How to use moment-duration-format in TypeScript?

rated 0 times [ 78] [ 6] / answers: 1 / hits: 21006 / 7 Years ago, tue, march 28, 2017, 12:00:00

I am using moment.js in my TypeScript (Ionic2/Angular2) project. Following on from this post, I now want to try out a plugin moment-duration-format

I have the npm package and the type definition and am able to use by import as..

import moment from 'moment';

...

let duration = moment.duration(decimalHours, 'hours');

I now want to use moment-duration-format

I have installed via npm install moment-duration-format --save and then the type definition via npm i @types/moment-duration-format --save.

I can see both npm modules.

As always, there is always some mystery on how to use such type definitions (the useage including import never seems to be in any doco).

I have tried adding import 'moment-duration-format';, import duration from 'moment-duration-format'; (moment-duration-format/index.d.ts' is not a module.)

I get an error when trying to use as follows..

let dd = moment.duration.format(400.99, 'hours').format('D:HH:mm');



// (TS error [ts] Property 'format' does not exist on type '(inp?: DurationInputArg1, unit?: DurationConstructor) => Duration'.

Does anyone have any idea on how to use this in TypeScript.

Thanks in advance

I was using the workaround here, but it now looks like the ype def has been fixed. Getting an update of the type def So I can do the following...

import * as moment from 'moment';

import 'moment-duration-format';



let duration = moment.duration(decimalHours, 'hours') ;   

let options : moment.DurationFormatSettings   = {

  forceLength : false,

  precision : 0,

  template : formatString,

  trim : false

};

let result  = duration.format(formatString, 0, options);
