Is there a way to generate a single JS file using Webpack instead of main.bundle.css and main.bundle.js?

Currently, my yarn build script generates 2 files, main.[hash].js and main.[hash].css. Is there any way that I can bundle even my css file to the main.[hash].js so that I only have one js file?

Here are my config files:

webpack.common.js

const webpack = require('webpack');

module.exports = {
    entry: {
        main: './src/index.js',
        vendor: './src/vendor.js',
    },
    module: {
        rules: [
            {
                test: /\.html$/,
                use: ['html-loader'],
            },
            {
                test: /\.(svg|png|jpg|gif)$/,
                use: {
                    loader: 'file-loader',
                    options: {
                        name: '[name].[hash].[ext]',
                        outputPath: 'imgs',
                    },
                },
            },
            {
                enforce: 'pre',
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'eslint-loader',
                options: {
                    cache: true,
                    emitWarning: true,
                    failOnError: true,
                },
            },
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: 'babel-loader',
            },
        ],
    },
    plugins: [
        new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery',
            'window.$': 'jquery',
            'window.jQuery': 'jquery',
        }),
    ],
};

webpack.dev.js

const path = require('path');
const merge = require('webpack-merge');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const common = require('./webpack.common');

module.exports = merge(common, {
    mode: 'development',
    output: {
        filename: '[name].bundle.js',
        path: path.resolve(__dirname, 'dist'),
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/template.html',
        }),
    ],
    module: {
        rules: [
            {
                test: /\.scss$/,
                use: ['style-loader', 'css-loader', 'sass-loader'],
            },
        ],
    },
});

webpack.prod.js

const path = require('path');
const merge = require('webpack-merge');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const OptimizeCssAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const TerserPlugin = require('terser-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const common = require('./webpack.common');

module.exports = merge(common, {
  mode: 'production',
  output: {
    filename: '[name].[contentHash].bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  optimization: {
    minimizer: [
      new OptimizeCssAssetsPlugin(),
      new TerserPlugin(),
      new HtmlWebpackPlugin({
        template: './src/template.html',
        minify: {
          removeAttributeQuotes: true,
          collapseWhitespace: true,
          removeComments: true,
        },
      }),
    ],
  },
  plugins: [
    new MiniCssExtractPlugin({filename: '[name].[contentHash].css'}),
    new CleanWebpackPlugin(),
  ],
  module: {
    rules: [
      {
        test: /\.scss$/,
        use: [
          MiniCssExtractPlugin.loader, // 3. Extract css into files
          'css-loader', // 2. Turns css into commonjs
          'sass-loader', // 1. Turns sass into css
        ],
      },
    ],
  },
});

I have also tried adding some plugins to achieve this but had not had any luck so far. If there is a plugin or some other way that you have, please help me with it.
