Integrating In-App Purchase (IAP) into a application mobile site is essential for monetizing content or offering premium features to users.
When it comes to developing cross-platform applications such as React Native and Cordova Capacitor, there are two main approaches: native implementation and the use of third-party plugins.
At NetDevicesWe master all approaches and will adapt to your existing app if it's already on the stores!
Implementation in React Native
The native implementation of IAP in React Native consists of using platform-specific APIs (iOS and Android) to manage purchases withinapplication. This requires writing platform-specific code, but it also offers greater control and flexibility over the purchasing process.

Advantages and disadvantages
Advantages :
- Total control By using the native API, you have total control over the purchasing process, and can manage errors and flows in a more specific way.
- Performance Native implementation is often faster in terms of performance, as it doesn't require any additional overlay.
- Compatibility with the latest features You can easily access the latest features and updates of the platform-specific DPI APIs.
Disadvantages:
- Complexity Native implementation can be more complex, as you'll need to write and maintain platform-specific code.
- Development time : Developing a native implementation can take longer than using existing plugins.
Sample code
Using Cordova Capacitor plugins
Cordova Capacitor lets you use existing plugins to integrate native functionality into a cross-platform application . To implement DPI, you can use Cordova plugins that support DPI for iOS and Android.
Advantages and disadvantages of Cordova Capacitor
Advantages :
- Ease of integration Using existing plugins reduces complexity and speeds up the development process.
- Unified approach You can use the same code to manage DPI on different platforms, simplifying maintenance.
- Plugin community : There's an active Cordova plugin community that can provide updates and additional support.
Disadvantages:
- Dependence on third-party plugins : You're dependent on third-party plugin updates and maintenance, which can sometimes cause compatibility problems with versions of Cordova or Capacitor.
- Functionality limitations Third-party plugins may not support all platform-specific features.
In conclusion
The choice between native implementation in React Native and the use of Cordova Capacitor plugins depends on your specific needs. application and your development preferences. If you need total control and maximum performance, native implementation may be preferable. However, if you're looking to speed up development and use unified functionality across different platforms, Cordova plugins may be an appropriate solution. In all cases, be sure to follow security best practices and respect each platform's policies for integrated purchases.
