What is a React Native Native Module?

A Native Module is a set of native functions that are available in JavaScript. It acts as a bridge, allowing your React Native app to access platform-specific APIs like Bluetooth, sensors, or existing native SDKs.

How do I troubleshoot a 'Module Not Found' error in iOS?

Common fixes include clearing the build folder, re-running 'pod install' in the ios directory, and ensuring the module is correctly linked via autolinking or manual configuration in the Xcode workspace.

Can I use Swift for my native modules?

Yes, you can write native modules in Swift. It requires an Objective-C bridging header and marking your classes and methods with @objc to make them visible to the React Native runtime.

What is the difference between the Bridge and JSI?

The traditional Bridge uses asynchronous JSON communication, which can be a bottleneck. JSI (JavaScript Interface) allows JS to hold a reference to C++ host objects and invoke methods directly, enabling much faster communication.

Mobile Development

Bridges JavaScript and native code by facilitating the creation, integration, and debugging of React Native native modules and UI components.

소개

The React Native Native Modules Expert skill provides specialized guidance for developers working at the intersection of JavaScript and native mobile platforms. It offers deep expertise in both the legacy Bridge architecture and the New Architecture, including Turbo Modules, Fabric, and JSI. This skill assists in writing custom modules using Swift, Objective-C, Kotlin, or Java, implementing autolinking, and handling complex platform-specific APIs. It is particularly useful when integrating third-party SDKs, optimizing performance-critical operations, or troubleshooting native-level crashes and configuration errors in iOS and Android environments.
