@Component({
  selector: 'page-home',

})
export class HomePage {

  constructor(public navCtrl: NavController) {

  }
  testFun(){
    Contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

home.html

Answer 1

Since Ionic 3.xx, the way you use the Native plugin is slightly different from Ionic 2.xx

• First you need to add Contactto your constructor
• You need to add providers Contactto @Component

, home.ts :

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Contacts, Contact, ContactField, ContactName } from '@ionic-native/contacts';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html',
  providers: [Contacts]
})
export class HomePage {

  constructor(public navCtrl: NavController, private contacts: Contacts) {

  }

  testFun(){
    this.contacts.find(['*']).then((contacts)=>{
      alert(JSON.stringify(contacts[0]));
    })
  }
}

?

Contacts.prototype.find(['*'])
            .then((contacts)=>{
                alert(JSON.stringify(contacts[0]));
            })
            .catch((err) => {
                alert('Error ' + err);
});
