⚠️ Notice

Starting from version 14.0.0, this library uses Nitro Modules for high-performance native bridge implementation. You must install react-native-nitro-modules alongside react-native-iap.

Compatibility (Nitro 14.x)

• react-native-iap@14.x (Nitro) requires React Native 0.79+.
• Stuck on RN 0.75.x or lower? Use the last pre‑Nitro version: npm i react-native-iap@13.1.0.
• Seeing Swift 6 C++ interop errors in Nitro (e.g., AnyMap.swift with cppPart.pointee.*)? Temporarily pin Swift to 5.10 for the NitroModules pod (see Installation docs) or upgrade RN and Nitro deps.
• Recommended: upgrade to RN 0.79+, update react-native-nitro-modules/nitro-codegen, then pod install and clean build.

More details and the Podfile snippet are in the docs: https://hyochan.github.io/react-native-iap/docs/installation#ios

Post Installation

Android Configuration

Add the OpenIAP Google library to your android/app/build.gradle dependencies:

dependencies {
    implementation "io.github.hyochan.openiap:openiap-google:1.1.0"
}

Kotlin Version Requirement: This library requires Kotlin 2.0+. Configure your project's Kotlin version:

In your root android/build.gradle:

buildscript {
    ext {
        kotlinVersion = "2.1.20"
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
    }
}

iOS Configuration

1. Install pods:

   cd ios && pod install

2. Add StoreKit capability to your iOS app in Xcode:

   • Open your project in Xcode
   • Select your app target
   • Go to "Signing & Capabilities"
   • Click "+ Capability" and add "In-App Purchase"

Expo Configuration

For Expo projects, add the plugin to your app.json or expo.json:

{
  "expo": {
    "plugins": [
      "react-native-iap",
      [
        "expo-build-properties",
        {
          "android": {
            "kotlinVersion": "2.1.20"
          }
        }
      ]
    ]
  }
}

Note: Expo projects require development build (dev-client) as this library contains native code.
