如何在TypeScript中使用矩持续时间格式? [英] How to use moment-duration-format in TypeScript?

问题描述

我在TypeScript(Ionic2/Angular2)项目中使用moment.js.从帖子，我现在想尝试一个插件 moment-duration-format

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

我有npm包和类型定义，并且可以通过import as使用.

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');

我现在要使用瞬间-持续时间格式

我已经通过npm install moment-duration-format --save安装了，然后通过npm i @types/moment-duration-format --save进行了类型定义.

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

我可以看到两个npm模块.

I can see both npm modules.

一如既往，如何使用此类类型定义始终存在一些谜团(包括import在内的用法似乎从未出现在任何doco中).

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).

我尝试添加import 'moment-duration-format';，import duration from 'moment-duration-format';(一刻持续时间格式/index.d.ts'不是模块.)

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

尝试使用以下方法时出现错误.

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'.

有人对在 TypeScript 中如何使用它有任何想法.

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

我正在使用

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);
