React Native Modules

React Native Modules are a core feature of the React Native framework that allows developers to create native modules, which are JavaScript interfaces to native platform code (e.g., Objective-C/Swift for iOS, Java/Kotlin for Android). They enable access to device-specific APIs and functionalities not available in standard JavaScript, such as camera, sensors, or custom hardware integrations. This bridges the gap between React Native's cross-platform JavaScript layer and the underlying native platforms, enhancing app capabilities.

Also known as: Native Modules, RN Modules, React Native Native Modules, Native Bridge, Platform Modules

Why learn React Native Modules?

Developers should learn React Native Modules when building React Native apps that require native functionality beyond what the core framework or community libraries provide, such as integrating with proprietary hardware, using platform-specific APIs, or optimizing performance-critical tasks. It is essential for creating custom native components, handling complex animations, or accessing device features like Bluetooth or biometrics, ensuring apps can leverage full native power while maintaining a cross-platform codebase.
