Now

Now is a time toolkit for javascript

Overview

Now is inspire by Now(a time toolkit for golang). When I'm about to complete the code, I found that this is just a total toy. go's standard library time native support Format, Duration and so on. Format and i18n needs a huge amount of work. I found that moment had implemented them in a very elegant way. So I borrow it, respect and gratitude!

Install

Install with npm

npm install now.js

ES6/commonjs

// ES6
import Now from 'now.js';

// commonjs
var Now = require('now.js');

Using cdn

// default support 'en' and 'zh-cn'
<script type="text/javascript" src="https://unpkg.com/now.js/dist/nowjs.min.js"></script>

// or locale version support 118 languages
<script type="text/javascript" src="https://unpkg.com/now.js/dist/nowjs.locale.min.js"></script>

Examples

var now = new Now()

now.format() // "2017-11-20T22:23:00+08:00"
now.format('YYYY-MM-DD HH:mm:ss.SSS') // "2017-11-20 22:23:00.285"
now.format("dddd, MMMM Do YYYY, h:mm:ss a") // "Monday, November 20th 2017, 10:23:00 pm"

now.locale('zh-cn') // default support 'en' and 'zh-cn'
now.format("dddd, MMMM Do YYYY, h:mm:ss a") // "星期一, 十一月 20日 2017, 10:23:00 晚上"
now.elapse() // "10 天前"
// same as
now.timeAgo() // "10 天前"

// monday
now.monday() // "2017-11-20 00:00:00"

// isMonday
now.isMonday() // true

now.between(new Date(2008, 10, 10), new Date(2018, 10, 10)) // true

// UTC
now.UTC().format() // "2017-11-20T22:23:00+00:00"

now.beginningOfMinute()   // "2017-11-20 22:23:00"
now.beginningOfHour()     // "2017-11-20 22:00:00"
now.beginningOfDay()      // "2017-11-20 00:00:00"
now.beginningOfWeek()     // "2017-11-19 00:00:00"
now.firstDayMonday = true // Set Monday as first day, default is Sunday
now.beginningOfWeek()     // "2017-11-20 00:00:00"
now.beginningOfMonth()    // "2017-11-01 00:00:00"
now.beginningOfQuarter()  // "2017-10-01 00:00:00"
now.beginningOfYear()     // "2017-01-01 00:00:00"

now.endOfMinute()         // "2017-11-20 22:23:59.999"
now.endOfHour()           // "2017-11-20 22:59:59.999"
now.endOfDay()            // "2017-11-20 23:59:59.999"
now.endOfWeek()           // "2017-11-25 23:59:59.999"
now.firstDayMonday = true // Set Monday as first day, default is Sunday
now.endOfWeek()           // "2017-11-26 23:59:59.999"
now.endOfMonth()          // "2017-11-30 23:59:59.999"

now.endOfYear()           // "2017-12-31 23:59:59.999"

All the above functions return String type. You can pass 'self' to return Now instance:

var beginningOfMinute = now.beginningOfMinute('self') // return Now instance
beginningOfMinute.format('ddd, Ah') // "Mon, PM10"
beginningOfMinute.format('LLLL') // "Monday, November 20, 2017 10:23 PM"
beginningOfMinute.isMonday() // true
