Ngx Moment

Ngx Moment is a library that helps to work with dates and times in Angular, using the popular Moment.js library.

Features

Ngx Moment provides the following features:

• Pipes to format dates and times in various formats
• Directives to display relative times and time ago strings
• Services to work with Moment.js objects and perform various calculations

Installation

To use Ngx Moment in your Angular project, you need to install it using npm:

npm install --save ngx-moment moment

After installing Ngx Moment and Moment.js, you need to import the NgxMomentModule in your app module:

import { NgxMomentModule } from 'ngx-moment';

@NgModule({
  imports: [
    // ...
    NgxMomentModule,
  ],
  // ...
})
export class AppModule { }

Usage

Pipes

Ngx Moment provides several pipes to format dates and times:

• amTimeAgo - displays a time ago string for a given date
• amDateFormat - formats a date
• amTimeFormat - formats a time
• amUtc - converts a date to UTC format

Here is an example of how to use the amDateFormat pipe:

<p>{{ '2022-05-28T12:00:00Z' | amDateFormat:'LL' }}</p>

This will output the date in the format May 28, 2022.

Directives

Ngx Moment also provides directives to display relative times and time ago strings:

• amTimeAgo - displays a time ago string for a given date
• amCalendar - displays a calendar string for a given date

Here is an example of how to use the amTimeAgo directive:

<p amTimeAgo="2022-05-28T12:00:00Z"></p>

This will output a time ago string, such as 2 hours ago.

Services

Ngx Moment also provides services to work with Moment.js objects and perform various calculations:

• MomentService - provides access to the Moment.js library and methods for creating and manipulating Moment.js objects
• DurationService - provides methods for working with time durations
• TimezoneService - provides methods for working with timezones

Here is an example of how to use the MomentService to create a Moment.js object:

import { MomentService } from 'ngx-moment';

constructor(private momentService: MomentService) {}

ngOnInit(): void {
  const date = this.momentService.create('2022-05-28T12:00:00Z');
  console.log(date.format('LL')); // 'May 28, 2022'
}

Conclusion

Ngx Moment is a useful library for working with dates and times in Angular, providing pipes, directives, and services to format, display, and manipulate dates and times.
