What firebase and angularfire2 version

Angular
1

Because the npm firebase and angularfire2 packages have drastic changes I would like to use the versions used in the course for the duration of the course.

The issue is that this part is edited out of the video.

Does anyone here know which versions were used?

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 ā€˜Building Real-time Apps with Firebase : chapter 6ā€™.
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(ā€™/coursesā€™).valueChanges()
.subscribe(courses => {
this.courses = courses;
console.log(this.courses);
})
}

and in app.component.html :

< ul>
< li *ngFor=ā€œlet course of coursesā€>
{{ course }}
< /li>
< ul>

to get the same result as Mosh.
