For System.js users:

First you need to install moment:

npm install moment --save

Don´t forget to update your systemjs.config.js:

packages: {
            app: {
                main: './main.js',
                defaultExtension: 'js'
            },
            'moment': {
                main: './moment.js',
                defaultExtension: 'js'
            },
            'angular2-moment': {
                main: './index.js',
                defaultExtension: 'js'
            }
        }

Usage

Import MomentModule into your app's modules:
