How do I display todays date in Node.js Jade?

Question

I am new to Node.js and Jade and I have tried to use #{Date.now()} and it's giving me numbers. How do I display the date in mm/dd/yy format?

Answer 1

add the class .post-date to a tag holding the date

document.addEventListener('DOMContentLoaded', function() {
    var list = document.getElementsByClassName('post-date');
                // get the number of selected elements

                // iterate over elements and output their HTML content
                for (var i=0; i<list.length; i++){
                    //console.log(list[i].innerHTML);
                    var string=list[i].innerHTML;
                    var length = 15;
                    var trimmedString = string.substring(0, length);
                    list[i].innerHTML=trimmedString ;
                }

})

I found a solution 1.Create a function in pug using - syntax 2.pass the varible to the function when pug.js is binding variables to the pug template

    -function prettyDate(dateString){
                        -var date = new Date(dateString);
                        -var d = date.getDate();
                        -var monthNames = [ "Jan", "Feb", "Mar", "Apr", "May", "Jun","Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ];
                        -var m = monthNames[date.getMonth()];
                        -var y = date.getFullYear();
                        -return d+' '+m+' '+y;
                    -}
3.span.post-date #{prettyDate(val.date)};

Answer 3

This is old, but I do the following:

return (new Date()).toLocaleDateString()

Returns a date 'mm/dd/yyyy' format, in no additional libs required.

Answer 4

I actually started using date-util which is 2 parts both clientside and server side.

URL https://github.com/JerrySievert/node-date-utils

Using within a Browser

<script type="text/javascript" src="date-utils.min.js"></script>

Using with Node.js

$ npm install date-utils

require('date-utils');

Note: This did not work in the REPL before Node.js 0.6 due to how Node.js handles context in the REPL.

Date.compare(date1, date2); // -1 if date1 is smaller than date2, 0 if equal, 1 if date2 is smaller than date1
Date.equals(date1, date2); // true/false if date1 is equal to date2

Date.getDayNumberFromName(name); // su/sun/sunday - 0, mo/mon/monday - 1, etc
Date.getMonthNumberFromName(name); // jan/january - 0, feb/february - 1, etc
Date.isLeapYear(year); // true/false whether the year is a leap year
Date.getDaysInMonth(monthNumber); // number of days in the month

Instance Methods

d.clone(); // returns a new copy of date object set to the same time
d.getMonthAbbr(); // abreviated month name, Jan, Feb, etc
d.getMonthName(); // fill month name, January, February, etc
d.getUTCOffset(); // returns the UTC offset
d.getOrdinalNumber(); // day number of the year, 1-366 (leap year)
d.clearTime(); // sets time to 00:00:00
d.setTimeToNow(); // sets time to current time
d.toFormat(format); // returns date formatted with:
  // YYYY - Four digit year
  // MMMM - Full month name. ie January
  // MMM  - Short month name. ie Jan
  // MM   - Zero padded month ie 01
  // M    - Month ie 1
  // DDDD - Full day or week name ie Tuesday 
  // DDD  - Abbreviated day of the week ie Tue
  // DD   - Zero padded day ie 08
  // D    - Day ie 8
  // HH24 - Hours in 24 notation ie 18
  // HH   - Padded Hours ie 06
  // H    - Hours ie 6
  // MI   - Padded Minutes
  // SS   - Padded Seconds
  // PP   - AM or PM
  // P    - am or pm
d.toYMD(separator); // returns YYYY-MM-DD by default, separator changes delimiter

d.between(date1, date2); // true/false if the date/time is between date1 and date2
d.compareTo(date); // -1 if date is smaller than this, 0 if equal, 1 if date is larger than this
d.equals(date); // true/false, true if dates are equal
d.isBefore(date); // true/false, true if this is before date passed
d.isAfter(date); // true/false, true if this is after date passed
d.getDaysBetween(date); // returns number of full days between this and passed
d.getHoursBetween(date); // returns number of hours days between this and passed
d.getMinutesBetween(date); // returns number of full minutes between this and passed
d.getSecondsBetween(date); // returns number of full seconds between this and passed

d.add({ milliseconds: 30,
        minutes: 1,
        hours: 4,
        seconds: 30,
        days: 2,
        weeks: 1,
        months: 3,
        years: 2}); // adds time to existing time

d.addMilliseconds(number); // add milliseconds to existing time
d.addSeconds(number); // add seconds to existing time
d.addMinutes(number); // add minutes to existing time
d.addHours(number); // add hours to existing time
d.addDays(number); // add days to existing time
d.addWeeks(number); // add weeks to existing time

Answer 5

Or you could use the moment.js library to handle dates and format them accordingly to your needs

Answer 6

You can use moment.js

First, add moment to your express application locals

express = require('express');
...
app = express();
app.locals.moment = require('moment');

Then you can use moment within a jade template like this:

p #{moment(Date.now()).format('MM/DD/YYYY')}

Moment takes Date.now() by default, so yo can also write:

p #{moment().format('MM/DD/YYYY')}
