  • MerchantName
  • Total
  • TransactionDate

​
Example Usage

import { validateReceipt } from '@your-package/models';

// Example receipt data
const receiptData = {
  MerchantName: "Local Store",
  Total: 50.00,
  TransactionDate: "2024-01-01",
  Items: [
    {
      Description: "Office Supplies",
      Quantity: 2,
      Price: 25.00,
      TotalPrice: 50.00
    }
  ],
  Payments: [
    {
      Method: "Credit Card",
      Amount: 50.00
    }
  ]
};

// Validate the receipt
const validatedReceipt = validateReceipt(receiptData);

// Access validated data through result property
console.log(validatedReceipt.result.Total);

​
Date Handling

The model accepts dates in multiple formats:

  • ISO 8601 datetime strings
  • YYYY-MM-DD format

All dates are converted to ISO format during validation.

​
Best Practices

  1. Always validate receipts:
const receipt = validateReceipt(receiptData);
  1. Access data through the result property:
const total = receipt.result.Total;
  1. Handle optional fields appropriately:
const tip = receipt.result.Tip || 0;
  1. Check arrays before processing:
const items = receipt.result.Items || [];
const payments = receipt.result.Payments || [];
  1. Calculate totals carefully:
const totalWithTip = (receipt.result.Total || 0) + (receipt.result.Tip || 0);
