CheckoutContext

Description

Manages checkout process state and operations. Handles order placement, shipping/payment methods, checkout data, and form state. Integrates with cart context for checkout flow.

Import

import { CheckoutProvider, useCheckout, useCheckoutDispatch } from '@components/frontStore/checkout/CheckoutContext';

Usage

Setup Provider

import { CheckoutProvider } from '@components/frontStore/checkout/CheckoutContext';
import { FormProvider, useForm } from 'react-hook-form';

function CheckoutPage() {
  const methods = useForm();
  const [formEnabled, setFormEnabled] = useState(true);

  return (
    <FormProvider {...methods}>
      <CheckoutProvider
        placeOrderApi="/api/placeOrder"
        checkoutSuccessUrl="/checkout/success"
        allowGuestCheckout={true}
        form={methods}
        enableForm={() => setFormEnabled(true)}
        disableForm={() => setFormEnabled(false)}
      >
        {/* Checkout components */}
      </CheckoutProvider>
    </FormProvider>
  );
}

Access Checkout State

import { useCheckout } from '@components/frontStore/checkout/CheckoutContext';

function CheckoutSummary() {
  const { loading, requiresShipment, orderPlaced, orderId } = useCheckout();

  if (orderPlaced) {
    return <div>Order {orderId} placed successfully!</div>;
  }

  return (
    <div>
      {loading && <div>Processing...</div>}
      {requiresShipment && <div>Shipping required</div>}
    </div>
  );
}

Use Checkout Actions

import { useCheckoutDispatch } from '@components/frontStore/checkout/CheckoutContext';

function CheckoutButton() {
  const { checkout } = useCheckoutDispatch();

  const handleCheckout = async () => {
    try {
      const order = await checkout();
      window.location.href = `/checkout/success/${order.uuid}`;
    } catch (error) {
      alert(error.message);
    }
  };

  return (
    <button onClick={handleCheckout}>
      Place Order
    </button>
  );
}
