@oleksii-pavlov/date-time is a TypeScript library that provides a DateTime class for handling date and time operations.
The DateTime class allows you to work with dates and times, manipulate them, perform comparisons, and convert between different formats.
You can install the package via npm:
npm install @oleksii-pavlov/date-timeYou can import the DateTime class into your TypeScript/JavaScript file as follows:
import { DateTime } from '@oleksii-pavlov/date-time'You can create DateTime instances using various constructors:
// Create a DateTime instance representing the current date and time
const now = new DateTime()
// Create a DateTime instance from milliseconds since epoch
const dateTimeFromMilliseconds = new DateTime({ years: 2024, months: 4, days: 22 })
// Create a DateTime instance from a Date object
const date = new Date()
const dateTimeFromDate = new DateTime(date)
// Create a DateTime instance from TimeData object
const timeData = {
years: 2024,
months: 4,
days: 22,
hours: 10,
minutes: 30,
seconds: 0,
milliseconds: 500
}
const dateTimeFromTimeData = new DateTime(timeData)Read more about TimeData below.
Returns a DateTime instance representing the specified duration before the current date and time.
const dateTime = new DateTime()
const duration = { days: 7 }
const dateTimeBefore = dateTime.getDateTimeBefore(duration)
console.log(dateTimeBefore)Returns a DateTime instance representing the specified duration after the current date and time.
const dateTime = new DateTime()
const duration = { months: 3 }
const dateTimeAfter = dateTime.getDateTimeAfter(duration)
console.log(dateTimeAfter)Returns a DateTime instance with the time components set to 0. (Returns the 00:00 time of the date)
const dateTime = new DateTime()
const normalizedDateTime = dateTime.normalizeDate()
console.log(normalizedDateTime)Checks if the given moment is earlier than or equal to the current moment.
const now = new DateTime()
const oneSecondAgo = new DateTime(now.getTimeInMilliseconds() - 1000)
console.log(now.isMomentEarlier(oneSecondAgo)) // trueChecks if the given moment is later than to the current moment.
const now = new DateTime()
const oneSecondLater = new DateTime(now.getTimeInMilliseconds() + 1000)
console.log(now.isMomentLater(oneSecondLater)) // trueReturns a TimeData object containing the date and time components.
const dateTime = new DateTime()
const timeData = dateTime.getTimeData()
console.log(timeData)Returns the JavaScript Date object representing the date and time.
const dateTime = new DateTime()
const date = dateTime.getDate()
console.log(date)Returns the number of milliseconds.
const dateTime = new DateTime()
const milliseconds = dateTime.getTimeInMilliseconds()
console.log(milliseconds)TimeData is an object than contains data about date and time.
interface TimeData {
years?: number
months?: number
days?: number
hours?: number
minutes?: number
seconds?: number
milliseconds?: number
}In DateTime constructor TimeData is one of the possible arguments. For Date properties years, months, days default values are today values. For Time properties hours, minutes, seconds, milliseconds default values are 0 (00:00 time)
