availability-schedule

A simple availability schedule library for JS

Installation

npm install availability-schedule --save

Import

const AvailabilitySchedule = require('availability-schedule');

For TypeScript:

import AvailabilitySchedule = require('availability-schedule');

If that throws an error (e.g. TS1202: Import assignment cannot be used when targeting ECMAScript modules), try a regular import statement:

import AvailabilitySchedule from 'availability-schedule';

Usage

const schedule = new AvailabilitySchedule('2017-01-09T00:00:00Z', '2017-01-16T00:00:00Z'); // Second week of Jan 2017
schedule.addWeeklyRecurringAvailability('2017-01-04T09:00:00Z', '2017-01-04T17:00:00Z', [1, 2, 3, 4, 5]); // Mon-Fri 9am-5pm UTC, starting on Wed Jan 4th
schedule.addAvailability('2017-01-14T12:00:00Z', '2017-01-14T15:00:00Z'); // Sat Jan 14 12pm-3pm UTC

schedule.getAvailabilities('+0100');
/*

  {start: '2017-01-09T10:00:00+01:00', end: '2017-01-09T18:00:00+01:00'},

  {start: '2017-01-14T13:00:00+01:00', end: '2017-01-14T16:00:00+01:00'}
]

schedule.isAvailable('2017-01-14T15:00:00+01:00', '2017-01-14T16:00:00+01:00'); // true

Reference

The library is fully timezone-aware. Dates can be provided in any timezone and can be mixed.

Tip: Use the toISOString method of the Date class or the moment library to generate ISO 8601 date strings.

constructor (startDate, endDate)

  • startDate Start date of the schedule as an ISO 8601 string
  • endDate End date of the schedule as an ISO 8601 string

addAvailability (startDate, endDate)

  • startDate ISO 8601 string
  • endDate ISO 8601 string

addWeeklyRecurringAvailability (startDate, endDate, repeatWeekdays)

  • startDate ISO 8601 string
  • endDate ISO 8601 string
  • repeatWeekdays Array of integers that indicate the weekdays on which the availability is repeated. 1 = Mon, 7 = Sun (in the same time zone as startDate).

Start and end dates may be earlier than the start date passed to the constructor.

removeAvailability (startDate, endDate)

  • startDate ISO 8601 string
  • endDate ISO 8601 string

Use this to remove a time range from any existing availabilities. For example, call this for scheduled appointments or meetings.

getAvailabilities (timezone = '+0000')

  • timezone Accepts just the timezone offset such as "-05:00" as well as a full time stamp that includes the offset (e.g. "2000-01-01T00:00:00-04:00")

Returns all availabilities as an array of {start: date string, end: date string} objects in chronological order.

isAvailable (startDate, endDate)

  • startDate ISO 8601 string
  • endDate ISO 8601 string

Returns true if the given time range falls within any availability.
