Date formats Plugins

This section discusses the following types of Date format plugins −

• Java dateformat parser
• Short date formatter
• Parse date format
• Duration format
• Date Range
• Precise Range

Java DateFormat Parser

You can use the following command to install it with Node.js −

You can get the moment-jdateformatparser.js from GitHub − https://github.com/MadMG/moment-jdateformatparser Observe the following working example for moment-jdateformatparser and MomentJS −

Example

var m = moment().formatWithJDF("dd.MM.yyyy");

Output

Short date formatter

The JavaScript file for shortdateformat can be fetched from GitHub −

https://github.com/researchgate/moment-shortformat

Syntax

The display looks like as shown in the table here −

You can take the script for momentshort from GitHub link given above.

Example

var a = moment().subtract(8, 'hours').short();
var b = moment().add(1, 'hour').short(true);

Output

If you want to remove the suffix ago or in, you can pass true to short(tru.

Parse date format

You can use the following command to install it with Node.js −

npm install moment-parseformat

Duration Format

You can use the following command to install duration format on Node.js −

The repository for duration format is available here − https://github.com/jsmreese/moment-duration-format Let us see a working example with duration format −

var a = moment.duration(969, "minutes").format("h:mm:ss");

Output

This adds more details to the duration on moment created.

Date Range

You can use the following command to install date range on Node.js −

npm install moment-range

Example

window['moment-range'].extendMoment(moment);
var start = new Date(2012, 0, 15);
var end = new Date(2012, 4, 23);
var range = moment.range(start, end);
console.log(range.start._d);
console.log(range.end._d);

Output

Precise Range

Precise range will display the exact date difference in date, time and in human readable format. You can use the following command to install precise range on Node.js −

npm install moment-precise-range-plugin

Example

var a = moment("1998-01-01 09:00:00").preciseDiff("2011-03-04 18:05:06");

Output
