Having trouble importing moment-range into your Angular 4.x application using ES6? Getting an error about incompatible call signatures?

In my Angular 4.x application, I encountered an issue while trying to import the moment-range package. The official documentation suggests using the following code:

import Moment from 'moment';
import { extendMoment } from 'moment-range';
const moment = extendMoment(Moment);

However, in my application, moment was added using a different method:

import * as Moment from 'moment';

Therefore, I attempted to apply the same approach to include moment-range:

import * as Moment from 'moment';
import * as MomentRange from 'moment-range';
const moment = MomentRange(Moment);

Unfortunately, this resulted in a TypeScript error. Can anyone provide guidance on resolving this issue?

Cannot invoke an expression whose type lacks a call signature. 
Type 'typeof "/node_modules/moment-range/dist/moment-range"' 
has no compatible call signatures.

Answer №1

Stumbled upon this code snippet on Github and gave it a try - pleasantly surprised that it worked flawlessly. Sharing here in case it proves helpful to someone else.

import * as moment from 'moment';
import { extendMoment } from 'moment-range';

const { range } = extendMoment(moment);

const dateRange = range(moment.utc([2016, 0, 1]), moment.utc([2016, 7, 1]));
