+Type: `Boolean`

+
+By default, `css-loader` generates JS modules that use the CommonJS modules syntax.
+There are some cases in which using ES modules is beneficial, like in the case of [module concatenation](https://webpack.js.org/plugins/module-concatenation-plugin/) and [tree shaking](https://webpack.js.org/guides/tree-shaking/).
+
+You can enable a ES module syntax using:
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  module: {
+    rules: [
+      {
+        test: /\.css$/i,
+        loader: 'css-loader',
+        options: {
+          esModule: true,
+        },
+      },
+    ],
+  },
+};
+```
