ngx-moment

moment.js pipes for Angular

This module works with Angular 5.0 and newer.

For an Angular 2 / 4 version, please install angular2-moment. For the AngularJS, please check out angular-moment.

Installation

npm install --save moment ngx-moment

or if you use yarn:

yarn add moment ngx-moment

For System.js users:

Don't forget to update your systemjs.config.js:

packages: {
            app: {
                main: './main.js',
                defaultExtension: 'js'
            },
            'moment': {
                main: './moment.js',
                defaultExtension: 'js'
            },
            'ngx-moment': {
                main: './index.js',
                defaultExtension: 'js'
            }
        }

Usage

Import MomentModule into your app's modules:

import { MomentModule } from 'ngx-moment';

@NgModule({
  imports: [
    MomentModule
  ]
})

This makes all the ngx-moment pipes available for use in your app components.

  `
})

Prints Last updated: 2012-03-17 16:55

amFromUtc pipe

Parses the date as UTC and enables mode for subsequent moment operations (such as displaying the time in UTC). This can be combined with amLocal to display a UTC date in local time.
