Answer 1

Try the next:

export class AppComponent {
  countries: any[];

  constructor(db: AngularFireDatabase )
  {
      this.countries = db.list('/Country/countries').valuesChanges();
  }
}

And if you have a model then:

export class AppComponent {
  countries: Country[];

  constructor(db: AngularFireDatabase )
  {
     this.countries = db.list('/Country/countries').valueChanges();
  }
}
