Date pipe, RC1 Android webview

Ionic Framework ionic-v3
1

Hello,

i wouldlike to use date pipe as follow:
{{created_at | date: 'dd/MM/yyyy à HH:mm:ss' }}

With ionic serve all is ok in the browser (chrome, firefox). But when i launch the android emulator (marshmallow) the date pipe cause error:
Cannot convert undefined or null to object (polyfills.js)

Same issue here. Before RC, I added the following line to index.html

<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=Intl.~locale.en"></script>

but that no longer works with RC1. Can someone help me or point me to docs for loading external js files in RC.

Thanks

if you search the GitHub of Ionic and Ionic app-scripts I think you will still find some issue which are open or closed about that. I think it’s still not 100% resolve.

I had the same issue, invested time, went mad, finished by creating my own pipes using momentjs

I’m having same problem with iOS emulator. I’m doing a simple {{value|date}} and works fine with serve and in emulator it gives me:

2     322277   error    EXCEPTION: null is not an object (evaluating 'new Intl.DateTimeFormat(e,n)')

I guess I’ll create my own moment.js pipe for now :confused:

Same problem over here using a real android device. Simple date pipe {{ value | date }} working fine with serve an error on device:

TypeError: Cannot convert undefined or null to object
    at new DateTimeFormat (native)

Exact same error here, guess I’ll try writing a custom pipe…

By now, I’m using angular2-moment, moment.js pipes for Angular2

@reedrichards can you please share your pipe code ?

Actually I did a component not a pipe. Something like

ts:

 import {Component, Input} from '@angular/core';
 import moment from 'moment';

@Component({
templateUrl: 'display-date.html',
selector: 'display-date'
})
export class DisplayDateDirective {

  @Input() displayDate:Date;

   getFormattedDate():string {
      return this.displayDate != null ? moment(this.displayDate).format('ll') : '';
   }
 }

html:

<span>{{getFormattedDate()}}</span>
