"export 'DOCUMENT' was not found in '@angular/platform-browser'

Question

Happened while trying to upgrade IONIC app from version 3 to 4

Updated all plugins and modules to latest available, without any luck.

ERROR in ./node         


        

Answer 1

inside this "\node_modules\ionic-angular\module.js" && app.js file we can't change if we are changing manuvally it dosent take;

so i suggest BehaviorSubject of angular functionality we can get componet changing values in any other component

page.ts // component

import { BehaviorSubject } from 'rxjs';

public status = new BehaviorSubject('');
  currentStatus = this.status.asObservable()

; // write this code inside the export class services

changeStatus(status){
  console.log('current status from common services:',status)
  this.status.next(status); // pass value to public observable variable
  }

you can subscribe response in other componet
