webpack/examples/asset-simple

This is a very simple example that shows the usage of the asset module type.

Files can be imported like other modules without file-loader.

example.js

import png from "./images/file.png";
import jpg from "./images/file.jpg";
import svg from "./images/file.svg";

const container = document.createElement("div");
Object.assign(container.style, {
	display: "flex",
	justifyContent: "center"
});
document.body.appendChild(container);

function createImageElement(title, src) {
	const div = document.createElement("div");
	div.style.textAlign = "center";

	const h2 = document.createElement("h2");
	h2.textContent = title;
	div.appendChild(h2);

	const img = document.createElement("img");
	img.setAttribute("src", src);
	img.setAttribute("width", "150");
	div.appendChild(img);

	container.appendChild(div);
}

[png, jpg, svg].forEach(src => {
	createImageElement(src.split(".").pop(), src);
});

webpack.config.js

module.exports = {
	output: {
		assetModuleFilename: "images/[hash][ext]"
	},
	module: {
		rules: [
			{
				test: /\.(png|jpg|svg)$/,
				type: "asset"
			}
		]
	},
	experiments: {
		asset: true
	}
};
