npm i fast-glob@3.x -D
npm i vite-plugin-svg-icons@2.x -D

<template>
  <svg aria-hidden="true" class="svg-icon">
    <use :xlink:href="symbolId" rel="external nofollow"  :fill="color" />
  </svg>
</template>

<script setup lang="ts">
import { computed } from 'vue';

const props = defineProps({
  prefix: {type: String,default: 'icon',},
  iconClass: {type: String,required: true,},
  color: {type: String,default: ''}
})

const symbolId = computed(() => `#${props.prefix}-${props.iconClass}`);
</script>

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

</style>

import { resolve } from 'path'

export default defineConfig({

import { createApp } from 'vue'
import App from './App.vue'
import router from '@/router'
import { store, key } from '@/store'

const app = createApp(App)

import 'virtual:svg-icons-register' // 引入注册脚本
import SvgIcon from '@/components/svgIcon/index.vue' // 引入组件
app.component('svg-icon', SvgIcon)

app.use(router).use(store, key).mount('#app')

<template>
  <svg-icon icon-class="category"></svg-icon>
  <svg-icon icon-class="accountant" style="width: 10em; height: 10em;border: 1px solid #000000;"></svg-icon>
