vue3.0 vite引入SVG iconfont

1.安装

cnpm i vite-plugin-svg-icons -D

2.配置 vite.config.ts

import viteSvgIcons from 'vite-plugin-svg-icons';
import path from 'path';

export default () => {
  return {
    plugins: [
      viteSvgIcons({
        // 指定需要缓存的图标文件夹
        iconDirs: [path.resolve(process.cwd(), 'src/icons')],
        // 指定symbolId格式
        symbolId: 'icon-[dir]-[name]',
      }),
    ],
  };
};

3.在 src/main.ts 内引入注册脚本

import 'virtual:svg-icons-register';

4.创建组件

//src/components/SvgIcon/index.vue

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

<script lang="ts">
  import { defineComponent, computed } from 'vue'

  export default defineComponent({
    name: 'SvgIcon',
    props: {
      prefix: {
        type: String,
        default: 'icon'
      },
      name: {
        type: String,
        required: true
      },
      color: {
        type: String,
        default: '#333'
      }
    },
    setup(props) {
      const symbolId = computed(() => `#${props.prefix}-${props.name}`)
      return { symbolId }
    }
  })
</script>
<style lang="less" scoped>
  .svg-icon-spin {
    width: 1em;
    height: 1em;
    fill: currentColor;
    vertical-align: middle;
  }
</style>

5.icons 目录结构

# src/icons

- icon1.svg
- icon2.svg
- icon3.svg
- dir/icon1.svg

6.使用

<template>
  <div>
    <SvgIcon name="icon1"></SvgIcon>
    <SvgIcon name="icon2"></SvgIcon>
    <SvgIcon name="icon3"></SvgIcon>
    <SvgIcon name="dir-icon1"></SvgIcon>
  </div>
</template>

<script>
  import { defineComponent, computed } from 'vue';
  import SvgIcon from './components/SvgIcon.vue';
  export default defineComponent({
    name: 'App',
    components: { SvgIcon },
  });
</script>
