In Books component in html i`ve :

```
<a 
  routerLink="/books/{{book.id}}" 
  class="btn btn-secondary btn-sm">
  <i class="fa fa-file"></i>
</a>

```

in app-routing :

```
{ path: 'book/:id', component: BookDetailComponent }

```

In URL i see an id from firebase, but the path provides me to :

```
{ path: '**' , component: NotfoundComponent },

```
