React Native Calendar Events

A React Native module to help access and save events to iOS and Android calendars.

Getting started

This package assumes that you already have a React Native project or are familiar with React Native. If not, checkout the official documentation for more details about getting started with React Native.

Support

version	react-native version
2.0.0+	0.60.0+
pre 2.0.0+	0.40.0+

For 0.59-, you should use jetify -r

Installation

$ npm install --save react-native-calendar-events
# --- or ---
$ yarn add react-native-calendar-events

Don't forget going into the ios directory to execute a pod install.

🆘 Manual linking

Because this package targets React Native 0.60.0+, you will probably don't need to link it manually. Otherwise if it's not the case, follow this additional instructions:

👀 See manual linking instructions

iOS

Add this line to your ios/Podfile file, then run pod install.

target 'YourAwesomeProject' do
  # …
  pod 'RNCalendarEvents', :path => '../node_modules/react-native-calendar-events'
end

Android

1 - Add the following lines to android/settings.gradle:

include ':react-native-calendar-events'
project(':react-native-calendar-events').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-calendar-events/android')

2 - Add the implementation line to the dependencies in android/app/build.gradle:

dependencies {
  // ...
  implementation project(':react-native-calendar-events')
}

3 - Add the import and link the package in MainApplication.java:

import com.calendarevents.RNCalendarEventsPackage; // <- add the RNCalendarEventsPackage import

public class MainApplication extends Application implements ReactApplication {

  // …

  @Override
  protected List<ReactPackage> getPackages() {
    @SuppressWarnings("UnnecessaryLocalVariable")
    List<ReactPackage> packages = new PackageList(this).getPackages();
    // …
    packages.add(new RNCalendarEventsPackage());
    return packages;
  }

  // …
}

iOS specific instructions

Add RNCalendarEvents, as well as EventKit.framework to project libraries if not already done.

Setting up privacy usage descriptions may also be required depending on which iOS version is supported. This involves updating the Property List, Info.plist, with the corresponding key for the EKEventStore api. Info.plist reference.

For updating the Info.plist key/value via XCode, add a Privacy - Calendars Usage Description key with a usage description as the value. Resulting change to Info.plist should look something like:

<key>NSCalendarsUsageDescription</key>
<string>This app requires access to the calendar</string>

API

The following API allows for interacting with both iOS and Android device calendars. See the full list of available event fields.

import RNCalendarEvents from "react-native-calendar-events";

checkPermissions

Get calendar authorization status. You may check for the default read/write access with no argument, or read-only access on Android by passing boolean true. iOS is always read/write.

RNCalendarEvents.checkPermissions((readOnly = false));

Returns: Promise

• fulfilled: String - denied, restricted, authorized or undetermined
• rejected: Error

requestPermissions

Request calendar authorization. Authorization must be granted before accessing calendar events.

RNCalendarEvents.requestPermissions((readOnly = false));

(readOnly is for Android only, see below)

Android note: this is necessary for targeted SDK of >=23. iOS note: This method will crash, if you didn't update Info.plist. Follow carefully installation instruction.

Returns: Promise

• fulfilled: String - denied, restricted, authorized or undetermined
• rejected: Error

Read-Only requestPermissions (Android only)

⚠️ Note that to restrict to read-only usage on Android (iOS is always read/write) you will need to alter the included Android permissions as the AndroidManifest.xml is merged during the Android build.

You do that by altering your AndroidManifest.xml to "remove" the WRITE_CALENDAR permission with an entry like so:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  >
  <!-- ... -->
  <uses-permission tools:node="remove" android:name="android.permission.WRITE_CALENDAR" />

RNCalendarEvents.saveCalendar(calendar);

⚠️ When you want to save a calendar, you need to use a valid source (find using findCalendars).

Returns: Promise

• fulfilled: Object | null - Found event with unique id.
• rejected: Error

fetchAllEvents

Fetch all calendar events. Returns a promise with fulfilled found events.

RNCalendarEvents.fetchAllEvents(startDate, endDate, calendars);

To update an event, the event id must be defined. - wiki guide

RNCalendarEvents.saveEvent(title, {
  id: "FE6B128F-C0D8-4FB8-8FC6-D1D6BA015CDE",
});

Example for saveEvent

Creating events is fairly straightforward. Hopefully the following explanation can help.

Basic saveEvent

For both iOS and Android the pattern is simple; the event needs a title as well as a startDate and endDate. The endDate should also be a date later than the startDate.

RNCalendarEvents.saveEvent('Title of event', {
  startDate: '2016-08-19T19:26:00.000Z',
  endDate: '2017-08-19T19:26:00.000Z'
}) 

Specify a calendar saveEvent

The example above will simply save the event to your devices default calendar. If you wish to control which calendar the event is saved to, you must provide the calendarId. This will ensure your event is saved to an expected calendar.

RNCalendarEvents.saveEvent('Title of event', {
  calendarId: '141',
  startDate: '2016-08-19T19:26:00.000Z',
  endDate: '2017-08-19T19:26:00.000Z'
}) 

Additional fields with saveEvent

There are also other writable fields available. For example, you may wish to specify the location of the event or add additional notes for the event. Complete list of fields can be found in the wiki.

RNCalendarEvents.saveEvent('Title of event', {
  calendarId: '141',
  startDate: '2016-08-19T19:26:00.000Z',
  endDate: '2017-08-19T19:26:00.000Z',
  location: 'Los Angeles, CA',
  notes: 'Bring sunglasses'
}) 

removeEvent

Removes calendar event.

RNCalendarEvents.removeEvent(id, options);

Arguments:

• id: String - The id of the event to remove.
• options: Object - Options specific to event removal.

Returns: Promise

• fulfilled: Bool - Successful
• rejected: Error

Troubleshooting

These are some common issues you may run into while using react-native-calendar-events library. If you encounter something that is not listed here, try searching in GitHub issues of react-native-calendar-events.

After saving an event, it disappear form the calendar

This might be related to a sync issue. You need to be sure that the event you saved is matching what your device will keep in sync.

For iOS, you might have not all event synced. You might need to update this iOS settings in Settings > Calendar > Sync > All Events. If that's not enough, it might be worth checking iOS iCloud sync documentation.
For Android, you can have a look to Google Calendar sync problems documentation.

Duplicated events after editing and saving an event

Another symptom of syncing issue. See the issue above. Note that on Android, saveEvent accepts an additional option sync (boolean) to prevent syncing issues.
