Using Rollup for Angular 2's AoT compiler and importing Moment.js

Question

I\'m trying to follow the official AoT guide for Angular 2, and I\'m using Moment.js in my application. Moment.js is on my packages.json file, and I\'m using versio

Answer 1

Here is what I did to make work moment with typescript (at 2.1.6) and rollup (0.41.4).

1. To import moment, keep the standard way:

   import * as moment from 'moment';

import moment from 'moment'; is non-standard for a package without a default export, it will result an error at runtime: moment_1.default is not a function

2. In typescript use moment with by casting moment as any, and call the default function:

   var momentFunc = (moment as any).default ? (moment as any).default : moment;
   var newFormat = momentFunc(value).format( format );
   

moment(value).format(format) will result an error at rollup tree shaking: Cannot call a namespace ('moment')
