Benchmarking performance of Native Modules

Benchmarks on ReactNative & NativeScript use the same function to measure performance.

async function measure(name: string, action: () => Promise<void>) {
  const start = performance.now();

  await action();

  const stop = performance.now();
  console.log(`${stop - start} ms (${name})`);
}

For now we have only run benchmarks for awating Promises on Native Modules on iOS. We use the following function on both NativeScript & ReactNative.

const testPromise = async () => {
  for (let i = 0; i < 5000; i++) {
    await NativeModules.RNTestModuleAliased.testPromise();
  }
};
measure('promise', testPromise);

Running benchmarks

To run the benchmarks in NativeScript first setup your environment for NativeScript & React Native

Clone the repo

git clone https://github.com/OpenNative/open-native

Run basic setup commands for the monorepo

yarn setup

NativeScript

Install the hooks

yarn demo:hooks

Navigate to the demo app.

cd apps/demo

Run the app

ns run ios

ReactNative

Navigate to the demo-react-native app.

cd apps/demo-react-native

Install pods

pod install

Run the app from monorepo root.

yarn start:rni
