I am having difficulty grasping some of the concepts. Such as I have
created a subscription to my SQL DB (users) upon login and I am able to
present the data on the page (DOM). However, I a now trying to pull out
specific data from the item to save for later use in my typescript file.
*login.component.ts*
this.usersService.getUsers() .subscribe((result: users) => (this.users[0] =
result));
*users.service.ts*
public getUsers() : Observable<user[]> {
let userEmail = sessionStorage.getItem('userEmail');
return this.http.get<user
[]>(`${environment.apiUrl}/${this.url}/${userEmail}`).pipe(
tap((res:any)=>{
sessionStorage.setItem('userRole', res.userRole;
})
);
This returns as expected and fills the following html.
*login.component.html*
<div class="row" style="background-color:transparent;"> <mat-card
*ngFor="let user of user" class="ecard">
<mat-card-title>{{user.role}}</mat-card-title> </mat-card> </div>
However, I would like to use information from the 'user' to perform other
functions in the ts file.
The TAP function is returning undefined and I do not understand why or how
to correct this?
