React项目中 使用 CSS Module

yarn add react-app-rewired@2.0.2-next.0 --save-dev //这个版本比较稳定

/* package.json */
"scripts": {
   "start": "react-app-rewired start",
   "build": "react-app-rewired build",
   "test": "react-app-rewired test --env=jsdom",
}

//scss版本
yarn add --dev react-app-rewire-css-modules sass-loader sass 
//less版本
yarn add --dev react-app-rewire-less-modules

/*config-overrides.js */
const { injectBabelPlugin } = require('react-app-rewired');
const rewireCssModules = require('react-app-rewire-css-modules');

module.exports = function override(config, env) {
    //css模块化
    config = rewireCssModules(config, env);
    return config;
};
