Installation

or

yarn add sla_work_time

Usage

import { setSkipDays, addMinutes, configure, utils } from 'sla_work_time';

configure({
  // Setting work hours as 8:30AM to 5:30PM
  startAM: 8.5,
  endPM: 17.5,
});

setSkipDays([
  // Add DISTINCT holidays/days to exclude in { startDate, endDate (optional) } format.
  {
    startDate: '2022-11-25',
  },
  {
    startDate: '2022-11-29',
    endDate: '2022-11-30',
  },
  {
    startDate: '2022-12-02',
    endDate: '2022-12-12',
  },
]);

// Supports Date[] format (does internal duplicate removal->sorting->parsing this way)
// setSkipDays(['2022-12-01', '2022-12-02', '2022-12-03', '2022-12-05'])

const newDate = addMinutes('2022-11-28T16:18:44', 3600);

console.log(utils.formatDate(newDate, 'YYYY-MM-DDTHH:mm:ss')); // 2022-12-19T13:18:00

! NOTE !

To keep the system's list of holidays up-to-date, the setSkipDays function should be periodically called to update the in-memory list. This can be done either through an ETL job or periodic API calls to inject updated holiday information into the system. The service layer of the system is responsible for handling these updates.

toNextWorkTime	(date: DateTime, fixTime: Boolean = true)	Gets the given date back to valid work day and hours if it's not
validateSkipDay	(date: DateTime, fixTime: Boolean = true)	Gets the date out of holiday (if it's in one)

Description

These exposed functions add durations to a date considering work hours, week ends and skip days(holidays). For example, adding 25 minutes to the date Friday 05:55PM would result in Monday 09:20AM for [Mon-Fri] & [9AM - 6PM] work hour settings.
