How to use moment.js library in angular 2 typescript app?

I tried to use it with typescript bindings:

npm install moment --save
typings install moment --ambient -- save

test.ts:

import {moment} from 'moment/moment';

And without:

npm install moment --save

test.ts:

var moment = require('moment/moment');

But when I call moment.format(), I get an error.
Should be simple, can anybody provide a command line/import combination that would work?

Update April 2017:

As of version 2.13.0, Moment includes a typescript definition file. https://momentjs.com/docs/#/use-it/typescript/

Just install it with npm, in your console type

npm install --save moment

And then in your Angular app, import is as easy as this:

import * as moment from 'moment';

That's it, you get full Typescript support!

Bonus edit: To type a variable or property as Moment in Typescript you can do this e.g.:

let myMoment: moment.Moment = moment("someDate");
