I don't need a Subject. I was a little confused. I forgot about using the
return statement inside the map operator.
I kept wanting to assign the response body to a variable. This little bit
of code did the trick:
tap((response: HttpResponse<Member[]>) => {
this.totalCount =
JSON.parse(response.headers.get('X-Pagination')).totalCount;
}),
map((response: HttpResponse<Member[]>) => {
return response.body;
}),
I'm still wrapping my head around Angular :)
Thanks for your help.
