Overview

The Store Notices Store allows to register and unregister containers for notices. This is useful for displaying notices in a specific location, such as a custom block.

Usage

To utilize this store you will import the STORE_NOTICES_STORE_KEY in any module referencing it. Assuming @woocommerce/block-data is registered as an external pointing to wc.wcBlocksData you can import the key via:

import { STORE_NOTICES_STORE_KEY } from '@woocommerce/block-data';

Example

The following code snippet demonstrates how to register a container for notices.

export default function Block( attributes ) {
	const context = 'your-namespace/custom-form-step';

	dispatch( 'core/notices' ).createNotice(
		'error',
		'This is an example of an error notice.',
		{ context }
	);

	return (
		<>
			<StoreNoticesContainer context={ context } />
			{ /* Your custom block code here */ }
		</>
	);
}

💡 Internally, the StoreNoticesContainer component will dispatch the registerContainer action.

Please note that this is a simple example. In practice, you will want to trigger the createNotice action in response to a user action, such as submitting a form.
