Enable HealthKit in your application's Capabilities
Compile and run

Usage

Just require the react-native-apple-healthkit module and you're ready to go!

var AppleHealthKit = require('react-native-apple-healthkit');

...

let options = {
    permissions: {
        read: ["Height", "Weight", "StepCount", "DateOfBirth", "BodyMassIndex"],
        write: ["Weight", "StepCount", "BodyMassIndex"]
    }
};

AppleHealthKit.initHealthKit(options: Object, (err: Object, res: Object) => {
    if(err) {
        console.log("error initializing healthkit: ", err);
        return;
    }
    // healthkit initialized...
});

When the module has been successfully initialized you can read and write HealthKit data

var AppleHealthKit = require('react-native-apple-healthkit');
var _ = require('lodash');

...

AppleHealthKit.getLatestWeight(null, (err: Object, weight: Object) => {
    if(err){
        console.log("error getting current weight: ", err);
        return;
    }
    // use weight.value ...
});

...

let options = {value: 200};
AppleHealthKit.saveWeight(options: Object, (err: Object, res: Object) => {
    if(err){
        console.log("error saving weight to healthkit: ", err);
        return;
    }
    // weight successfully saved
});

import AppleHealthKit from 'react-native-apple-healthkit';

...

// get the available permissions from AppleHealthKit.Constants object
const PERMS = AppleHealthKit.Constants.Permissions;

// setup healthkit read/write permissions using PERMS
const healthKitOptions = {
    permissions: {
        read:  [
            PERMS.StepCount,
            PERMS.Height,
        ],
        write: [
            PERMS.StepCount
        ],
    }
};

Options

Methods

`isAvailable`

Check if HealthKit is available on the device.

AppleHealthKit.isAvailable((err: Object, available: boolean) => {
    if(available){
        // ...
    }
});

`initHealthKit`

Initialize HealthKit. This will show the HealthKit permissions prompt for any read/write permissions set in the required options object.

Due to Apple's privacy model if an app user has previously denied a specific permission then they can not be prompted again for that same permission. The app user would have to go into the Apple Health app and grant the permission to your react-native app under sources tab.

For any data that is read from HealthKit the status/error is the same for both. This privacy restriction results in having no knowledge of whether the permission was denied (make sure it's added to the permissions options object), or the data for the specific request was nil (ex. no steps recorded today).

For any data written to HealthKit an authorization error can be caught. If an authorization error occurs you can prompt the user to set the specific permission or add the permission to the options object if not present.

If new read/write permissions are added to the options object then the app user will see the HealthKit permissions prompt with the new permissions to allow.

initHealthKit requires an options object with HealthKit permission settings

let options = {
    permissions: {
        read: ["Height", "Weight", "StepCount", "DateOfBirth", "BodyMassIndex"],
        write: ["Weight", "StepCount", "BodyMassIndex"]
    }
};

AppleHealthKit.initHealthKit(options: Object, (err: string, res: Object) => {
    if(err) {
        console.log("error initializing healthkit: ", err);
        return;
    }
    // healthkit is initialized...
    // now safe to read and write healthkit data...
});

`getBiologicalSex`

Get the biological sex (gender). If the BiologicalSex read permission is missing or the user has denied it then the value will be unknown. The possible values are:

Value	HKBiologicalSex
unknown	HKBiologicalSexNotSet
male	HKBiologicalSexMale
female	HKBiologicalSexFemale
other	HKBiologicalSexOther

AppleHealthKit.getBiologicalSex(null, (err: Object, res: Object) => {
    if(this._handleHealthKitError(err, 'getBiologicalSex')){
        return;
    }
	// res.value will be one of the values from the above table (Value column)
    // use res.value ...
});

`getDateOfBirth`

Get the date of birth.

On success, the callback function will be provided with a res object containing dob value: string (ISO timestamp), and age: number (age in years):

{
	value: '1986-09-01T00:00:00.000-0400',
	age: 29
}

AppleHealthKit.getDateOfBirth(null, (err: Object, res: Object) => {
    if(this._handleHealthKitError(err, 'getDateOfBirth')){
        return;
    }
    // use res.value ... (ex: '1986-09-01T12:20:30-04:00')
	// use res.age ... (ex: 29)
});

`getStepCount`

Get the aggregated total steps for a specific day (starting and ending at midnight).

An optional options object may be provided containing date field representing the selected day. If date is not set or an options object is not provided then the current day will be used.

let d = new Date(2016,5,27);
let options = {
    date: d.toISOString()
};

AppleHealthKit.getStepCount(options: Object, (err: Object, steps: Object) => {
    if(this._handleHealthKitError(err, 'getStepCount')){
        return;
    }
    // steps.value is the step count for day 'd'
});

`getDailyStepCountSamples`

Get the total steps per day over a specified date range.

getDailyStepCountSamples accepts an options object containing required startDate: ISO8601Timestamp and optional endDate: ISO8601Timestamp. If endDate is not provided it will default to the current time

let options = {
    startDate: (new Date(2016,5,1)).toISOString()  // required
    endDate:   (new Date()).toISOString()          // optional; default now
};

The function will be called with an array of elements. Each element is an object containing value, startDate, and endDate fields:

[
  { value: 8, startDate: '2016-07-09T00:00:00.000-0400', endDate: '2016-07-10T00:00:00.000-0400' },
  { value: 1923, startDate: '2016-07-08T00:00:00.000-0400', endDate: '2016-07-09T00:00:00.000-0400' },
  { value: 1802, startDate: '2016-07-07T00:00:00.000-0400', endDate: '2016-07-08T00:00:00.000-0400' },
  ...
]

 AppleHealthKit.getDailyStepCountSamples(options: Object, (err: Object, res: Array<Object>) => {
    if(this._handleHealthKitError(err, 'getDailyStepCountSamples')){
        return;
    }
    // 'res' is array of {value: number, startDate: string, endDate: string} objects
    // sorted ascending from startDate through endDate
    for(let i=0; i<res.length; ++i){
        let elem = res[i];
        let stepCount = elem.value;
        let day = elem.startDate;
		// ...
    }
});

`initStepCountObserver`

Setup an HKObserverQuery for step count (HKQuantityTypeIdentifierStepCount) that will trigger an event listenable on react-native NativeAppEventEmitter when the HealthKit step count has changed.

The initStepCountObserver method must be called before adding a listener to NativeAppEventEmitter. After the step count observer has been initialized you can listen to the NativeAppEventEmitter change:steps event and re-fetch relevent step count data in the event handler.

The initStepCountObserver method should be called after HealthKit has been successfully initialized (AppleHealthKit.initHealthKit has been called without error).

// import NativeAppEventEmitter from react-native
import {
  Navigator,
  View,
  ...
  NativeAppEventEmitter,
} from 'react-native';

...

// initialize the step count observer and add an event
// listener for 'change:steps' event after HealthKit has
// been successfully initialized.
AppleHealthKit.initHealthKit(HKOPTIONS, (err, res) => {
  if(this._handleHKError(err, 'initHealthKit')){
    return;
  }

  // initialize the step count observer
  AppleHealthKit.initStepCountObserver({}, () => {});

  // add event listener for 'change:steps' and handle the
  // event in the event handler function.
  //
  // when adding a listener, a 'subscription' object is
  // returned that must be used to remove the listener
  // when the component unmounts. The subscription object
  // must be accessible to any function/method/instance
  // that will be unsubscribing from the event.
  this.sub = NativeAppEventEmitter.addListener(
    'change:steps',
    (evt) => {
      // a 'change:steps' event has been received. step
      // count data should be re-fetched from HealthKit.
      this._fetchStepCountData();
    }
  );

  // other tasks to perform after HealthKit has been
  // initialized (fetch relevant HealthKit data).
  this._fetchStepCountData();
  this._fetchOtherRelevantHealthKitData();
  // ...
});

...

// when the component where the listener was added unmounts
// (or whenever the listener should be removed), call the
// 'remove' method of the subscription object.
componentWillUnmount() {
  this.sub.remove();
}

`saveSteps`

Save a step count sample.

A step count sample represents the number of steps during a specific period of time. A sample should be a precise as possible, with startDate and endDate representing the range of time the steps were taken in.

	if(this._handleHealthKitError(err, 'getBloodGlucoseSamples')){
		return;
	}
	// use samples ...
});

`getSleepSamples`

query for sleep samples.

each sleep sample represents a period of time with a startDate and an endDate. the sample's value will be either INBED or ASLEEP. these values should overlap, meaning that two (or more) samples represent a single nights sleep activity. see HealthKit SleepAnalysis reference documentation

the options object is used to setup a query to retrieve relevant samples. the options must contain startDate and may also optionally include endDate and limit options

let options = {
    startDate: (new Date(2016,10,1)).toISOString(),		// required
	  endDate: (new Date()).toISOString(),				// optional; default now
    limit:10,											// optional; default no limit
};

the callback function will be called with a samples array containing objects with value, startDate, and endDate fields

example usage

AppleHealthKit.getSleepSamples(options, (err: Object, samples: Array<Object>) => {
	if(this._handleHealthKitError(err, 'getSleepSamples')){
		return;
	}
	// use samples ...
});
