Bundles of styles in a layout in Webpack

Now let's make Webpack automatically include the CSS bundle into the HTML layout of the site.

Let's import two CSS files to the entry point:

import './styles1.css';
import './styles2.css';

Let's set up the assembly of these files into one common bundle. First, let's perform all the necessary imports:

import path from 'path';
import MiniCssExtractPlugin from "mini-css-extract-plugin";
import HtmlWebpackPlugin from 'html-webpack-plugin';

Now let's make the settings:

export default {
	context: path.resolve( 'src'),
	entry: './index.js',
	output: {
		filename: 'build.[contenthash].js',
		path: path.resolve('dist'),
	},
	plugins: [
		new MiniCssExtractPlugin({
			filename: 'build.[contenthash].css'
		}),
		new HtmlWebpackPlugin(),
	],
	module: {
		rules: [
			{
				test: /\.css$/i,
				use: [MiniCssExtractPlugin.loader, 'css-loader'],
			},
		],
	},
};

As a result, after the build we will have a bundle with scripts and a bundle with styles connected:

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title>Webpack App</title>
		<script defer src="build.4173b379c6d6ff439604.js"></script>
		<link href="build.97299e5ee87c9c343a4c.css" rel="stylesheet">
	</head>
	<body>
		
	</body>
</html>

Include three CSS files to the entry point. Make them gather into a common bundle. Check that this bundle is automatically included in the layout file.
