vue.js3.2.20: 使用svg(svg-sprite-loader@6.0.9)

一，安装svg-sprite-loader

liuhongdi@lhdpc:/data/vue/svgdemo$ npm install svg-sprite-loader --save-dev

二，创建访问svg的类

1,创建svgIcon目录，并在其下创建svg目录: 如图:

2,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>

 

3, svgIcon/index.js

//导入svgIcon/svg下的所有svg文件
const requireAll = requireContext => requireContext.keys().map(requireContext);
/*
 第一个参数是:'./svg' => 需要检索的目录，
 第二个参数是：false => 是否检索子目录,
 第三个参数是: /\.svg$/ => 匹配文件的正则
*/
const req = require.context("./svg", false, /\.svg$/);
requireAll(req);

 

4, svgIcon/index.vue

<template>
  <svg :class="svgClass" v-bind="$attrs" :style="{color: color}">
    <use :xlink:href="iconName"/>
  </svg>
</template>

<script setup>
import { defineProps, computed } from "vue";
const props = defineProps({
  name: {
    type: String,
    required: true
  },
  color: {
    type: String,
    default: ''
  }
})

const iconName = computed(()=>`#icon-${props.name}`);
const svgClass = computed(()=> {
  console.log(props.name, 'props.name');
  if (props.name) {
    return `svg-icon icon-${props.name}`
  }
  return 'svg-icon'
});
</script>
<style scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  fill: currentColor;
  vertical-align: middle;
}
</style>

 

5,main.js

import { createApp } from 'vue'
import App from './App.vue'

import "@/svgIcon/index"
import svgIcon from "@/svgIcon/index.vue";


createApp(App).component("svg-icon", svgIcon).mount('#app')

 

三，配置vue.config.js使支持访问svg

vue.config.js

module.exports = {
            chainWebpack: config => {
                const svgRule = config.module.rule("svg");
                svgRule.uses.clear();
                svgRule
                    .use("svg-sprite-loader")
                    .loader("svg-sprite-loader")
                    .options({
                        symbolId: "icon-[name]"
                    });
            }
}

四，测试效果:

五，查看版本

1,查看loader的版本

liuhongdi@lhdpc:/data/vue/svgdemo$ npm list svg-sprite-loader
svgdemo@0.1.0 /data/vue/svgdemo
└── svg-sprite-loader@6.0.9

2,查看vue的版本:

liuhongdi@lhdpc:/data/vue/svgdemo$ npm list vue
svgdemo@0.1.0 /data/vue/svgdemo
├─┬ @vue/cli-plugin-babel@4.5.14
│ └─┬ @vue/babel-preset-app@4.5.14
│   └── vue@3.2.20 deduped
└── vue@3.2.20
