A comprehensive React Native bridge for Apple HealthKit with TypeScript support, advanced authorization, and flexible data queries

import { HealthKitBridge, QuantityTypeIdentifier, CategoryTypeIdentifier, HealthKitUnit, HEALTHKIT_IDENTIFIERS, HEALTHKIT_UNITS } from '../index';
// Example usage with specific TypeScript types
export async function exampleUsage() {
    const bridge = new HealthKitBridge();
    // Check availability
    const isAvailable = await bridge.checkAvailability();
    if (!isAvailable) {
        console.log('HealthKit not available');
        return;
    }
    // Request authorization with specific types
    const isAuthorized = await bridge.requestSelectiveAuthorization([
        QuantityTypeIdentifier.StepCount,
        QuantityTypeIdentifier.HeartRate,
        CategoryTypeIdentifier.SleepAnalysis
    ], []);
    if (!isAuthorized) {
        console.log('Permission denied');
        return;
    }
    // Fetch data with specific types - TypeScript will suggest the correct units!
    const steps = await bridge.getQuantitySamplesForDays(QuantityTypeIdentifier.StepCount, HealthKitUnit.count, // ✅ Autocomplete suggests 'count'
    1);
    const heartRate = await bridge.getQuantitySamplesForDays(QuantityTypeIdentifier.HeartRate, HealthKitUnit.beatsPerMinute, // ✅ Autocomplete suggests 'bpm'
    1);
    const sleep = await bridge.getCategorySamplesForDays(CategoryTypeIdentifier.SleepAnalysis, // ✅ Autocomplete suggests categorical types
    1);
    console.log('Steps:', steps);
    console.log('Heart rate:', heartRate);
    console.log('Sleep:', sleep);
}
// Example using constants to make it even easier
export async function exampleWithConstants() {
    const bridge = new HealthKitBridge();
    const heartRateData = await bridge.getQuantitySamplesForDays(HEALTHKIT_IDENTIFIERS.HeartRate, // ✅ Easier than typing the enum
    HEALTHKIT_UNITS.beatsPerMinute, // ✅ Easier than typing the enum
    7 // last 7 days
    );
    console.log('Heart rate history:', heartRateData);
}
// Example range query with specific types
export async function exampleRangeQuery() {
    const bridge = new HealthKitBridge();
    const startDate = '2024-01-01T00:00:00.000Z';
    const endDate = '2024-01-31T23:59:59.999Z';
    // TypeScript ensures the unit is correct for the type
    const stepsData = await bridge.getQuantitySamplesForRange(QuantityTypeIdentifier.StepCount, HealthKitUnit.count, // ✅ TypeScript ensures it's the correct unit
    startDate, endDate);
    console.log('January steps:', stepsData);
}
// TypeScript type advantages:
// • Autocomplete for identifiers and units
// • Compile-time type checking
// • Prevention of typos
// • Inline documentation
