moment format is not a function

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 {
       format(template: string, precision?: string, settings?: any): string;
     }

}

when used as:

moment.duration(minutes, 'minutes').format('mm');

I’m getting the error that ‘format' does not exist on type ‘Duration'

Imports:

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

Outside of your class, define the interfaces:

interface Duration extends moment.Duration {
  format: (template?: string, precision?: number, settings?: DurationSettings) => string;
}

interface DurationSettings {
  forceLength: boolean;
  precision: number;
  template: string;
  trim: boolean | 'left' | 'right';
}

Then in your code:

const duration = moment.duration(minutes, 'minutes') as Duration;
return duration.format('mm');

If you defined your Duration interface in another file, you will need to export and import it as well.

How to use moment-duration-format in an Angular2 app ? � Issue , Hi, I'm struggling to use moment-duration-format in an angular2 app (with Wouldn't work via npm because it's not published, but did you try using Import it into your app, e.g. at the top of your main module, so that it is Or add their reference in a *.d.ts file: export interface IDuration extends moment. The problem is as R_B_ correctly worked out a wrong type definition in the typings module for moment-duration-format. I'll create a new pull request for this, as my last was closed because of lint errors.

First, install types:

npm install --save-dev @types/moment-duration-format

Second, import them in your file:

/// <reference path='../..your-path.../node_modules/@types/moment-duration-format/index.d.ts' />
import * as moment from 'moment';
import 'moment-duration-format';

Then you can use

moment.duration(minutes, 'minutes').format('mm');

moment-duration-format, Imports: import * as moment from 'moment'; import 'moment-duration-format';. Outside of your class, define the interfaces: interface Duration extends moment. Check if a moment is before another moment. The first argument will be parsed as a moment, if not already so. moment('2010-10-20').isBefore('2010-10-21'); // true If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.

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]',
});

  • I'm still getting errors in my code. Property 'duration' does not exist on type 'typeof 'moment''.
  • I'd need to have a look at your code to better understand where your error comes from. But do have a look at my answer, I updated the interface definitions. I don't think it will solve your problem, but once fixed, it will provide better autocomplete.
  • Works like a charm! Thanks
  • npm install --save-dev @types/moment-duration-format solved my problem, while npm install moment-duration-format didn't.
