Basic Usage

The useEventsCalendar() hook takes one required argument: initialEvents, and one optional argument initialSelectedDate.

initialEvents is an array of CalendarEvent to place on the calendar whan it loads.

initialSelectedDate is the date on which the calendar will focus when it loads, this is today by default.

useEventsCalendar() uses two other hooks under the hood,
useCalendar: (initialSelectedDate?: Date) => UseCalendar and useEvents: (initialEvents: CalendarEvent[]) => UseEvents

For convenience, defaultCalendar and defaultEvents will satisfy types as an initializer for createContext.

All types are named exports.

``
import React, {createContext, useContext} from "react";

import useEventsCalendar, {UseCalendar, UseEvents, defaultCalendar, defaultEvents} from "use-events-calendar-react";

const initialEvents = [];

const initialSelectedDate = new Date();

cosnt EventsCalendarContext = createContext<{calendar: UseCalendar, calendarEvents: UseEvents}>(
{calendar: defaultCalendar, calendarEvents: defaultEvents}
)

const App = () => {

const {calendar, calendarEvents} = useEventsCalendar(initialSelectedDate, initialEvents);
