moment-duration-format.d.ts Definition Not Extending Moment Module

Question

Any idea why this doesn’t work or how I can extend the duration interface to support the format function?

declare module \'moment\' {
     interface Duration         


        

Answer 1

You need to have the following dependencies installed:

"dependencies": {
  "@types/moment-duration-format": "2.2.2",
  "moment": "2.24.0",
  "moment-duration-format": "2.3.2"
}

If that's the case then you need these imports in the exact same order:

import * as moment from 'moment';
import 'moment-duration-format';

Afterwards you should be able to do this:

const seconds: number = Math.floor(process.uptime());
const formatted: string = moment.duration(seconds, 'seconds').format({
  precision: 0,
  template: 'y [years], w [weeks], d [days], h [hours], m [minutes], s [seconds]',
});
