How to make webpack compile all scss files into one css file?

Question

JavaScript

Good afternoon! Can you please tell me how to fix the webpack config so that it compiles all *.scss into one separate *.css file?
Now it compiles a separate blob for each sass file. I don’t understand why, I do everything as in the documentation , plus I tried various articles.
What else needs to be added to make it work? I need one css file as a result.
I would be very grateful for any help.

prod config

module.exports = merge(require('./webpack.base.config'), {
    module: {
        rules: [{
            test: /\.scss$/,
            use: [
                // fallback to style-loader in development
                process.env.NODE_ENV !== 'production' ? 'style-loader' : MiniCssExtractPlugin.loader,
                "css-loader",
                "sass-loader"
            ]
        }]
    },
    plugins: [
        new MiniCssExtractPlugin({
            // Options similar to the same options in webpackOptions.output
            // both options are optional
            filename: "[name].css",
            chunkFilename: "[id].css"
        })
    ],
});

webpack.base.config


module.exports = {
    context: resolve(__dirname, '../'),
    output: {
        filename: 'bundle.js',
        path: resolve(__dirname, '../build'),
    },
    module: {
        rules: [
            {
                test: /\.(js|jsx)$/,
                exclude: /node_modules/,
                use: {
                    loader: "babel-loader"
                }
            },
            {
                test: /\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$/,
                loader: 'url-loader',
                options: {
                    limit: 8192,
                },
            },
            {
                test: /\.html$/,
                use: 'raw-loader',
            }
        ]
    },
    plugins: [
        new HtmlWebPackPlugin({
            template: "src/index.html",
        }),
    ]
};

Import all scss into one scss, then in entry point js import this scss
