Release Notes

webpack-contrib/style-loader

### [`v2.0.0`](https://togithub.com/webpack-contrib/style-loader/blob/master/CHANGELOG.md#​200-httpsgithubcomwebpack-contribstyle-loadercomparev130v200-2020-10-09) [Compare Source](https://togithub.com/webpack-contrib/style-loader/compare/v1.3.0...v2.0.0) ##### ⚠ BREAKING CHANGES - minimum supported `Node.js` version is `10.13.0` - the `esModule` option is `true` by default, you need to change `const locals = require('./styles.css')`/`require('./styles.css')` on `import locals from './styles.css'`/`import './styles.css''` ([#​489](https://togithub.com/webpack-contrib/style-loader/issues/489)) ([727a24d](https://togithub.com/webpack-contrib/style-loader/commit/727a24d173a4d71a4100ffc2a37ab6c6684a6301)) - removed support for loaders returning `String` instead of `Array` ([#​491](https://togithub.com/webpack-contrib/style-loader/issues/491)) ([7a0ce4c](https://togithub.com/webpack-contrib/style-loader/commit/7a0ce4cfd19a2be6ad8ffe274d38618a77b22199)) ##### ⚠ NOTICE To avoid problems between `style-loader` and `mini-css-extract-plugin` because of changing the `esModule` option to `true` by default we strongly recommend upgrading `mini-css-extract-plugin` to `1.0.0` version.
