Css modules not working in react with webpack

  Kiến thức lập trình

i’m trying to configure css modules in my react app, but I cannot figure out why it isn’t working.

enter image description hereenter image description here

const HtmlWebpackPlugin = require("html-webpack-plugin");
const path = require("path");

module.exports = {
  entry: "./index.js",
  mode: "development",
  output: {
    path: path.resolve(__dirname, "./dist"),
    filename: "index_bundle.js",
    publicPath: "/",
  },
  target: ["web", "es5"],
  devServer: {
    port: "4002",
    static: {
      directory: path.join(__dirname, "public"),
    },
    open: true,
    hot: true,
    liveReload: true,
    historyApiFallback: true,
  },
  resolve: {
    extensions: [".js", ".jsx", ".json", ".css"],
  },
  module: {
    rules: [
      {
        test: /.(js|jsx)$/,
        exclude: /node_modules/,
        use: "babel-loader",
      },
      {
        test: /.css$/,
        use: [
          "style-loader",
          {
            loader: "css-loader",
            options: {
              modules: true,
            },
          },
        ],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.join(__dirname, "public", "index.html"),
    }),
  ],
};

i’ve configured the webpack just like it is said in the documentation
