Feature

• Preloading All icons are generated when the project is running, and you only need to operate dom once.
• High performance Built-in cache, it will be regenerated only when the file is modified.

新建 SvgIcon 组件

• src/components/SvgIcon/index.vue

<!-- vue文件 index.vue -->
<template>
  <svg :class="svgClass" aria-hidden="true">
    <use :xlink:href="iconName" :fill="color" />
  </svg>
</template>

<script setup>
const props = defineProps({
  iconClass: {
    type: String,
    required: true
  },
  className: {
    type: String,
    default: ''
  },
  color: {
    type: String,
    default: ''
  },
});
const iconName = computed(() => `#icon-${props.iconClass}`)
const svgClass = computed(() => props.className ? `svg-icon ${props.className}` : 'svg-icon')
</script>

<style lang="scss" scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  position: relative;
  fill: currentColor;
}
</style>

• src/components/SvgIcon/svgicon.js

UI组件库用的是 Antd Vue

// svgicon.js
import * as components from '@ant-design/icons-vue'

export default {
  install: (app) => {
    for (const key in components) {
      const componentConfig = components[key];
      app.component(componentConfig.name, componentConfig);
    }
  },
};

main.js 全局注册

• 导入上面新建的两个文件

// main.js
// svg图标
import 'virtual:svg-icons-register'
import SvgIcon from '@/components/SvgIcon/index.vue'
import antdvueIcons from '@/components/SvgIcon/svgicon.js'

• 全局注册

// main.js
import { createApp } from 'vue'

const app = createApp(App)
app.component('svg-icon', SvgIcon)

app.use(antdvueIcons)
  .mount('#app')

组件页面使用

<template>
	<svg-icon icon-class="meeting" style="width: 40px; height: 155px;" />
</template>

<script setup>
import { defineAsyncComponent } from 'vue'

const SvgIcon = defineAsyncComponent(() => import('@/components/SvgIcon/index.vue'))
</script>
