I have an iso-8601 duration which is as follows:

PT15M51S

I want to convert the duration into seconds so that I can store it in the db and order by duration etc.

Here is what I tried so far:

var moment = require('moment');
var duration = 'PT15M51S';
var x = moment(duration, moment.ISO_8601);
console.log(x.seconds());

Which results in NaN.

• 1 momentjs is huge. If you are only converting the value, use this instead: npmjs./package/iso8601-duration – Jonathan Commented Mar 23, 2018 at 18:19

You need to use moment.duration function. Also, to get the total value in seconds, use asSeconds() instead of seconds().

In your case:

var moment = require('moment');
var duration = 'PT15M51S';
var x = moment.duration(duration, moment.ISO_8601);
console.log(x.asSeconds()); // => 951
