ant-design-vue切换主题+换肤+自定义换肤+less动态换肤

换肤核心思路：

用lessjs动态改变皮肤变量
window.less.modifyVars(
{
    "primary-color": "red",
})

ant换肤的思路：

用vue文件流，读取ant的样式，然后写到一个新的less文件中，然后再把自己的less加到最终的less文件，然后引用这个大文件就行了

安装依赖

npm i antd-theme-generator --save

main.js 引用ant的less样式

//引入Antd
import Antd from 'ant-design-vue';
import "ant-design-vue/dist/antd.less";

 换肤的核心代码结构

 theme.js

const fs = require("fs");
const path = require('path');


const { generateTheme } = require('antd-theme-generator');
const options = {};
//生成的theme.less文件的位置
const outputFilePath = path.join(__dirname, '../../../static/theme.less');
//自定义样式
const cusCssFilePath = path.join(__dirname, '../cus-theme.less');

generateTheme({
  //node_modules中antd的路径
  antDir: path.join(__dirname, '../../../node_modules/ant-design-vue'), 
  //styles对应的目录路径,需要和下面的variables.less在一个文件夹
  stylesDir: path.join(__dirname, '../'), 
  //less变量的入口文件，variables.less里面定义的变量，必须在themeVariables里面定义
  varFile: path.join(__dirname, '../variables.less'), 
  //您要动态更改的变量列表
  themeVariables: ['@primary-color', '@header-item-hover-color', '@header-back-color'], 
  outputFilePath: outputFilePath,
  customColorRegexArray: [/^color\(.*\)$/],
})
  .then(res => {
    console.log('配置主题成功');
    //自定义样式与ant主题样式合并
    //读取提取过的ant样式
    const themeCss = fs.readFileSync(outputFilePath).toString();
    //读取自定义的CSS
    const cusCss = fs.readFileSync(cusCssFilePath).toString();
    fs.writeFileSync(outputFilePath, themeCss + cusCss);
    //重新覆盖themeCss
    console.log(` 主题覆盖成功. OutputFile: ${outputFilePath}`)
  })
  .catch(res => {
    console.log('配置主题失败');
  });

variables.less

//插件默认主题变量+这些变量必须在themejs里面定义好
@primary-color: #1890ff; // 全局主色
//自定义样式
@header-item-hover-color:blue;//头部项浮动颜色
@header-back-color:#1890ff;//头部底色

cus-theme.less

//自定义的样式+用到了variables里面的变量+ant的主题样式都可以用
.ant-layout-header {
    background-color: @header-back-color;
    .header-item:hover{
        background-color: @header-item-hover-color;
    }
}

package.json里面设置启动的时候运行themejs，把所有的样式生成到static文件夹

"scripts": {
    "dev": "node src/theme/js/theme.js && webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "npm run dev",
    "build": "node src/theme/js/theme.js && node build/build.js"
  },

 然后在index页面里面注册

用代码切换

window.less.modifyVars({
    "primary-color": "red",
    "header-item-hover-color":"red",
    "header-back-color":"red"
})
.then((res) => {
    console.log("成功");
})
.catch((res) => {
    console.log("错误");
});

默认样式

 输入切换代码，可随便改

核心解决了，当前主题用localStore处理下就行了，这里就不多说了，爬坑路慢慢，参考+尝试了两三天才把这功能吃透，下面是研究的参考文章

最近看到一个适应所有组件的换肤，留着后续切换组件的时候看看

GitHub - GitOfZGT/some-loader-utils: implementation for less-loader or sass-loader. Compiles Less or sass to theme CSS.
