React Native In-App Purchase Helper is a React Native library designed to simplify in-app purchase flows for both iOS and Android. In-app purchases can sometimes be complex to implement, so this library aims to offer a streamlined and more flexible approach. It provides utility functions to manage in-app purchases, handle receipt verification seamlessly, and allows developers to integrate payment flows with shorter, more efficient code. With this package, you can reduce the complexity of IAP operations while maintaining full control over the process.

🚀 Getting Started

npm kullanarak yükleyin

  npm install react-native-in-app-purchase-helper

Import the helper functions into your project:

import {verifyTransaction,fetchPrices,createPaymentAndroid,createPaymentIOS} 
 from 'react-native-in-app-purchase-helper';

Fetching Product Prices and Defining Packages

const packageDetails = [
  {
    id: 'basic',
    androidSKUs: ['basic_android'],
    iosSKUs: ['basic_ios'],
  },
  {
    id: 'premium',
    androidSKUs: ['premium_android'],
    iosSKUs: ['premium_ios'],
  },
  {
    id: 'pro',
    androidSKUs: ['pro_android'],
    iosSKUs: ['pro_ios'],
  },
];

async function displayPackagePrices() {
  try {
    const prices = await fetchPrices(packageDetails);
    prices.forEach(pkg => {
      console.log(`Package: ${pkg.id}, Price: ${pkg.price}`);
    });
  } catch (error) {
    console.error('Error displaying prices:', error);
  }
}

Creating a Payment Method for Android

async function purchasePackage(packageId) {
  const selectedPackage = packageDetails.find(pkg => pkg.id === packageId);
  if (!selectedPackage) {
    console.error('Invalid package selected');
    return;
  }

  try {
    if (Platform.OS === 'android') {
      const purchase = await createPaymentAndroid(selectedPackage);
      console.log('Purchase successful:', purchase);
    } else if (Platform.OS === 'ios') {
      const ITUNES_SHARED_SECRET = 'your_itunes_shared_secret';
      const purchase = await createPaymentIos(selectedPackage, ITUNES_SHARED_SECRET);
      console.log('Purchase successful:', purchase);
    }
  } catch (error) {
    console.error('Error during purchase:', error);
  }
}

// For example, the user wants to purchase the premium package:
purchasePackage('premium');

Continuing a Payment

async function purchasePackage(packageId) {
  const selectedPackage = packageDetails.find(pkg => pkg.id === packageId);
  if (!selectedPackage) {
    console.error('Invalid package selected');
    return;
  }
  try {
    if (Platform.OS === 'android') {
      const purchase = await createPaymentAndroid(selectedPackage);
      console.log('Purchase successful:', purchase);
    } else if (Platform.OS === 'ios') {
      const ITUNES_SHARED_SECRET = 'your_itunes_shared_secret';
      const purchase = await createPaymentIos(selectedPackage, ITUNES_SHARED_SECRET);
      console.log('Purchase successful:', purchase);
    }
  } catch (error) {
    console.error('Error during purchase:', error);
  }
}
// For example, user wants to buy premium package:
purchasePackage('premium');

Verifying a Transaction (Only for IOS)

const isValid = await verifyTransaction(transactionReceipt, ITUNES_SHARED_SECRET);
if (isValid.valid) { 
  console.log('Purchase is valid.');
} else {
  console.error('Purchase is invalid.');
}

Usage Scenario:

Get Product Prices on App Startup and use to show it to the user

Show the prices of the products to the user by calling the getProductPrices(named for example) function at the beginning of your application. When User Wants to Buy a Product:

Have the user purchase the product of their choice by calling the launchPurchase(named for example) function. Perform Post-Purchase Actions:

Complete and verify the payment using the ProcessPayment(named for example) function.
