    This plugin can extract theme color styles from all the outputed css files (such as element-ui theme colors), and make a 'theme-colors.css' file which only contains color styles. At runtime in your web page, the client part will help you to download this css file, and then replace the colors into new customized colors dynamicly.

    This is a sample:

    Implementation (Chinese):


    npm i -D webpack-theme-color-replacer

    2.Cofig for webpack

    const ThemeColorReplacer = require('webpack-theme-color-replacer')
    module.exports = {
        plugins: [
            new ThemeColorReplacer({
                fileName: 'css/theme-colors-[contenthash:8].css', // output css file name, suport [contenthash] and [hash].
                matchColors: ['#ed4040', '#4b0'], // colors array for extracting css file
                resolveCss(resultCss) { // optional. Resolve result css code as you wish.
                    return resultCss.replace(/#4b0/g, '#ed4040')
                externalCssFiles: ['./node_modules/element-ui/lib/theme-chalk/index.css'], // optional, String or string array. Set external css files (such as cdn css) to extract colors.
                changeSelector(cssSelector) { // optional, Funciton. Changing css selectors, in order to raise css priority, to resolve lazy-loading problems.
                    return cssSelector
                isJsUgly: process.env.NODE_ENV !== 'development', // optional. Set to `true` if your js is uglified. Default is set by process.env.NODE_ENV.

      var options = {
        newColors: [newColor, newColor], // new colors array, one-to-one corresponde with `matchColors`
        // changeUrl(cssUrl) {
        //   return `/${cssUrl}`; // while router is not `hash` mode, it needs absolute path
        // },
