VUE项目中引人SVG

准备工作：

  VUE  =>  ^2.5.2

  WEBPACK =>  ^3.6.0

1. 第一步  webpack.base.conf.js

配置对应的loader

      {
        test: /.(png|jpe?g|gif|svg)(?.*)?$/,
        loader: 'url-loader',
        exclude: [resolve('src/icons')],
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /.svg$/,
        loader: "svg-sprite-loader",
        include: [resolve('src/icons')],
        options: {
          symbolId: "icon-[name]"
        }
      }

2.第二步 写SvgIcon组件

业务组件下svg文件夹下

<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 lang="scss" scoped>
.svg-icon {
   1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}

</style>

3.第三步 把组件挂载到全局

icons 文件夹下的index,js 文件

import Vue from 'vue'
import SvgIcon from '@/business-components/svg/SvgIcon'// svg组件
 
// register globally
Vue.component('svg-icon', SvgIcon)
 
const req = require.context('./svg', false, /.svg$/)
const requireAll = requireContext => requireContext.keys().map(requireContext)
requireAll(req)

4.第四步 mian.js引入

import './icons';
