ExtDate

ExtDate is a simple and lite module to deal with Date object in javascript (and typescript), strongly inspired by Rails "Date" and "Time" objects.

Installation and Usage

npm

npm install extdate

To import the ExtDate functionality:

import { ExtDate } from 'extdate'

// create ExtDate instance from year, month and day
let date: ExtDate = new ExtDate(2017, 3, 8);

// create ExtDate instance from today's date
let today: ExtDate = new ExtDate();

// create ExtDate instance from javascript's Date object
let dateFromJS: ExtDate = new ExtDate(new Date());
