Turbo Native Modules & Codegen

Evaluate Turbo Native Modules & Codegen on release devices through startup, JS/UI frame rate, memory, networking, crash recovery, permissions, signing, and store requirements—not only a debug build. Recheck New Architecture and dependency compatibility on every upgrade.

Build a Complete Mental Model

Evaluate Turbo Native Modules & Codegen on release devices through startup, JS/UI frame rate, memory, networking, crash recovery, permissions, signing, and store requirements—not only a debug build. Recheck New Architecture and dependency compatibility on every upgrade.

Apply It in Production React Native

Test an original Turbo Native Modules & Codegen example on Android and iOS with small and large screens, font scaling, dark mode, keyboard and screen reader use, slow/offline networking, denied permissions, and background/foreground transitions. Use DevTools, tests, and a release build where relevant.

After This Lesson

• Explain the shared-code and platform boundary
• Build an example with loading, error, and accessibility states
• Verify one Android/iOS behavior with a test or profiler

import type { TurboModule } from 'react-native';
import { TurboModuleRegistry } from 'react-native';

export interface Spec extends TurboModule {
  readonly getDeviceName: () => string;
}

export default TurboModuleRegistry.getEnforcing<Spec>('NativeDeviceInfo');

Codegen can create typed native bindings from the module specification.
