How to set up react-native-iap with Expo dev client?

Add the react-native-iap plugin and expo-build-properties to your app.json, ensuring Kotlin version is set to 2.2.0+ for Android. Note that it requires a development build, not Expo Go, as native modules are needed.

react-native-iap vs RevenueCat which is better?

React Native IAP is open-source and OpenIAP-compliant, offering full control and no vendor lock-in, while RevenueCat is a managed service with more out-of-the-box features like analytics. Choose based on whether you prefer self-hosting or a SaaS solution.

Does react-native-iap support subscription renewals?

Yes, it supports recurring subscriptions with built-in receipt validation for both iOS and Android, handling renewal events through the unified API and error codes per the OpenIAP standard.

How to handle errors in react-native-iap?

Use the centralized error handling with platform-specific error code mapping, detailed in the documentation. Errors are OpenIAP-compliant, making debugging easier across iOS and Android.

Is react-native-iap compatible with React Native 0.72?

No, version 14.x requires React Native 0.79+ due to Nitro Modules. For RN 0.72, you must use the last pre-Nitro version, react-native-iap@13.1.0, which has limited updates.

What are Nitro Modules in react-native-iap?

Nitro Modules are a high-performance native bridge implementation using C++ core, reducing overhead and improving speed. They require additional setup, like installing react-native-nitro-modules, and can cause Swift compatibility issues.

How to validate receipts with react-native-iap?

It includes built-in receipt validation for iOS and Android, following OpenIAP standards. Implement it via the API methods for verifying purchases, with examples provided in the documentation for production use.

What is react-native-iap?

React Native IAP is a library that enables React Native developers to integrate in-app purchases into their iOS and Android applications. It solves the complexity of handling platform-specific purchase APIs by providing a single, type-safe JavaScript interface that works across both major mobile platforms.

Target Audience

React Native developers building mobile apps that require monetization through in-app purchases, subscriptions, or consumable products.

Value Proposition

Developers choose React Native IAP for its high performance via Nitro Modules, full TypeScript support, and compliance with the OpenIAP standard, which ensures consistent error handling and future interoperability across different IAP libraries.

Overview

Use Cases

Best For

Adding one-time purchases to a React Native app
Implementing subscription models in cross-platform mobile apps
Building Expo development client apps with native IAP functionality
Ensuring type-safe in-app purchase flows with TypeScript
Unifying error handling for IAP across iOS and Android
Leveraging modern React hooks for purchase state management

Not Ideal For

Teams using Expo Go for rapid prototyping without native builds
Projects stuck on React Native 0.75.x or lower that cannot upgrade
Developers preferring a simpler IAP setup without Nitro Modules complexity
Apps targeting platforms beyond iOS and Android, like web or desktop

Pros & Cons

Pros

Cross-Platform Unification

Provides a single API for iOS StoreKit 2 and Android Google Play Billing, abstracting platform differences as highlighted in the features, ensuring consistent development.

High Performance Architecture

Uses Nitro Modules for minimal overhead and efficient native bridge implementation, offering performance optimizations like caching and minimal re-renders.

Type-Safe Development

Full TypeScript support with comprehensive type definitions, enabling robust error prevention and better developer experience, as emphasized in the TypeScript-first approach.

Modern React Integration

Includes the useIAP hook for easy state management, simplifying integration with React hooks and reducing boilerplate code.

OpenIAP Compliance

Conforms to the OpenIAP specification for interoperability and standardized error handling, ensuring future-proofing and alignment with other libraries like expo-iap.

Cons

Steep Upgrade Requirements

Version 14.x mandates React Native 0.79+ and Kotlin 2.0+, forcing teams to update their entire stack, which can be time-consuming and disruptive.

Complex Native Integration

Relies on Nitro Modules, adding setup complexity and potential Swift/C++ interop errors, as noted in the compatibility warnings with Swift 6.

Limited Expo Support

Does not work with Expo Go, requiring development builds or bare React Native, which restricts rapid prototyping and increases setup overhead.

Dependency on Evolving Standard

Tied to the OpenIAP specification, which might introduce breaking changes or have a smaller ecosystem compared to established, proprietary alternatives.
