前言

在配置化的情况下，图标配置也显得极为重要的

---

使用vite-plugin-svg-icons动态配置

参考vite-plugin-svg-icons

安装

npm i vite-plugin-svg-icons -D

插件引入

• vite.config.ts

import { resolve } from 'path'
import { createSvgIconsPlugin } from "vite-plugin-svg-icons";
export default defineConfig(({ command, mode }) => {...return {plugins: [...createSvgIconsPlugin({// 指定需要缓存的图标文件夹// iconDirs: [resolve(pathSrc, "assets/icons")],// iconDirs: [resolve(__dirname, "src/assets/icons")],iconDirs: [resolve(process.cwd(), 'src/assets/icons')], // 指定项目内图标路径// 指定symbolId格式symbolId: "icon-[dir]-[name]",}),]}

• main.ts 项目入口引入配置

import 'virtual:svg-icons-register'

图标下载

下载方式例举几个

• 阿里图标
• Element-Plus图标

把需要使用的svg图标放置这个src/assets/icons目录

新建组件svg-icon.vue

<template><svgaria-hidden="false"class="svg-icon":style="'width:' + size + ';height:' + size"><use :xlink:href="symbolId" :fill="color" /></svg>
</template><script setup lang="ts">
import { computed } from "vue";const props = defineProps({prefix: {type: String,default: "icon",},iconClass: {type: String,required: false,default: "",},color: {type: String,default: "",},size: {type: String,default: "20px",},
});
setTimeout(() => {console.log(symbolId)
}, 5000);
const symbolId = computed(() => `#${props.prefix}-${props.iconClass}`);
</script><style scoped>
.svg-icon {display: inline-block;width: 1em;height: 1em;overflow: hidden;vertical-align: -0.15em; /* 因icon大小被设置为和字体大小一致，而span等标签的下边缘会和字体的基线对齐，故需设置一个往下的偏移比例，来纠正视觉上的未对齐效果 */outline: none;fill: currentcolor; /* 定义元素的颜色，currentColor是一个变量，这个变量的值就表示当前元素的color值，如果当前元素未设置color值，则从父元素继承 */
}
</style>

使用

<SvgIcon v-if="menu.icon" :icon-class="icon" />

import { defineComponent, ref } from "vue";
import SvgIcon from "@/components/svg-icon/index.vue";
export default defineComponent({components: {SvgIcon,},setup() {const icon = ref('document')return {icon,};},
});

使用vue组件动态配置

可以引入Element-Plus提供的icon组件，也可自定义icon组件

• IconCommunity.vue 自定义svg组件

<template><svgxmlns="http://www.w3.org/2000/svg"width="20"height="20"fill="currentColor"><pathd="M15 4a1 1 0 1 0 0 2V4zm0 11v-1a1 1 0 0 0-1 1h1zm0 4l-.707.707A1 1 0 0 0 16 19h-1zm-4-4l.707-.707A1 1 0 0 0 11 14v1zm-4.707-1.293a1 1 0 0 0-1.414 1.414l1.414-1.414zm-.707.707l-.707-.707.707.707zM9 11v-1a1 1 0 0 0-.707.293L9 11zm-4 0h1a1 1 0 0 0-1-1v1zm0 4H4a1 1 0 0 0 1.707.707L5 15zm10-9h2V4h-2v2zm2 0a1 1 0 0 1 1 1h2a3 3 0 0 0-3-3v2zm1 1v6h2V7h-2zm0 6a1 1 0 0 1-1 1v2a3 3 0 0 0 3-3h-2zm-1 1h-2v2h2v-2zm-3 1v4h2v-4h-2zm1.707 3.293l-4-4-1.414 1.414 4 4 1.414-1.414zM11 14H7v2h4v-2zm-4 0c-.276 0-.525-.111-.707-.293l-1.414 1.414C5.42 15.663 6.172 16 7 16v-2zm-.707 1.121l3.414-3.414-1.414-1.414-3.414 3.414 1.414 1.414zM9 12h4v-2H9v2zm4 0a3 3 0 0 0 3-3h-2a1 1 0 0 1-1 1v2zm3-3V3h-2v6h2zm0-6a3 3 0 0 0-3-3v2a1 1 0 0 1 1 1h2zm-3-3H3v2h10V0zM3 0a3 3 0 0 0-3 3h2a1 1 0 0 1 1-1V0zM0 3v6h2V3H0zm0 6a3 3 0 0 0 3 3v-2a1 1 0 0 1-1-1H0zm3 3h2v-2H3v2zm1-1v4h2v-4H4zm1.707 4.707l.586-.586-1.414-1.414-.586.586 1.414 1.414z"/></svg>
</template>

• index.vue

<script lang="ts" src="./index.ts" /><template><div v-for="(icon, index) in ElIcons" :key="icon + index"><el-icon><component :is="icon"></component></el-icon></div>
</template>

• index.ts

import { defineComponent, reactive } from "vue";
import IconCommunity from "@/components/icons/IconCommunity.vue";
import Menu from "@/components/menu/index.vue";
import {Document,Menu as IconMenu,Location,Setting,
} from '@element-plus/icons-vue'
export default defineComponent({components: {Document,IconMenu,Location,Setting,IconCommunity},setup() {const ElIcons = reactive(['Document', 'IconMenu', 'Location', 'Setting', 'IconCommunity'])return {ElIcons,};},
});

效果如图
