Rx support with react-native-contacts-rx

• Preliminary iOS and Android support
• API subject to revision, changelog in release notes

• getAll (callback) - returns all contacts as an array of objects
• getAllWithoutPhotos - same as getAll on Android, but on iOS it will not return uris for contact photos (because there's a significant overhead in creating the images)
• getPhotoForId(contactId, callback) - returns a URI (or null) for a contacts photo
• addContact (contact, callback) - adds a contact to the AddressBook.
• updateContact (contact, callback) - where contact is an object with a valid recordID
• deleteContact (contact, callback) - where contact is an object with a valid recordID
• checkPermission (callback) - checks permission to access Contacts
• requestPermission (callback) - request permission to access Contacts

getAll is a database intensive process, and can take a long time to complete depending on the size of the contacts list. Because of this, it is recommended you access the getAll method before it is needed, and cache the results for future use.

Also there is a lot of room for performance enhancements in both iOS and android. PR's welcome!

var Contacts = require('react-native-contacts')

Contacts.getAll((err, contacts) => {
  if(err && err.type === 'permissionDenied'){
    // x.x
  } else {
    console.log(contacts)
  }
})

{
  recordID: '6b2237ee0df85980',
  company: "",
  emailAddresses: [{
    label: "work",
    email: "[email protected]",
  }],
  familyName: "Jung",
  givenName: "Carl",
  jobTitle: "",
  middleName: "",
  phoneNumbers: [{
    label: "mobile",
    number: "(555) 555-5555",
  }],
  thumbnailPath: 'content://com.android.contacts/display_photo/3',
  postalAddresses: 
    [ 
      {
        postCode: 'Postcooode',
        city: 'City',
        neighborhood: 'neighborhood',
        street: 'Home Street',
        formattedAddress: 'Home Street\nneighborhood\nCity Postcooode',
        label: 'work' 
      }
    ]
}

NOTE

• on Android the entire display name is passed in the givenName field. middleName and familyName will be "".

Currently all fields from the contact record except for thumbnailPath are supported for writing

var newPerson = {
  emailAddresses: [{
    label: "work",
    email: "[email protected]",
  }],
  familyName: "Nietzsche",
  givenName: "Friedrich",
}

Contacts.addContact(newPerson, (err) => { /*...*/ })

//contrived example
Contacts.getAll( (err, contacts) => {
  //update the first record
  let someRecord = contacts[0]
  someRecord.emailAddresses.push({
    label: "junk",
    email: "[email protected]",
  })
  Contacts.updateContact(someRecord, (err) => { /*...*/ })

  //delete the second record
  Contacts.deleteContact(contacts[1], (err) => { /*...*/ })
})

Update and delete reference contacts by their recordID (as returned by the OS in getContacts). Apple does not guarantee the recordID will not change, e.g. it may be reassigned during a phone migration. Consequently you should always grab a fresh contact list with getContacts before performing update and delete operations.

You can also delete a record using only it's recordID like follows: Contacts.deleteContact({recordID: 1}, (err) => {})}

The thumbnailPath is the direct URI for the temp location of the contact's cropped thumbnail image.

<Image source={{uri: contact.thumbnailPath}} />

run npm install react-native-contacts

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. add ./node_modules/react-native-contacts/ios/RCTContacts.xcodeproj
3. In the XCode project navigator, select your project, select the Build Phases tab and in the Link Binary With Libraries section add libRCTContacts.a

As of Xcode 8 and React Native 0.33 it is now necessary to add kit specific "permission" keys to your Xcode Info.plist file, in order to make requestPermission work. Otherwise your app crashes when requesting the specific permission. I discovered this after days of frustration.

Open Xcode > Info.plist > Add a key (starting with "Privacy - ...") with your kit specific permission. The value for the key is optional.

You have to add the key "Privacy - Contacts Usage Description".

• In android/settings.gradle

...
include ':react-native-contacts'
project(':react-native-contacts').projectDir = new File(settingsDir, '../node_modules/react-native-contacts/android')

• In android/app/build.gradle

...
dependencies {
    ...
    compile project(':react-native-contacts')
}

• register module (in android/app/src/main/java/com/[your-app-name]/MainApplication.java)

	...

	import com.rt2zz.reactnativecontacts.ReactNativeContacts; 	// <--- import module!

	public class MainApplication extends Application implements ReactApplication {
	    ...
		
	    @Override
	    protected List<ReactPackage> getPackages() {
	      return Arrays.<ReactPackage>asList(
	        new MainReactPackage(),
	        new ReactNativeContacts() 	// <--- and add package
	      );
	    }

    	...
    }

If you are using a version of RN before v0.21.0 please see the old instructions.

• add Contacts permission (in android/app/src/main/AndroidManifest.xml) (only add the permissions you need)

...
  <uses-permission android:name="android.permission.READ_CONTACTS" />
  <uses-permission android:name="android.permission.WRITE_CONTACTS" />
  <uses-permission android:name="android.permission.READ_PROFILE" />
...

checkPermission (callback) - checks permission to access Contacts.
requestPermission (callback) - request permission to access Contacts.

Usage as follows:

Contacts.checkPermission( (err, permission) => {
  // Contacts.PERMISSION_AUTHORIZED || Contacts.PERMISSION_UNDEFINED || Contacts.PERMISSION_DENIED
  if(permission === 'undefined'){
    Contacts.requestPermission( (err, permission) => {
      // ...
    })
  }
  if(permission === 'authorized'){
    // yay!
  }
  if(permission === 'denied'){
    // x.x
  }
})

These methods do not re-request permission if permission has already been granted or denied. This is a limitation in iOS, the best you can do is prompt the user with instructions for how to enable contacts from the phone settings page Settings > [app name] > contacts.

On android permission request is done upon install so this function will only show if the permission has been granted.

• android feature parity
• migrate iOS from AddressBook to Contacts
• implement get with options
• groups support
