :xlink:href="iconName" />
  </svg>
</template>

<script>
  export default {
    name: 'SvgIcon',
    props: {
      iconClass: {
        type: String,
        required: true
      },
      className: {
        type: String,
        default: ''
      }
    },
    computed: {
      iconName() {
        return `#icon-${this.iconClass}`
      },
      svgClass() {
        if (this.className) {
          return 'svg-icon ' + this.className
        } else {
          return 'svg-icon'
        }
      }
    }
  }
</script>

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

3.在src/assets/icons下新建index.js文件， index.js文件内容如下

import Vue from 'vue'
import SvgIcon from '../../components/SvgIcon'// 引入svg 组件

// 全局注册
Vue.component('svg-icon', SvgIcon)

const req = require.context('./svg', false, /.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)

4.在src/plugins/element.js 引入src/assets/icons下index.js文件 （在把element.js引入到main.js中）

import Vue from 'vue'
import Element from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import '../assets/icons/index.js'
import axios from './axios'
Vue.use(Element)
Vue.use(axios)

5.在vue.config.js文件中配置

const path = require('path');
　　

　　function resolve(dir) {
　　　　return path.join(__dirname, dir)
　　}

chainWebpack(config) {
    config.plugins.delete('preload')
    config.plugins.delete('prefetch')

    // set svg-sprite-loader
    config.module
        .rule('svg')
        .exclude.add(resolve('src/assets/icons'))
        .end()
    config.module
        .rule('icons')
        .test(/.svg$/)
        .include.add(resolve('src/assets/icons'))
        .end()
        .use('svg-sprite-loader')
        .loader('svg-sprite-loader')
        .options({
            symbolId: 'icon-[name]'
        })
        .end()

 }

6.项目中使用

在src/assets/icons/svg下新建user.svg

<svg width="130" height="130" xmlns="http://www.w3.org/2000/svg"><path d="M63.444 64.996c20.633 0 37.359-14.308 37.359-31.953 0-17.649-16.726-31.952-37.359-31.952-20.631 0-37.36 14.303-37.358 31.952 0 17.645 16.727 31.953 37.359 31.953zM80.57 75.65H49.434c-26.652 0-48.26 18.477-48.26 41.27v2.664c0 9.316 21.608 9.325 48.26 9.325H80.57c26.649 0 48.256-.344 48.256-9.325v-2.663c0-22.794-21.605-41.271-48.256-41.271z" stroke="#979797"/></svg>
