Components and utilities making it possible to integrate with the WooCommerce Mini-Cart, Cart and Checkout Blocks.

## Installation

This package is available as an external when the [WooCommerce Blocks Feature Plugin](https://wordpress.org/plugins/woo-gutenberg-products-block/) is installed and activated.

## Usage

Package components can be accessed via the `wc` global:

```js
const { ... } = wc.blocksCheckout;
```

### Aliased imports

Alternatively, you can map this to externals (or aliases) using the [WooCommerce Dependency Extraction Webpack Plugin](https://github.com/woocommerce/woocommerce-admin/tree/main/packages/dependency-extraction-webpack-plugin). Just add the above Webpack plugin to your package.json:

```bash
npm install @woocommerce/dependency-extraction-webpack-plugin --save-dev
```

Now, you can include this plugin in your Webpack configuration:

```js
// webpack.config.js
const WooCommerceDependencyExtractionWebpackPlugin = require( '@woocommerce/dependency-extraction-webpack-plugin' );

module.exports = {
	// …snip
	plugins: [ new WooCommerceDependencyExtractionWebpackPlugin() ],
};
```
