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

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')}

MomentJs is a really big library. It's fantastic for comparisons and working with dates, but if you just want to display todays date you really don't need to include a library and can take a look at any of the pure JS answers.. – Nudnik

@Nudnik Yeah moment is quite big.. have a look at github.com/date-fns/date-fns – Overstrain

Answer 2

This is old, but I do the following:

return (new Date()).toLocaleDateString()

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

or (new Date()).getFullYear(); for the full year only (e.g. in the footer) – Chute

Is any options is available to change the format 'yyyy-mm-dd' – Kayseri

Answer 3

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

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.

You will need to use the methods on the Date object to achieve what you're after. See https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date

For example, the code below should do what you need:

var dateNow = new Date();
var dd = dateNow.getDate();
var monthSingleDigit = dateNow.getMonth() + 1,
    mm = monthSingleDigit < 10 ? '0' + monthSingleDigit : monthSingleDigit;
var yy = dateNow.getFullYear().toString().substr(2);

var formattedDate = mm + '/' + dd + '/' + yy;

So if you were using say jade with express and node you could do something like:

res.render('jadeTemplateName', { 
    dateNow: function() {
        var dateNow = new Date();
        var dd = dateNow.getDate();
        var monthSingleDigit = dateNow.getMonth() + 1,
            mm = monthSingleDigit < 10 ? '0' + monthSingleDigit : monthSingleDigit;
        var yy = dateNow.getFullYear().toString().substr(2);

        return (mm + '/' + dd + '/' + yy);
    } 
})

and in your jade template say if you wanted to add the date to a span:

span Today's date is #{dateNow()}

I dont see how i would put all that in jade #{ } – Colonial

Apologies I missed jade in the title. Answer corrected to include jade – Abstract

Answer 6

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 ;
                }

})

Answer 7

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)};
