Use of svg-icon (convert svg to icon for use)

1. Install svg-sprite-loader

npm install svg-sprite-loader --save

Two, vue.config.js configuration

chainWebpack: (config) => {
    
    
   // set svg-sprite-loader
   config.module.rules.delete('svg'); // 重点:删除默认配置中处理svg
   config.module
     .rule('svg-sprite-loader')
     .test(/\.svg$/)
     .include
     .add(resolve('src/icons')) // 处理svg目录
     .end()
     .use('svg-sprite-loader')
     .loader('svg-sprite-loader')
     .options({
    
    
       symbolId: 'icon-[name]',
     });
 }

3. Create a new SvgIcon component (eg src/components/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 {
    
    
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}
</style>

4. Create a new icons folder in src, and then create a new index.js and svg folder under it (for storing svg files)

The index.js file code is as follows

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)

5. Introduced in main.js

6. Use

// 例如要显示eye.svg,写法如下。style和class都可以正常使用哦，改变svg的大小和icon用法一样，使用font-size。
<svg-icon icon-class="eye"></svg-icon>
