🎯 API Reference

📜 Permissions Statuses in React Native Nitro Event Kit

Permission checks and requests resolve into one of the following statuses:

Return Value	Description
"unavailable"	This feature is not available on the current device or in this context.
"denied"	The user has not granted permission, but it is requestable.
"restricted"	The permission is restricted due to parental controls or device policies.
"fullAccess"	The permission has been granted, and the app has full access to the calendar.
"writeOnly"	The app can write to the calendar but cannot read existing events.
"notDetermined"	The user has not been asked for permission yet.

These statuses help determine whether the app can read, write, or modify calendar events. If the status is "denied" or "restricted", users must manually enable permissions in the device settings.

📌 Example Usage

✅ Checking Permission Status

To check the current status of calendar permissions, use:

import { NitroEventKitCalendarPermission } from 'react-native-nitro-event-kit';

const checkCalendarPermission = () => {
  const status = NitroEventKitCalendarPermission.getPermissionsStatus();
  console.log('Current permission status:', status);
};

🔄 Requesting Permission

To request calendar access from the user, use:

import { NitroEventKitCalendarPermission } from 'react-native-nitro-event-kit';

const requestCalendarPermission = async () => {
  try {
    const status = await NitroEventKitCalendarPermission.requestPermission();
    console.log('Updated permission status:', status);
  } catch (error) {
    console.error('Error requesting permission:', error);
  }
};

📆 Calendar Methods

Below are the methods available in React Native Nitro Event Kit, allowing you to interact with the iOS calendar system.

---

Retrieves all active calendars available on the device.

NitroEventKit.getActiveCalendars(): Promise<EventKitCalendar[]>

📌 Example Usage

import { NitroEventKit } from 'react-native-nitro-event-kit';

const getActiveCalendars = async () => {
  try {
    const calendars = await NitroEventKit.getActiveCalendars();
    console.log('Active Calendars:', calendars);
  } catch (error) {
    console.error('Error fetching calendars:', error);
  }
};

Get Monthly Calendar Events

  try {
    const events = await NitroEventKit.getMonthlyCalendarEvents(
      EventKitEntityType.Event,
    );
    console.log('Monthly Events:', events);
  } catch (error) {
    console.error('Error fetching monthly events:', error);
  }
};

Get Events in Date Range

Fetches calendar events within a specific date range.

NitroEventKit.getCalendarEventsByRange(options: RangeEventOptions): Promise<EventKitEvent[]>

📌 Example Usage

import {
  NitroEventKit,
  EventKitEntityType,
} from 'react-native-nitro-event-kit';
import dayjs from 'dayjs';

const getEventsByRange = async () => {
  const options = {
    startDate: dayjs().startOf('month').valueOf(),
    endDate: dayjs().endOf('month').valueOf(),
    entityType: EventKitEntityType.Event,
  };

  try {
    const events = await NitroEventKit.getCalendarEventsByRange(options);
    console.log('Events in Range:', events);
  } catch (error) {
    console.error('Error fetching events in range:', error);
  }
};

Create a New Event

Creates a new event in the specified calendar.

NitroEventKit.createEvent(options: CreateEventOptions): Promise<EventKitEvent>

📌 Example Usage

import { NitroEventKit } from 'react-native-nitro-event-kit';
import dayjs from 'dayjs';

const createEvent = async () => {
  const eventOptions = {
    title: 'Meeting with Team',
    location: 'Office',
    notes: 'Discuss project updates',
    startDate: dayjs().add(1, 'hour').valueOf(),
    endDate: dayjs().add(2, 'hour').valueOf(),
    calendarIdentifier: '66C97F38-EB2B-4F6F-9E51-EEE42646A7BC',
    isCalendarImmutable: false,
    scheduleAlarmMinutesBefore: 10,
    scheduleAlarm: true,
  };

  try {
    const newEvent = await NitroEventKit.createEvent(eventOptions);
    console.log('Event Created:', newEvent);
  } catch (error) {
    console.error('Error creating event:', error);
  }
};

Delete an Event

Deletes an event by its event identifier.

NitroEventKit.deleteEvent(eventIdentifier: string): Promise<boolean>

📌 Example Usage

import { NitroEventKit } from 'react-native-nitro-event-kit';

const deleteEvent = async (eventId: string) => {
  try {
    const success = await NitroEventKit.deleteEvent(eventId);
    console.log(success ? 'Event Deleted' : 'Failed to Delete Event');
  } catch (error) {
    console.error('Error deleting event:', error);
  }
};

import { NitroEventKit } from 'react-native-nitro-event-kit';

const openEventInCalendar = async (eventId: string) => {
  try {
    await NitroEventKit.openCalendarEvent(eventId);
    console.log('Calendar event opened successfully');
  } catch (error) {
    console.error('Error opening calendar event:', error);
  }
};
