Vue使用svg图标

1. 安装相关依赖

npm i svg-sprite-loader -D
或
yarn add svg-sprite-loader -D

2. components下添加组件SvgIcon

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

3. src下添加文件夹icons

image.png

(1) svg

文件夹下存放各种svg图标

(2) index.js

import Vue from 'vue'
import SvgIcon from '@/components/SvgIcon'// svg component

Vue.component('svg-icon', SvgIcon)

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

(3) svgo.yml

plugins:
- removeAttrs:
    attrs:
      - 'fill'
      - 'fill-rule'

4. 修改main.js

import Vue from 'vue'
import App from './App.vue'
// 添加这一句，引入相关内容
import '@/icons'

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
}).$mount('#app')

5. 修改vue.config.js

const path = require('path')

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

module.exports = {
  chainWebpack (config) {
    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()
  }
}
