  • Compose the map onto the inner observable: switchMap(user => this.http.getUserData(user.id).pipe(map(res => { user.data = res.data; return user; }))) Commented Dec 23, 2019 at 0:54

This should do the trick for you.

this.users$ = this.http.getUsers(criteria).pipe(
  switchMap(user => this.http.getUserData(user.id).pipe(
          map((res) => ({...user, data: res.data}))
  )),
);
