const ExtractTextPlugin = require("extract-text-webpack-plugin");
const postCSS = new ExtractTextPlugin('../css/styles.bundle.css');

module.exports = {
    devServer: {
        port: 8080
    },
  entry: {
    app: './assets/src/js/app.js'
  },
  output: {
    path: path.resolve(__dirname, 'assets/dist/js'),
    filename: '[name].bundle.min.js'
  },
  module: {
    rules: [
        {
            test: /\.jsx?$/,
            exclude: /(node_modules|bower_components)/,
            use: {
                loader: 'babel-loader',
                options: {
                    presets: ['es2015', 'env', 'stage-0', 'react']
                }
            }
        }, 
        {
            test: /\.css$/i,
            include: [
                path.resolve(__dirname, 'assets/src/css'),
            ],
            use: postCSS.extract({
                fallback: 'style-loader',
                use: [
                    {
                        loader: 'css-loader',
                        options: {
                            importLoaders: 1,
                            config: {
                                path: 'postcss.config.js'
                            }
                        }

                    }, 'postcss-loader',

Im having this problem too

[jegbagus]

i can fix this issue after reading documentation right here : https://webpack.js.org/configuration/dev-server/
its turn to be configuration need both contentBase & publicPath. here is configuration that work for me :

devServer:{
        contentBase: path.join(__dirname, "app"),
        publicPath: "/public/",
        compress: true,
        port: 8080
},
