Can anyone help me figure out why this code isn't working or provide guidance on how to enhance the duration interface to include support for the format function?
declare module 'moment' {
interface Duration {
format(template: string, precision?: string, settings?: any): string;
}
}
Example usage:
moment.duration(minutes, 'minutes').format('mm');
I'm encountering an error stating that 'format' is not recognized as a type within 'Duration'
To get started, begin by adding the necessary types:
npm install --save-dev @types/moment-duration-format
Next, remember to include them in your code:
/// <reference path='../..your-path.../node_modules/@types/moment-duration-format/index.d.ts' />
import * as moment from 'moment';
import 'moment-duration-format';
Once that's done, you can utilize:
moment.duration(minutes, 'minutes').format('mm');
Bring in:
import * as time from 'moment';
import 'duration-format';
When you are outside of your main function, create the following schemas:
interface Timeframe extends moment.Duration {
layout: (pattern?: string, precision?: number, options?: TimeframeOptions) => string;
}
interface TimeframeOptions {
adjustSize: boolean;
precision: number;
pattern: string;
tidyUp: boolean | 'left' | 'right';
}
Utilize this in your script:
const span = time.duration(minutes, 'minutes') as Timeframe;
return span.format('mm');
If your Timeframe schema is located in a separate document, make sure to export and import it accordingly.
Make sure to have the specified dependencies installed before proceeding:
"dependencies": {
"@types/moment-duration-format": "2.2.2",
"moment": "2.24.0",
"moment-duration-format": "2.3.2"
}
If you have all the necessary dependencies, ensure that you import them in the correct order as shown below:
import * as moment from 'moment';
import 'moment-duration-format';
Once you have completed the above steps, you will be able to execute the following code snippet successfully:
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]',
});
It's recommended to utilize namespace in place of module
declare namespace time {
interface Duration {
format(template: string, precision?: string, settings?: DurationSettings): string;
}
}
Additionally, ensure you have the correct settings for "time-duration-format": "^2.3.2"
interface DurationSettings {
trim: boolean | 'left' | 'right';
useGrouping: boolean;
usePlural: boolean;
useLeftUnits: boolean;
precision: number;
useSignificantDigits: boolean;
trunc: boolean;
forceLength: boolean;
minValue: number;
maxValue: number;
largest: number;
}
