Yes, it is possible to add existing native modules to a React Native app. React Native provides a bridge that allows you to write native code in Objective-C, Java, or Swift, and communicate with it from the JavaScript codebase.
To add an existing native module to your React Native app, you need to follow these steps:
1. Create a bridge module
Create a new module that acts as a bridge between your native code and JavaScript code. This module will expose the native functionality to JavaScript through methods and callbacks.
2. Implement the native code
Implement the desired functionality in the native code using the appropriate language and framework. This can be done by creating a new class or modifying an existing one.
3. Register the module
Register the bridge module in the React Native app by adding it to the package list. This will make the module available to the JavaScript code.
4. Use the module in JavaScript
Now, you can import and use the module in your JavaScript code. You can call the native methods and receive callbacks from the native code.
By following these steps, you can seamlessly integrate existing native modules into your React Native app and leverage the power of both JavaScript and native code.
