how to convert minutes to HH:mm with moment plugin

I have 2 timestamps and i already calculated the time difference in minutes with moment plugin. Now i want to convert the minutes to HH:mm.

var x = moment('10:00', 'HH:mm');
var y = moment('11:30', 'HH:mm');
var diff = y.diff(x, 'minutes'); // 90 
var convert = moment.duration(diff, "minutes").format('HH:mm');
alert(convert); // should give me 01:30 but does not work

What i am doing wrong?

Answer

Since you have not specified what is the error, I’m assuming you are leaving the dependencies required for duration method.

The moment-duration-format depends on moment, so you should require it before using it.

npm install moment moment-duration-format

Then either you can import the dependencies or require them.

import moment from "moment";
import "moment-duration-format";

 var moment = require("moment");
  require("moment-duration-format");
  var x = moment("10:00", "HH:mm");
  var y = moment("11:30", "HH:mm");
  var diff = y.diff(x, "minutes"); // 90
  var convert = moment.duration(diff, "minutes").format("HH:mm");
  alert(convert);

Note: require is a Node.JS function and doesn’t work in client side scripting without certain requirements. More info

Hope it helps Thanks
