Capacitor HealthKit Plugin

❤️ Capacitor plugin to retrieve data from HealthKit ❤️

Disclaimer : for now only some of the HK data base, in the future the retrieve base will be bigger !

Getting Started

Prerequisites

• Add HealthKit to your Xcode project (section signing & capabilities)

• ADD Privacy - Health Share Usage Description to your Xcode project
• ADD Privacy - Health Update Usage Description to your Xcode project

You can simply put this into the info.plist file

	<key>NSHealthShareUsageDescription</key>
	<string>Read Health Data</string>
	<key>NSHealthUpdateUsageDescription</key>
	<string>Read Health Data</string>

Installing

Do

npm i --save @perfood/capacitor-healthkit

Then

npx cap update

And if you use Ionic or Angular, here a example setup:

in your .ts file add this:

import {
  ActivityData,
  CapacitorHealthkit,
  OtherData,
  QueryOutput,
  SampleNames,
  SleepData,
} from '@perfood/capacitor-healthkit';

const READ_PERMISSIONS = ['calories', 'stairs', 'activity', 'steps', 'distance', 'duration', 'weight'];

and then you can create async functions like this:

  public async requestAuthorization(): Promise<void> {
    try {
      await CapacitorHealthkit.requestAuthorization({
        all: [''],
        read: READ_PERMISSIONS,
        write: [''],
      });

    } catch (error) {
      console.error('[HealthKitService] Error getting Authorization:', error);
    }
  }

  private async getActivityData(
    startDate: Date,
    endDate: Date = new Date(),
  ): Promise<QueryOutput<ActivityData>> | undefined {
    try {
      const queryOptions = {
        sampleName: SampleNames.WORKOUT_TYPE,
        startDate: startDate.toISOString(),
        endDate: endDate.toISOString(),
        limit: 0,
      };

      return await CapacitorHealthkit.queryHKitSampleType<ActivityData>(queryOptions);
    } catch (error) {
      console.error(error);

      return undefined;
    }
  }

so you can use the plugin for example with the call CapacitorHealthkit.queryHKitSampleType(...

And you're all set ! 👍

requestAuthorization(...)

requestAuthorization(authOptions: AuthorizationQueryOptions) => Promise<void>

This functions will open the iOS Screen to let users choose their permissions. Keep in mind as developers, if the access has been denied by the user we will have no way of knowing - the query results will instead just be empty arrays.

Param	Type	Description
authOptions	AuthorizationQueryOptions	These define which access we need. Possible Options include ['calories', 'stairs', 'activity', 'steps', 'distance', 'duration', 'weight'].

---

queryHKitSampleType(...)

queryHKitSampleType<T>(queryOptions: SingleQueryOptions) => Promise<QueryOutput<T>>

This defines a query to the Healthkit for a single type of data.

Param	Type	Description
queryOptions	SingleQueryOptions	defines the type of data and the timeframe which shall be queried, a limit can be set to reduce the number of results.

Returns: Promise<QueryOutput<T>>

---

isAvailable()

isAvailable() => Promise<void>

This functions resolves if HealthKitData is available it uses the native HKHealthStore.isHealthDataAvailable() funtion of the HealthKit .

---

multipleQueryHKitSampleType(...)

multipleQueryHKitSampleType(queryOptions: MultipleQueryOptions) => Promise<any>

This defines a query to the Healthkit for a single type of data. This function has not been tested.

Param	Type	Description
queryOptions	MultipleQueryOptions	defines the sample types which can be queried for

Returns: Promise<any>

---

isEditionAuthorized(...)

isEditionAuthorized(queryOptions: EditionQuery) => Promise<void>

Checks if there is writing permission for one specific sample type. This function has not been tested.

Param	Type	Description
queryOptions	EditionQuery	defines the sampletype for which you need to check for writing permission.

---

multipleIsEditionAuthorized()

multipleIsEditionAuthorized() => Promise<void>

Checks if there is writing permission for multiple sample types. This function has not been tested - and usually needs a parameter to be able to answer.

---

Interfaces

AuthorizationQueryOptions

Used for authorization of reading and writing access.

Prop	Type
read	string[]
write	string[]
all	string[]

QueryOutput

This interface is used for any results coming from HealthKit. It always has a count and the actual results.

Prop	Type
countReturn	number
resultData	T[]

SingleQueryOptions

This extends the Basequeryoptions for a single sample type.

Prop	Type
sampleName	string

MultipleQueryOptions

This extends the Basequeryoptions for a multiple sample types.

Prop	Type
sampleNames	string[]

EditionQuery

This is used for checking writing permissions.

Prop	Type
sampleName	string
