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

First, install types:

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

Second, import them in your file:

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

Then you can use

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