What firebase and angularfire2 version

Angular
2

i have done trial and error for hours.
the version that works for me is :

  • angular : 4
  • firebase : 4.13.1
  • angularfire2 : 5.0.0-rc.3

even then i got an error in section ‘Building Real-time Apps with Firebase : chapter 6’.
in the video it is explained that AngularFireDatabase returns observable type, but for me it actually returns AngularFireList type.

So i adjust the code a bit in app.component.ts :

constructor(db: AngularFireDatabase) {
db.list(’/courses’).valueChanges()
.subscribe(courses => {
this.courses = courses;
console.log(this.courses);
})
}

and in app.component.html :

< ul>
< li *ngFor=“let course of courses”>
{{ course }}
< /li>
< ul>

to get the same result as Mosh.
