# react-native-healthier

The healthiest way to interact with HealthKit in React Native.

## Warning: Don't use this yet. The API isn't totally settled yet and the code is a dumpster fire.

Healthier is different than other React Native libraries for Apple Health because Healthier provides an API that closely resembles the native HealthKit API. Ultimately Healthier allows you (when it's finished) to query any HealthKit data without the need to define new data accessor methods.

```TypeScript
import Healthier, {QuantityTypeIdentifier, Query, ignite} from 'react-native-healthier';

// Example: read HRV data from HealthKit
async function readHRVData(startDate: Date, limit?: number) {
  const isAvailable = await Healthier.isAvailable();
  if (!isAvailable) return;

  const sampleType = QuantityTypeIdentifier.HeartRateVariabilitySDNN;

  await Healthier.requestAuthorization({
    read: [sampleType],
  });

  const predicate = Query.compoundPredicate({
    type: 'And', 
    subpredicates: [
      Query.predicateForSamples({
        start: startDate
        options: ['StrictStartDate'],
      }),
      Query.predicateForObjectsWithDeviceProperty({
        key: 'Manufacturer',
        value: 'Apple Inc.',
      }),
      Query.predicateForObjectsWithDeviceProperty({
        key: 'Model',
        value: 'Watch',
      }),
      Query.predicateForObjectsWithDeviceProperty({
        key: 'HardwareVersion',
        value: ["Watch4,1", "Watch4,2", "Watch4,3", "Watch4,4"]
      }),
    ]
  });

  const query = Query.sampleQuery({
    sampleType,
    predicate,
    limit, 
    sortDescriptors: [Query.createSortDescriptor('SampleStartDate', true)],
  });

  const data = await Healthier.execute(query);
}
```
