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

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:

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

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

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

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

public class MainApplication extends Application implements ReactApplication {

  // …

  @Override
  protected List getPackages() {
    @SuppressWarnings("UnnecessaryLocalVariable")
    List 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:

NSCalendarsUsageDescription
This app requires access to the calendar

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));

RNCalendarEvents.requestPermissions((readOnly = false));

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.

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.
