Vue3 Vite 使用 tailwindcss & element-plus & iconify

安装和使用 tailwindcss

• 官方参考地址：https://www.tailwindcss.cn/docs/guides/vue-3-vite
• 新建 Vue vite 项目，然后安装tailwindcss

# vue-3-vite 中安装
npm install -D tailwindcss@latest postcss@latest autoprefixer@latest
# 初始化，新增 tailwind.config.js and postcss.config.js
npx tailwindcss init -p

// postcss.config.js
module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {},
  },
}
// tailwind.config.js
module.exports = {
    purge: ['./index.html', './src/**/*.{vue,js,ts,jsx,tsx}'],
    darkMode: false, // or 'media' or 'class'
    theme: {
        extend: {},
    },
    variants: {
        extend: {},
    },
    plugins: [],
}

• 新增一个index.css文件

/* ./src/index.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

• 导入至 src/main.ts 中

// src/main.ts
import { createApp } from 'vue'
import App from './App.vue'
import './index.css'

createApp(App).mount('#app')

• 至此结束，可以使用了，使用时查官网，添加class里面写就行了
• 【如何解决出现Unknown at rule @applyscss(unknownAtRules)警告？】

安装和使用 element-plus

• 安装

# 安装
pnpm install element-plus

• 使用

// main.ts，完整使用
import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'

const app = createApp(App)

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

• 推荐使用方式：自动按需导入

npm install -D unplugin-vue-components unplugin-auto-import

// vite.config.ts
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
// import * as path from 'path';
import AutoImport from 'unplugin-auto-import/vite';
import Components from 'unplugin-vue-components/vite';
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers';
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [ElementPlusResolver()],
    }),
  ],
});

  ],

安装和使用 iconify

• 图标网址：https://icon-sets.iconify.design/logos/alfresco/
• 这一个也可以使用：https://www.xicons.org/#/

 pnpm add @iconify/iconify
 pnpm add vite-plugin-purge-icons @iconify/json -D

// vite.config.ts
import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
import PurgeIcons from 'vite-plugin-purge-icons';
// import * as path from 'path';
import AutoImport from 'unplugin-auto-import/vite';
import Components from 'unplugin-vue-components/vite';
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers';
// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [ElementPlusResolver()],
    }),
    PurgeIcons({
      content: ['**/*.html', '**/*.ts', '**/*.js', '**/*.vue'],
    }),
  ],
});

// main.ts
import { createPinia } from 'pinia';
import { createApp } from 'vue';
import App from './App.vue';
import router from './router';
import piniaPluginPersist from 'pinia-plugin-persist';
import './assets/styles/input.css';
import '@purge-icons/generated'; // 添加进来
const pinia = createPinia();
pinia.use(piniaPluginPersist);
const app = createApp(App);
app.use(router);
app.use(pinia);
app.mount('#app');

• 以组件的方式使用

// 定义图标组件，设置传入大小和图标名称
<script setup lang="ts">
const props = defineProps({
    icon: {
        type: String,
        default: () => 'logos:airflow'
    },
    size: {
        type: String,
        default: () => "100"
    },
})
</script>

<template>
    <span
        class="iconify"
        :data-icon="props.icon"
        :data-width="props.size"
        :data-height="props.size"
    ></span>
</template>

<style>
</style>

// 使用
<app-icon icon="logos:alfresco" size="500"></app-icon>
