vite与vue3 SvgIcon配置

1、安装依赖插件vite-plugin-svg-icons

yarn add vite-plugin-svg-icons -D

2、安装glob

不安装会提示Error: Cannot find module 'fast-glob'
yarn add fast-glob -D

3、配置vite.config.ts

3.1 iconDirs所有的 svg的文件都存放在该文件夹下

3.2 symbolId指定use标签中href格式

导出名为createSvgIconsPlugin并加大括号，不然会提示TypeError: (0 , import_vite_plugin_svg_icons.default) is not a function

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

export default defineConfig({
  plugins: [
    createSvgIconsPlugin({
      // 指定要缓存的图标文件夹
      iconDirs: [path.resolve(process.cwd(), 'src/assets/svg')],
      // 执行icon name的格式
      symbolId: 'icon-[name]',
    })
  ]
});

4、在main.ts注册脚本

import 'virtual:svg-icons-register'; // 引入svg icon注册脚本

5、通过svg实现Icon组件

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

<script>
import { computed, defineComponent } from 'vue'
export default defineComponent({
  props: {
    name: {
      type: String,
      default: ''
    },
    color: {
      type: String,
      default: ''
    },
  },
  setup(props) {
    return {
      iconName: computed(() => `#icon-${props.name}`),
      svgClass: computed(() => {
        if (props.name) {
          return `gulu-icon ${props.name}`
        }
        return 'gulu-icon'
      })
    }
  }
})
</script>

<style lang="scss" scoped>
.gulu-icon {
  width: 3em;
  height: 3em;
  position: relative;
  fill: currentColor;
  vertical-align: -2px;
}
</style>

6、引用自定义Icon组件

<template>
	 <Icon name = "alipay" />
	 <Icon name = "qq" />
	 <Icon name = "wechat" />
</template>

<script lang="ts">
import {
  Icon,
} from './components/index'

export default {
  components: {
    Icon
  }
}
</script>
