# Style Build Helper This is a partial [Webpack](https://webpack.js.org/) config for building WooCommerce component styles using base styles from Gutenberg. It is used to replace the [`bin/packages/build.js`](https://github.com/woocommerce/woocommerce-admin/blob/6859249/bin/packages/build.js) script. ## Usage Create a `webpack.config.js` in your package root that defines the `entry` and `output`, making use of the `rules` and `plugins` from `@woocommerce/internal-style-build`. ***Note:*** The `entry` should be named `'build-style'` so the CSS will get picked up by the main `client/` application's `CopyWebpackPlugin` config. ```js // packages//webpack.config.js import { webpackConfig } from '@woocommerce/internal-style-build'; module.exports = { mode: process.env.NODE_ENV || 'development', entry: { 'build-style': __dirname + '/src/style.scss', }, output: { path: __dirname, }, module: { rules: webpackConfig.rules, }, plugins: webpackConfig.plugins, }; ```
