react实现antd线上主题动态切换功能

const path = require('path');
const { generateTheme, } = require('antd-theme-generator');

const options = {
 stylesDir: path.join(__dirname, './src/css'),
 antDir: path.join(__dirname, './node_modules/antd'),
 varFile: path.join(__dirname, './src/css/variables.less'),
 mainLessFile: path.join(__dirname, './src/css/index.less'),
 themeVariables: [ //需要动态切换的主题变量
  '@primary-color',
  '@secondary-color',
  '@text-color',
  '@text-color-secondary',
  '@heading-color',
  '@layout-body-background'
 ],
 indexFileName: 'index.html',
 outputFilePath: path.join(__dirname, './public/color.less'), //页面引入的主题变量文件
}

generateTheme(options).then(less => {
 console.log('Theme generated successfully');
})
.catch(error => {
 console.log('Error', error);
});

@import "~antd/lib/style/themes/default.less"; //引入antd的变量文件，实现变量的覆盖
@primary-color: #1DA57A;
@link-color: #1DA57A;
@btn-primary-bg:#1DA57A;

<!-- 使用自动生成的color.less，主要路径与index.html文件同级 -->
<link rel="stylesheet/less" type="text/css" href="%PUBLIC_URL%/color.less" rel="external nofollow" /> 
<script>
 window.less = {
  async: false,
  env: 'production'
 };
</script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/less.js/2.7.2/less.min.js"></script>

"scripts": {
 "start": "node color && node scripts/start.js",
 "build": "node color && node scripts/build.js",
 "test": " node color && node scripts/test.js"
},

window.less.modifyVars(
 {
  '@primary-color': '#aaa',
  '@menu-dark-item-active-bg':'#aaa',
  '@link-color': '#aaa',
  '@text-color':'#aaa',
  '@btn-primary-bg': '#aaa',
 }
)
.then(() => { 
 message.success('主题切换成功')
})
.catch(error => {
 message.error(`主题切换失败`);
 console.log(error)
});
