Vue3中引入、封装和使用svg矢量图的实现示例

npm install vite-plugin-svg-icons -D
或
yarn add vite-plugin-svg-icons -D
或
pnpm install vite-plugin-svg-icons -D

import { createSvgIconsPlugin } from 'vite-plugin-svg-icons'
import path from 'path'
export default () => {
  return {
    plugins: [
      createSvgIconsPlugin({
        iconDirs: [path.resolve(process.cwd(), 'src/assets/icons')],
        symbolId: 'icon-[dir]-[name]',
      }),
    ],
  }
}

import 'virtual:svg-icons-register'

<template>
  <svg :style="{ width, height }">
    <use :xlink:href="prefix + name" rel="external nofollow"    :fill="color"></use>
  </svg>
</template>
 
<script setup>
defineProps({
  // 是否显示
  prefix: {
    type: String,
    default: '#icon-',
  },
  name: String,
  color: {
    type: String,
    default: '#000',
  },
  width: {
    type: String,
    default: '16px',
  },
  height: {
    type: String,
    default: '16px',
  },
 
})
</script>
 
<style lang='scss' scoped></style>

//引入项目中的全局组件
import SvgIcon from '@/components/svgIcon.vue'
 
//全局对象
const allGlobalComponents = { SvgIcon }
 
//对外暴露插件对象
export default {
  install(app) {
    //注册项目的全部组件
    Object.keys(allGlobalComponents).forEach((key) => {
      //注册为全局组件
      app.component(key, allGlobalComponents[key])
    })
  },
}

import GlobalComponents from '@/plugin'
app.use(GlobalComponents)

<svg-icon name="ticl" width="20px" height="20px"></svg-icon>
