vite4+react+antd需要注意的地方，本地svg单独引用

一、less、css、sass不生效问题。

方案1

less或者css，sass需要用到模块化的话，后缀名全部要加上《module》如*.module.less。否则不会生效

js复制代码import styles from './index.module.less';
<div className={styles.oneApp}>生效。

vite.config.ts添加css和less

css: {
    //* css模块化
    modules: {
            // css模块化 文件以.module.[css|less|scss]结尾 
        generateScopedName:'[name]__[local]___[hash:base64:5]',hashPrefix:'prefix',
	 },
	// 预处理器配置项
			preprocessorOptions: {
				less: {
					math: 'always',
					javascriptEnabled: true,
				},
			},
		},

方案2

npm install vite-plugin-style-modules

jsx复制代码import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import viteCssModule from 'vite-plugin-style-modules';
// 支持ESM和CommonJS两种方式引入
// const viteCssModule = require('vite-plugin-style-modules')

export default defineConfig({
  plugins: [react(), viteCssModule()],
});

二、本地动态svg。

vite-plugin-svgr

安装依赖 "vite-plugin-svgr": "^3.2.0", vite.config.ts添加svgr()

js复制代码import svgr from 'vite-plugin-svgr';
plugins: [react(), svgr()]

tsconfig.json的compilerOptions加入属性

js复制代码"compilerOptions": {
		"types": ["vite-plugin-svgr/client"],

渲染组件

jsx复制代码// 动态渲染图标
const IconRender: React.FC<{
	icon: string;
	className?: string;
}> = ({ icon, ...restIconProps }) => {
	if (typeof icon !== 'string') return null; // 图标名称类型必定为string
	const allIcons: any = import.meta.glob('/plugins/icons/svg/*/*.svg', { eager: true });
	const Icon = allIcons[`/plugins/icons/svg/filled/${icon}.svg`].ReactComponent || null;
	return <Icon {...restIconProps} />;
};

jsx复制代码<IconRender
icon={item.icon}
className={cn(styles.oneItemIcon, styles.menuIcon)}/>

其中，menuIcon的样式，注意：menuIcon里面一定要有fill:currentColor，颜色才会生效

less复制代码.oneItemIcon {
			font-size: 16px;
			vertical-align: top;
		}
		.menuIcon {
			display: inline-block;
			fill: currentColor;
			color: inherit;
			font-style: normal;
			line-height: 0;
			text-align: center;
			text-transform: none;
			vertical-align: -0.125em;
			text-rendering: optimizeLegibility;
			-webkit-font-smoothing: antialiased;
			width: 1em;
			height: 1em;
		}

SVG动态组件引用,vite每个本地svg可单独引用。

之前umi系统里面的用法：

javascript复制代码import {
  CaretDownOutlined,
  LeftOutlined,
  QaWenjianquanxiankongzhiOutlined,
  QaXiazairizhiOutlined
} from "@@/plugin-icons";

按照上面的动态svg的步骤完成后。执行如下步骤 1、在更目录建一个plugins文件夹，里面再建个icons文件夹，如下

createIndex.js是脚本文件，用来执行js脚本。 index.source.tsx就是导出svg的js原参考代码。 index.tsx是通过执行脚本createIndex.js生成的文件。 createIndex.js如下

ini复制代码// 引入核心模块(fs)
import fs from 'fs';
import path from 'path';
// API
let fileContent = `//本文件采用命令生成，不要手动修改，具体查看createIndex.js,执行命令：yarn buildLocalIcons
const allIcons: any = import.meta.glob('/plugins/icons/svg/*/*.svg', { eager: true });
// 匹配到的首字母或斜杠字母转为大写
const toUpperCase = (match: string) => match?.replace('-', '').toUpperCase();
const iconList: any = {};
Object.keys(allIcons).forEach((key) => {
	const arr = key.split('/');
	const name = arr[arr.length - 1].split('.')[0];
	// 用正则匹配转化单词,转化后加上风格
	const suffix = key.indexOf('/filled/') > -1 ? 'Filled' : 'Outlined';
	const iconKey = name.replace(/(^[a-z]|\-[a-z])/g, (match) => toUpperCase(match)) + suffix;
	const Icon = allIcons[key].ReactComponent || null;
	iconList[iconKey] = Icon;
});
export default iconList;
`
// 匹配到的首字母或斜杠字母转为大写
const toUpperCase = (match) => match?.replace('-', '').toUpperCase();
function walkSync (currentDirPath, callback) {
	fs.readdirSync(currentDirPath, { withFileTypes: true }).forEach(function (dirent) {
		var filePath = path.join(currentDirPath, dirent.name);
		if (dirent.isFile()) {
			callback(filePath, dirent);
		} else if (dirent.isDirectory()) {
			walkSync(filePath, callback);
		}
	});
}

const files = []
walkSync('./plugins/icons/svg/', function (filePath, stat) {
	files.push(filePath)
});
const iconNames = []
files.forEach((key) => {
	if (key.indexOf('.svg') > -1) {
		const arr = key.split('/');
		const name = arr[arr.length - 1].split('.')[0];
		// 用正则匹配转化单词,转化后加上风格
		const suffix = key.indexOf('/filled/') > -1 ? 'Filled' : 'Outlined';
		const iconKey = name.replace(/(^[a-z]|\-[a-z])/g, (match) => toUpperCase(match)) + suffix;
		iconNames.push(iconKey)
	}
})
iconNames.forEach((key) => {
	fileContent += `export const ${key} = iconList['${key}'];\n`
})

fs.writeFile('./plugins/icons/index.tsx', fileContent, (error) => {
	// 创建失败
	if (error) {
		console.log('\x1B[31m%s\x1B[0m', `创建失败：${error}`);
	}
	// 创建成功
	console.log('\x1B[36m%s\x1B[0m', '创建本地Icons成功！');
});

index.tsx如下，index.source.tsx的内和下面一样，就是少了export default iconList;后面的代码。

ini复制代码//本文件采用命令生成，不要手动修改，具体查看createIndex.js,执行命令：yarn buildLocalIcons
const allIcons: any = import.meta.glob('/plugins/icons/svg/*/*.svg', { eager: true });
// 匹配到的首字母或斜杠字母转为大写
const toUpperCase = (match: string) => match?.replace('-', '').toUpperCase();
const iconList: any = {};
Object.keys(allIcons).forEach((key) => {
	const arr = key.split('/');
	const name = arr[arr.length - 1].split('.')[0];
	// 用正则匹配转化单词,转化后加上风格
	const suffix = key.indexOf('/filled/') > -1 ? 'Filled' : 'Outlined';
	const iconKey = name.replace(/(^[a-z]|-[a-z])/g, (match) => toUpperCase(match)) + suffix;
	const Icon = allIcons[key].ReactComponent || null;
	iconList[iconKey] = Icon;

执行项目前先把本地的icon生成下，svg新增变动都要重新执行命令

json复制代码"dev": " yarn buildLocalIcons && vite --force --mode development",
"build": "yarn buildLocalIcons && vite build --mode production",
"buildLocalIcons": "node ./plugins/icons/createIndex.js",

less相关，rgb(0 0 0 / 25%)问题

vite.config.ts

css复制代码css:{
    devSourcemap: true,
    preprocessorOptions:{
        less: {
            // math: 'always',//如果开启always会把less里面的rgb(0 0 0 / 25%)变黑色
            javascriptEnabled: true,
        },
    }
}
    ```
