Use Moment.js with angular2 application

Recently i was developing an application in angular2 where i had to use a calendar which shows the results for this month, this week and this weekend. I was finding a solution in pure javascript but it was time consuming. I decided to go on with moment.js , this is how i have embedded moment with angular2 application.

Step 1 : npm install moment --save

Step 2 : In your systemjs.config.js file's map array add:

'moment': 'node_modules/moment'

to packages array add:

'moment': { defaultExtension: 'js' }

Step 3 : In your component.ts use: import * as moment from 'moment/moment';

and that's it. Now you should be able to use moment with your application.

Example:
public setDate(term: string) {
    var status: string;
    status = term;
    switch (status) {
      case "today":
        this.fromDate = moment().toDate();
        break;
      case "tomorrow":
        this.fromDate =  moment(new Date()).add(1,'days').toDate();
        break;
      case "weekend":
        this.fromDate = moment().startOf('week').add('days', 6).toDate();;
        this.toDate = moment().startOf('week').add('days', 7).toDate();
        break;
      case "thisweek":
        this.fromDate = moment().startOf('week').toDate();;
        this.toDate = moment().startOf('week').add('days', 7).toDate();
        break;
      case "nextweek":
        this.fromDate = moment().startOf('week').add('days', 7).toDate();
        this.toDate = moment().startOf('week').add('days', 14).toDate();
        break;
      case "thismonth":
        var date = new Date(), y = date.getFullYear(), m = date.getMonth();
        var firstDay = new Date(y, m, 1);
        var lastDay = new Date(y, m + 1, 0);
        this.fromDate = moment(firstDay).toDate();
        this.toDate = moment(lastDay).toDate();
        break;
    }
