🚀 Quick Start

Here's a complete example to get you started:

import { IapticRN } from 'react-native-iaptic';

// 1. Initialize with your configuration
IapticRN.initialize({
  appName: 'app.example.com',
  publicKey: 'YOUR_PUBLIC_KEY',
  iosBundleId: 'com.yourcompany.app',
  products: [{
    id: 'premium_monthly',
    type: 'paid subscription',
    entitlements: ['premium']
  },
  {
    id: 'coins_100',
    type: 'consumable',
    tokenType: 'coins',
    tokenValue: 100
  }
]);

Using Subscription UI

The IapticSubscriptionView component provides a complete subscription management interface with purchase handling.

// In your root node, add the modal component
<IapticSubscriptionView
  entitlementLabels={{
    premium: {
      label: "Premium Features",
      detail: "Exclusive content and advanced tools"
    }
  }}
  onPurchaseComplete={() => {
    // Update app state after purchase
    setEntitlements(IapticRN.listEntitlements());
  }}
  termsUrl="https://yourdomain.com/terms"
/>

Props Reference

Prop	Type	Description
entitlementLabels	Record<string, { label: string, detail?: string }>	Labels and descriptions for each entitlement
onPurchaseComplete	() => void	Callback after successful purchase
termsUrl	string	URL for terms & conditions
theme	object	Customize colors (see IapticTheme)

Entitlement Management Example

// AppState.ts
interface AppState {
  entitlements: string[];
}

// In your component
<TouchableOpacity
  onPress={() => checkAccess('premium')}
  style={styles.button}
>
  <Text>
    Premium Access: {appState.entitlements.includes('premium') ? '✅' : '🔒'}
  </Text>
</TouchableOpacity>

Customization

Customize styles using the styles prop:

<IapticSubscriptionView
  styles={{
    productCard: {
      backgroundColor: '#FFFFFF',
      borderRadius: 12
    },
    ctaButton: {
      backgroundColor: '#4CAF50'
    }
  }}
/>

The component automatically handles:

• Landscape/portrait layouts
• Localization
• Purchase states
• Active subscription management
• Receipt validation

Manual Purchase Flow

// 4. Handle purchases
const offer = IapticRN.getProduct('premium_monthly')?.offers[0];
if (offer) {
  await IapticRN.order(offer);
}

// 5. Check access
if (IapticRN.checkEntitlement('premium')) {
  // Unlock premium features
}

💡 Core Concepts

Product Definitions

Products can be subscriptions, consumables, or non-consumables. Each product can grant one or more entitlements:

IapticRN.setProductDefinitions([
  // Subscription that unlocks premium features
  { 
    id: 'premium_monthly',
    type: 'paid subscription',
    entitlements: ['premium']
  },
  // Non-consumable that unlocks a specific feature
  {
    id: 'dark_theme',
    type: 'non consumable',
    entitlements: ['cool_feature']
  },
  // Consumable tokens/currency
  { 
    id: 'coins_100',
    type: 'consumable',
    tokenType: 'coins',
    tokenValue: 100
  }
]);

Purchase Flow

Handle purchases with proper error management:

try {
  await IapticRN.order(productOffer);
} catch (error) {
  showError(error);
}

Restore Purchases

Allow users to restore their previous purchases:

try {
  await IapticRN.restorePurchases((processed, total) => {
    console.log(`Processed ${processed} of ${total} purchases`);
  });
}
catch (error) {
  showError(error);
}

Event Handling

Listen for purchase and subscription updates:

// Listen for subscription updates
IapticRN.addEventListener('subscription.updated', (reason, purchase) => {
  console.log(`Subscription ${purchase.id} ${reason}`);
});

// Listen for pending purchase updates
IapticRN.addEventListener('pendingPurchase.updated', (pendingPurchase) => {
  console.log(`Purchase ${pendingPurchase.productId} is now ${pendingPurchase.status}`);
});

// Listen for purchase updates
IapticRN.addEventListener('purchase.updated', (purchase) => {
  console.log(`Purchase ${purchase.id} ${purchase.status}`);
});

Feature Access Control

Check if users have access to specific features:

// Check premium access
if (IapticRN.checkEntitlement('premium')) {
  showPremiumContent();
} else {
  showUpgradePrompt();
}

// List all active entitlements
const unlockedFeatures = IapticRN.listEntitlements();
// ['basic', 'premium', 'cool_feature']

Error Handling

function showError(error: Error | IapticError) {
  if (error instanceof IapticError) {
    trackAnalyticsEvent(error.code);
    if (error.severity === IapticSeverity.INFO) {
      console.log('Info:', error.localizedMessage);
      return;
    }
    Alert.alert(error.localizedTitle, error.localizedMessage);
  } else {
    Alert.alert('Unknown error', error.message);
  }
}

Troubleshooting

• If your app fails to load products, check that your XCode project contains the "In-App Purchase" capability (XCode -> Project -> Targets (your app name) -> Capabilities). Hit "+ Capability" and add the In-App Purchase capability if it's missing.
