const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const autoprefixer = require('autoprefixer');

const path = require('path');

const htmlWebpackPluginConfig = new HtmlWebpackPlugin({
  template: __dirname + '/src/public/index.html',
  inject: 'body',
  scriptLoading: 'defer',
});

const miniCssExtractConfig = new MiniCssExtractPlugin({
  filename: '[name].[hash].css',
  chunkFilename: '[id].[hash].css',
});

module.exports = {
  entry: __dirname + '/src/index.js',
  output: {
    // path: __dirname + '/dist',
    path: __dirname,
    filename: '[name].[hash].js',

For myself, I solve this problem by adding a line to the config: auto: /\.module\.\w+$/i,.
This means that css modules will only work for those css files that have ".module" in their name.
For example: app.module.scss

{
            loader: 'css-loader',
            options: {
              modules: {
                exportGlobals: true,
                localIdentName: '[local]--[hash:base64:5]',
                auto: /\.module\.\w+$/i,
              },
            },
          },
