Discount 100 Off

A sample discount adapter demonstrating a fixed-amount coupon code (10000 minor units of the order currency, such as 100 CHF). Use this as a template for implementing your own coupon systems.

Registration

Not part of any preset — register it explicitly:

import { pluginRegistry } from '@unchainedshop/core';
import { HundredOffPlugin } from '@unchainedshop/plugins/pricing/discount-100-off';

pluginRegistry.register(HundredOffPlugin);

How It Works

1. User enters coupon code 100OFF
2. Adapter validates the code
3. Returns a fixed discount of 10000 minor units to be applied by Order Discount

Coupon Code

Code	Effect
100OFF	10000 minor units off the total order (case-insensitive; 100.00 for currencies with two decimals)

Usage

Apply the discount:

mutation ApplyDiscount {
  addCartDiscount(code: "100OFF") {
    _id
    total {
      amount
      currencyCode
    }
  }
}

Remove the discount:

mutation RemoveDiscount {
  removeCartDiscount(discountId: "discount-id") {
    _id
  }
}

Configuration

The adapter targets shop.unchained.pricing.order-discount:

discountForPricingAdapterKey: ({ pricingAdapterKey }) => {
  if (pricingAdapterKey === 'shop.unchained.pricing.order-discount') {
    return { fixedRate: 10000 }; // 100.00 for currencies with two decimals
  }
  return null;
},
