Usage

import { InMemoryCouponRepository } from '@dhruvp13/promo-code-memory'
import { validateCoupon } from '@dhruvp13/promo-code-core'

const repo = new InMemoryCouponRepository({
  coupons: [
    {
      id: '1',
      code: 'SAVE20',
      isActive: true,
      startDate: '2024-01-01T00:00:00Z',
      endDate: '2099-01-01T00:00:00Z',
      rewardType: 'discount',
      discountType: 'percentage',
      discountValue: 20,
      appliesTo: ['coin'],
      globalUsageLimit: 0,
      globalUsageCount: 0,
      perUserLimit: 0,
      firstTimePurchaseOnly: false,
    },
  ],

const result = await validateCoupon(repo, {
  code: 'SAVE20',
  userId: 'user-1',
  purchaseType: 'coin',
  baseAmount: 5000,
})

Not for production use — state is in-process only and lost on restart. For production, implement CouponRepository against your database (see @dhruvp13/promo-code-adapters).
