Utilities

The SDK provides various utility functions for consent management, data transformation, browser context handling, and other common operations.

checkConsent()

Checks if all required consent types have been granted by the customer.

function checkConsent(
  requiredConsents: ConsentType[],
  canTrack: any,
  analytics: any
): boolean

Parameters:

requiredConsents - Array of consent types that must be granted
canTrack - Hydrogen’s canTrack function from analytics
analytics - Hydrogen’s analytics instance

Returns: true if all required consents are granted, false otherwise Usage:

import { checkConsent, CONSENT_TYPES } from '@glood/hydrogen';

// Check if analytics consent is granted
const canSendAnalytics = checkConsent(
  [CONSENT_TYPES.ANALYTICS],
  canTrack,
  analytics
);

// Check multiple consent types
const canSendMarketing = checkConsent(
  [CONSENT_TYPES.ANALYTICS, CONSENT_TYPES.MARKETING],
  canTrack,
  analytics
);

if (canSendAnalytics) {
  // Send analytics pixel
}

Implementation Details:

export function checkConsent(
  requiredConsents: ConsentType[],
  canTrack: any,
  analytics: any
): boolean {
  if (!requiredConsents || requiredConsents.length === 0) {
    return true; // No consent required
  }

  return requiredConsents.every(consentType => {
    switch (consentType) {
      case 'analytics':
        return analytics.customerPrivacy?.analyticsProcessingAllowed();
      case 'marketing':
        return analytics.customerPrivacy?.marketingAllowed();
      case 'preferences':
        return analytics.customerPrivacy?.preferencesProcessingAllowed();
      case 'sale_of_data':
        return analytics.customerPrivacy?.saleOfDataAllowed();
      default:
        return false;
    }
  });
}

      queue.push({ endpoint, data });

      clearTimeout(timeoutId);
      timeoutId = setTimeout(() => {
        const pixelQueue = getPixelQueue();
        queue.forEach(item => pixelQueue.add(item));
        queue.length = 0; // Clear queue
      }, delay);
    }
  };
}

Testing Utilities

Mock Analytics

      analyticsProcessingAllowed: () => consents.analytics ?? true,
      marketingAllowed: () => consents.marketing ?? false,
      preferencesProcessingAllowed: () => consents.preferences ?? false,
      saleOfDataAllowed: () => consents.sale_of_data ?? false,
    },
    subscribe: jest.fn(),
    canTrack: jest.fn(() => true),
  };
}

// Usage in tests
const mockAnalytics = createMockAnalytics({
  analytics: true,
  marketing: false,
});

const canSend = checkConsent([CONSENT_TYPES.ANALYTICS], null, mockAnalytics);
expect(canSend).toBe(true);
