Miscellaneous utility functions for dealing with checkout functionality.

extensionCartUpdate

When executed, this will call the cart/extensions REST API endpoint. The new cart is then received into the client-side store. extensionCartUpdate returns a promise that resolves when the cart is updated which should also be used for error handling.

extensionCartUpdate Usage

// Aliased import
import { extensionCartUpdate } from '@woocommerce/blocks-checkout';

// Global import
// const { extensionCartUpdate } = wc.blocksCheckout;

extensionCartUpdate( {
	namespace: 'extension-unique-namespace',
	data: {
		key: 'value',
	},
} ).then( () => {
	// Cart has been updated.
} ).catch( ( error ) => {
	// Handle error.
} );

extensionCartUpdate Options

The following options are available:

args (object, required)

Args to pass to the Rest API endpoint. This can contain data and a namespace to trigger extension specific functionality on the server-side. You can read more about this, and the server-side implementation, in this doc.

mustContain

Ensures that a given value contains a string, or throws an error.

mustContain Usage

// Aliased import
import { mustContain } from '@woocommerce/blocks-checkout';

// Global import
// const { mustContain } = wc.blocksCheckout;

mustContain( 'This is a string containing a <price />', '<price />' ); // This will not throw an error
mustContain( 'This is a string', '<price />' ); // This will throw an error

mustContain Options

The following options are available:

value (string, required)

Value being checked. Must be a string.

requiredValue (string, required)

What value must contain. If this is not found within value, and error will be thrown.
