React的Sass配置

React提供的脚手架creact-react-app创建的工程文件不像vue那种暴露出webpack来，所以添加依赖需要拐个弯。

为了配置sass需要按以下步骤进行:

 一、安装sass-loader和node-sass依赖

npm install sass-loader node-sass --save-dev

二、打开react的webpack配置

node_modules/react-scripts/config/webpack.config.js

找到module下的rules，oneof数组中，然后找到最后一个配置，修改成如下的样子

            {
              loader: require.resolve('file-loader'),
              // Exclude `js` files to keep "css" loader working as it injects
              // its runtime that would otherwise be processed through "file" loader.
              // Also exclude `html` and `json` extensions so they get processed
              // by webpacks internal loaders.
              exclude: [/.(js|mjs|jsx|ts|tsx)$/, /.html$/, /.json$/],
              options: {
                name: 'static/media/[name].[hash:8].[ext]',
              },
            },
            // ** STOP ** Are you adding a new loader?
            // Make sure to add the new loader(s) before the "file" loader.
          {
            test:/.scss$/,
            loaders: ['style-loader', 'css-loader', 'sass-loader']
          }

    

三、这样就可以愉快地使用scss文件了
