在vue3+vite中使用svg-sprite-loader，antdv修改菜单icon

1. 安装

npm install vite-plugin-svg-icons -D

2. 在vite.config.js的plugins中添加配置项

import { createSvgIconsPlugin } from 'vite-plugin-svg-icons';

createSvgIconsPlugin({
   iconDirs: [resolve(process.cwd(), 'src/components/svgIcon/svg')], // icon存放的目录，自定义
   symbolId: 'icon-[name]', // symbol的命名
   inject: 'body-last', // svg插入的位置
   customDomId: '__svg__icons__dom__' // svg的id
})

3. 封装svgIcon组件

组件vue文件，index.vue：

<template>
  <svg :class="svgClass" aria-hidden="true">
    <use :xlink:href="iconName" />
  </svg>
</template>

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

  const props = defineProps({
    iconClass: {
      type: String,
      required: true
    },
    className: {
      type: String,
      default: () => ''
    }
  });

  const iconName = computed(() => {
    return `#icon-${props.iconClass}`;
  });
  const svgClass = computed(() => {
    return props.className ? `svg-icon ${props.className}` : 'svg-icon';
  });
</script>

<style scoped lang="less">
  .svg-icon {
    fill: currentColor;
  }
</style>

svgIcon全局组件，index.ts

import { App } from 'vue';
import SvgIcon from '@/components/svgIcon/index.vue';

export default (app: App) => {
  app.component('SvgIcon', SvgIcon);
};

4. 全局注册组件

在main的ts中引入index.ts，用app.use注册，引入virtual:svg-icons-register

import 'virtual:svg-icons-register';
import initSvgIconfrom '@/components/svgIcon/index';

app.use(initSvgIcon);

5. 使用

<a-menu
      v-model:selectedKeys="selectMenuId"
      v-model:openKeys="openKeys"
      style="height: calc(100% - 40px)"
      mode="inline"
      @click="handleSelect"
    >
      <template v-for="item in siderMenus" :key="item.key">
        <a-menu-item v-if="!item?.children?.length" :key="item.key" :path="item.path">
          <template #icon>
            <svg-icon :icon-class="item.icon" />
          </template>
          {{ item.label }}
        </a-menu-item>
        <template v-else>
          <a-sub-menu :key="item.key" :title="item.title">
            <template #icon>
              <svg-icon :icon-class="item.icon" />
            </template>
            <a-menu-item v-for="_item in item.children" :key="_item.key" :path="_item.path">
              {{ _item.label }}
            </a-menu-item>
          </a-sub-menu>
        </template>
      </template>
    </a-menu>
