Assets in CSS Bundles in Webpack

Now let's make it so that the paths to the .png files are replaced in the CSS files during compilation:

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

Let's check how it works. Let's connect an image and a style file to the entry point:

import './images/img.png';
import './styles.css';

Let's use the path to the image in the style file:

body {
	background: url('images/img.png');
}

After assembling in CSS bundle the path to the image will be changed to the new one:

body {
	background: url('the right way from the root');
}

Set the background image in the CSS file.

Connect the image to the entry point.

Perform a build and see which file the image will be copied to and what the new path will look like in the CSS bundle.
