App-Entwicklung: Native Module Integration
React Native covers most app requirements through the JavaScript ecosystem – but some features require deep access to native platform APIs that no ready-made package provides. We write native modules in Swift, Kotlin, and Objective-C and integrate them seamlessly into your React Native app, giving you access to any device capability without giving up cross-platform advantages.
Challenges you'll recognise
- Your React Native app needs access to a proprietary hardware SDK for which no ready-made package exists.
- An existing native library needs to be embedded in your React Native app without migrating the entire app to native development.
- Performance suffers at a specific point in the app due to too many asynchronous bridge calls – a synchronous Turbo Module would solve it.
When Native Modules?
Native modules are needed when no maintained package exists, a specific hardware feature is required (special Bluetooth profiles, proprietary SDKs), or existing native libraries must be embedded in the React Native app. We always check whether a ready-made package suffices before writing native code.
Turbo Modules
The new React Native Architecture uses Turbo Modules for significantly more performant native bridge communication. We implement native modules directly as Turbo Modules when you are on the new architecture – for synchronous calls and type-safe interfaces between JavaScript and native code.
iOS and Android
We implement native modules for both platforms: Swift or Objective-C for iOS, Kotlin or Java for Android. The JavaScript API is identical on both platforms; the implementation underneath is platform-specific. This keeps your React Native code platform-agnostic.
Testing and Debugging
Native modules are particularly error-prone because they bridge the gap between JavaScript and native code. We write unit tests for the native implementations and integrate logging mechanisms that make problems at the bridge boundary visible.
Good to know
Bridge vs. Turbo Module
Classic native modules communicate asynchronously over the JavaScript Bridge. Turbo Modules (new architecture) enable synchronous calls and type-safe interfaces – significantly more performant for frequently called native functions.
Swift, Kotlin, TypeScript
We write iOS implementations in Swift, Android implementations in Kotlin, and the JavaScript API in TypeScript. Each layer in the language optimised for it.
Package-First Approach
Before writing native code, we always check whether a maintained open-source package meets the requirement. Custom native modules are a last resort, not a first step.
Frequently asked questions
When should I use a ready-made package rather than writing a native module?
Can native modules work with the new React Native Architecture?
Do I need to pay for two separate implementations for iOS and Android?
