+```js
+import Styles from '!style-loader!css-loader?modules!./styles.css';

+- Prefixing with `!!` will disable all configured loaders (preLoaders, loaders, postLoaders)
+
+```js
+import Styles from '!!style-loader!css-loader?modules!./styles.css';
+```
+
+- Prefixing with `-!` will disable all configured preLoaders and loaders but not postLoaders
+
+```js
+import Styles from '-!style-loader!css-loader?modules!./styles.css';
+```
