Webpack 4. Compile scss to separate css file

Question

Im trying to compile scss into a separate css file with no luck. As it is now the css gets into the bundle.js together with all js code. How can i separate my css into its own file?

This is how my config looks.

var path = require("path");

module.exports = {
entry: "./js/main.js",
output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bundle.js",
    publicPath: "/dist"
},
watch:true,
module: {
    rules: [
        {
            test: /\.js$/,
            use: {
                loader: "babel-loader",
                options: { presets: ["es2015"] }
            }
        },
        {
            test: /\.scss$/,
            use: [
                {
                    loader: "style-loader"
                },
                {
                    loader: "css-loader"
                },
                {
                    loader: "sass-loader"
                }
            ]
        }
    ]
}

};

Other answers gave me just headache as they were not working. I did a lot of googling and I realized you can compile scss into separate css file without using any additional plugins

webpack.config.js

const path = require('path');

module.exports = {
    entry: [
        __dirname + '/src/js/app.js',
        __dirname + '/src/scss/app.scss'
    ],
    output: {
        path: path.resolve(__dirname, 'dist'), 
        filename: 'js/app.min.js',
    },
    module: {
        rules: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                use: [],
            }, {
                test: /\.scss$/,
                exclude: /node_modules/,
                use: [
                    {
                        loader: 'file-loader',
                        options: { outputPath: 'css/', name: '[name].min.css'}
                    },
                    'sass-loader'
                ]
            }
        ]
    }
};
