vue在线动态切换主题色方案-创新互联

主要原理是利用webpack插件webpack-theme-color-replacer提取相关颜色css然后根据配置动态生成替换的css

具体实现步骤如下：

1.添加webpack插件，新建文件webpack/themePlugin.js

const ThemeColorReplacer = require('webpack-theme-color-replacer')
const forElementUI = require('webpack-theme-color-replacer/forElementUI')
const config = require('../src/config/appConfig')
module.exports = new ThemeColorReplacer({
  fileName: 'css/theme-colors.[contenthash:8].css',
  matchColors: [
    ...forElementUI.getElementUISeries(config.themeColor), //element-ui主色系列
    // '#0cdd3a', //自定义颜色
  ],
  changeSelector: forElementUI.changeSelector,
  isJsUgly: process.env.NODE_ENV !== 'development',
  // injectCss: false,
  // resolveCss(resultCss) { // optional. Resolve result css code as you wish.
  //   return resultCss + youCssCode
  // }
})
