Wrapper around javascript Date.
An attempt to implement the cool features similar to PHP's Carbon library in javascript.
Although moment.js is a pretty good, battle-tested library which I have used on many projects, I wanted something very similar to Carbon for one of my projects. Now I have been using Samay in some of my projects completely replacing moment.
Note This is just a wrapper around the javascript Date and nothing more. Samay also does not support localization as of now. Having said that, I would like to mention that Samay has not been tested for all edge cases.
npm install samay --saveThen in your build process require samay in any of your files like
//samay.js or whatever other file
require('samay')Once Samay.js is built through (only transpile to es5 for cross browser support is required) your build process, inclued Samay.js in your file (if not already bundled into your main/app.js). Samay is then available as a global (window.Samay = Samay).
Samay is written in ES 2015.
Detailed documentation is in progress, meanwhile just for a glimpse, Samay offers:
PS: Look at the tests for a better idea of all methods available.
let dt = new Samay('2017-01-01');
console.log(dt); //returns 2017-01-01 00:00:00 new Samay() //without any args it returns an instance representing the current date & time
Samay.now()
Samay.create('Y-m-d', '2000-06-21')
Samay.createFromFormat('Y-m-d g:i A', '2000-06-21 09:30 AM')Note: By default all methods manipulate the original Samay instance on which the method is called. If that is not
what you intend and want to preserve the original Samay instance then you must clone the original object/instance
like let dt1 = dt.clone().addDays().subtractMinutes() - here dt will not be mutated.
let dt = new Samay(2005,3,31,16,30,30,500);
dt.startOfDay().toString() //returns 2005-03-31 00:00:00
dt.endOfDay().toString() //returns 2005-03-31 23:59:59
dt.nextDay().toString() //returns 2005-04-01 09:30:15
dt.previousDay().toString() //returns 2005-03-30 09:30:15
dt.startOfMonth().toString() //returns 2005-03-01 09:30:15
dt.endOfMonth().toString() //returns 2005-03-31 09:30:15
//other manipulation methods
let dt = new Samay(2017,01,01,09,30,14,230);
dt.nextMonth() //returns 2017-02-01 09:30:15
dt.previousMonth() //returns 2016-12-01 09:30:15
dt.monthAfter(2) //returns 2017-03-01 09:30:15
dt.monthBefore(3) //returns 2016-10-01 09:30:15
dt.firstOfMonth('Friday') //returns the samay instance representing the 1st Friday of the month
dt.lastOfMonth('Monday') //returns the samay instance representing the last Monday of the month
dt.nthOfMonth(2,'Friday') //returns the samay instance representing the 2nd Friday of the month
dt.nextWeek() //returns 2017-01-08 09:30:15
dt.previousWeek() //returns 2016-12-25 09:30:15
dt.weekBefore(2) //returns 2016-12-18 09:30:15
dt.weekAfter(3) //returns 2017-01-22 09:30:15
dt.nextQaurter()
dt.previousQuarter()
dt.quarterBefore()

//similarly subtractMonths(), subtractDays() etc are also available corresponding to each of the add methods. let dt = new Samay('2000-05-25 10:45:20')
let dt1 = new Samay('2000-05-30 10:30:50')
dt.diffInDays(dt1) //returns -5 indicating that dt is 5 days before dt1
dt.diffInMilliseconds(dt1)
dt.diffInSeconds(dt1)
dt.diffInMinutes(dt1)
dt.diffInHours(dt1)
dt.diffInWeeks(dt1)
dt.diffInMonths(dt1)
dt.diffInYears(dt1)
dt.diffForHumans(dt1) //returns "5 days before"
dt.eq(dt1) //returns false eq <=> equals
dt.ne(dt1) //returns true ne <=> not equals
dt.lt(dt1) //returns true lt <=>less than
dt.lte(dt1) //returns true lte <=> less than or equals to
dt.gt(dt1) //returns false gt <=> greater than
dt.gte(dt1) //returns false gte <=> greater than or equals to
dt.between(dt1, dt2) //returns a boolean indicating whether dt falls between the dt1 and dt2
By default all comparision methods will check for equality of the date portion only. If you want to do a strict checking
by comparing the time value you may pass a second argument as true like dt.eq(dt1, true)
For between() , by default it does not include the boundaries i.e. it checks only for dt > dt1 and dt < dt2, if you want
to include the boundaries as well then pass ** true** as the third argument.
If you want to use the strict mode in between() then pass true as the fourth argument.
Samay supports many formats
let dt = new Samay('2010-03-15 09:30:15');
dt.format('Y-m-d') //returns 2010-03-15
