Create, view or edit events in react native using the standard iOS / Android dialogs
Clone or download
Latest commit 5178edc Sep 29, 2018


This package alows you to start an activity (Android) or show a modal window (iOS) for adding, viewing or editing events in device's calendar. Through a promise, you can find out if a new event was added and get its id, or if it was removed. The functionality is provided through native modules and won't therefore work with Expo.

For managing calendar events without the UI for user to interact with, see react-native-calendar-events.

Getting started

Note: the readme covers v2, see this for the v1 docs.

npm install react-native-add-calendar-event --save


yarn add react-native-add-calendar-event

Mostly automatic installation

  1. react-native link react-native-add-calendar-event

  2. add NSCalendarsUsageDescription and NSContactsUsageDescription keys to your Info.plist file. The string value associated with the key will be used when asking user for calendar permission.

  3. rebuild your project

iOS note: If you use pods, react-native link will probably add the podspec to your podfile, in which case you need to run pod install. If not, please verify that the library is under link binary with libraries in the build settings in Xcode (see manual installation notes).

Quick example

See the example folder for a demo app.

import * as AddCalendarEvent from 'react-native-add-calendar-event';

const eventConfig = {
  // and other options

  .then((eventInfo: { calendarItemIdentifier: string, eventIdentifier: string }) => {
    // handle success - receives an object with `calendarItemIdentifier` and `eventIdentifier` keys, both of type string.
    // These are two different identifiers on iOS.
    // On Android, where they are both equal and represent the event id, also strings.
    // when { action: 'CANCELLED' } is returned, the dialog was dismissed
  .catch((error: string) => {
    // handle error such as when user rejected permissions

Creating an event

call presentEventCreatingDialog(eventConfig)

eventConfig object:

Property Value Note
title String
startDate String format: 'YYYY-MM-DDTHH:mm:ss.SSSZ'
endDate String format: 'YYYY-MM-DDTHH:mm:ss.SSSZ'
location String
allDay boolean
url String iOS only
notes String The notes (iOS) or description (Android) associated with the event.

The dates passed to this module are strings. If you use moment, you may get the right format via momentInUTC.format('YYYY-MM-DDTHH:mm:ss.SSS[Z]') the string may look eg. like this: '2017-09-25T08:00:00.000Z'.

More options can be easily added, PRs are welcome!

Editing an event

call presentEventEditingDialog(eventConfig)

eventConfig object:

Property Value Note
eventId String Id of edited event.
useEditIntent boolean Android only, see description below.

useEditIntent: ACTION_EDIT should work for editing events, according to android docs but this doesn't always seem to be the case as reported in the bug tracker. This option leaves the choice up to you. By default, the module will use ACTION_VIEW which will only show the event, but from there it is easy for the user to tap the edit button and make changes.

Viewing an event

call presentEventViewingDialog(eventConfig)

eventConfig object:

Property Value Note
eventId String Id of edited event.
allowsEditing boolean iOS only; docs
allowsCalendarPreview boolean iOS only; docs

Interpreting the results

The aforementioned functions all return a promise that resolves with information about what happened or rejects with an error.

Due to the differences in the underlying native apis, it is not trivial to come up with a unified interface that could be exposed to JS and the module therefore returns slightly different results on each platform (we can do better though, PRs are welcome!). The rules are:

  • presentEventCreatingDialog
situation result on both platforms
event is created { action: 'SAVED', eventIdentifier: string, calendarItemIdentifier: string }
event creation is cancelled { action: 'CANCELED' }
  • presentEventEditingDialog
situation result on iOS result on Android
event is edited { action: 'SAVED', eventIdentifier: string, calendarItemIdentifier: string } { action: 'CANCELED' }
event editing is cancelled { action: 'CANCELED' } { action: 'CANCELED' }
event is deleted { action: 'DELETED' } { action: 'DELETED' }
  • presentEventViewingDialog

On Android, this will lead to same situation as calling presentEventEditingDialog; the following table describes iOS only:

situation result on iOS
event modal is dismissed { action: 'DONE' }
user responded to and saved a pending event invitation { action: 'RESPONDED' }
event is deleted { action: 'DELETED' }

Configuring the navigation bar (iOS only)

The navigation bar appearance for all calls can be customized by providing a navigationBarIOS object in the config. The object has the following shape:

navigationBarIOS: {
  tintColor: string,
  barTintColor: string,
  backgroundColor: string,
  translucent: boolean,
  titleColor: string,

Please see the docs on tintColor, barTintColor, backgroundColor, translucent, titleTextAttributes (NSForegroundColorAttributeName)

Exported constants

Please note that SAVED, CANCELED, DELETED, DONE and RESPONDED constants are exported from the module. The constants are borrowed from iOS and are covered in EKEventViewAction docs and EKEventEditViewAction docs.

Note on the Date JS Object

It is recommended to not rely on the standard Date object and instead use some third party library for dealing with dates, such as moment.js because JavaScriptCore (which is used to run react-native on devices) handles dates differently from V8 (which is used when debugging, when the code runs on your computer).
