webpack not generating css file

Question

Implementing webpack asset management tutorial .but webpack is not generating css file in output path

webpack.config.js

const config = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: __dirname + '/build'
  },
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader'
        ]
      },
      {
        test: /\.(jpeg)$/,
        use: [
          {
            loader: 'file-loader',
            options: {
              name: '[path][name].[ext]'
            }
          }
        ]
      }
    ]
  }
};

index.js

  import './style.css';
  import Icon from './yo1.jpg';

  function component() {
    var element = document.createElement('div');

    element.innerHTML = 'hello webpack'
    element.classList.add('hello');

    var myIcon = new Image();
    myIcon.src = Icon;

    element.appendChild(myIcon);

    return element;
  }

  document.body.appendChild(component());

Problem

images are nicely created in build folder

but

it does not creates style.css in build folder , what wrong i am doing ?

webpack does not create separate css files. It get's bundled with the javascript and is injected into the DOM as style tags by webpack bootstrap code.

If you want to create separate css file, you can use the ExtractTextPlugin - https://github.com/webpack-contrib/extract-text-webpack-plugin

const ExtractTextPlugin = require("extract-text-webpack-plugin");

module.exports = {
  module: {
    rules: [
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: "style-loader",
          use: "css-loader"
        })
      }
    ]
  },
  plugins: [
    new ExtractTextPlugin("styles.css"),
  ]
}

ExtractTextPlugin is deprecated try https://github.com/webpack-contrib/mini-css-extract-plugin:

const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
  plugins: [
    new MiniCssExtractPlugin({
      // Options similar to the same options in webpackOptions.output
      // all options are optional
      filename: '[name].css',
      chunkFilename: '[id].css',
      ignoreOrder: false, // Enable to remove warnings about conflicting order
    }),
  ],
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: {
              // you can specify a publicPath here
              // by default it uses publicPath in webpackOptions.output
              publicPath: '../',
              hmr: process.env.NODE_ENV === 'development',
            },
          },
          'css-loader',
        ],
      },
    ],
  },
};
