Create ZQFClient instance
Learn how to create a ZQFClient instance from quoteState and optionally pageState so your component can read quote data and emit events to update the quote and its related objects.
Make sure that your component has access to quoteState. If your logic depends on the current interval, also make pageState available.
You can use the zqf instance to read values from quoteState and to create events for updating the quote, products, charges, tiers, amendments, and intervals.
