moment is giving me error in angular 5 html template

Question

I am using moment v2.22.0 in angular 5, and this is how I have imported it in module -

import * as moment from 'moment';

and using it in component as -

export class ChatComponent {
  .
  .
  .
  public moment: any = moment;
  .
  .
}

and when I am using it in html template -

<div>{{moment(activeTeam.createdAt).format('LL')}}</div>

it is giving me an error message that -

[Angular] Member 'moment' is not callable

can anyone tell me what I am doing wrong !!

Answer 1

cli (run in console)

// install moment js
npm install moment --save

component declaration (ts)

// import and declare moment
import * as moment from 'moment';
moment: any = moment;

template file (html)

// template syntax
<p>{{moment(date_time_variable).format('ll')}}</p>

Thanks for the answer. Is there any advantage/ disadvantage of using moment directly in HTML rather than .ts file. – Triplett

Answer 2

Don't use any, declare without it

import * as moment from 'moment';
moment = moment;

Thanks for the answer. Any particular reason for not using any. – Triplett

Answer 3

Try to import moment as :

import  moment from 'moment';

HTML:

<div>{{getFormat(activeTeam)}}</div>

TS:

getFormat(activeTeam){
   return moment(activeTeam.createdAt).format('LL')
}

Thanks for the answer. Will there be any performance issue if a similar code is used with ngFor. – Triplett

Answer 4

Instead of declaring moment's type as any, declare it as moment: () => any;
