``I would like to discuss the use of TypeScript in returning a boolean value from

I am new to Angular and Typescript, and I need help returning a boolean value from a function that I can use in *ngIf. I want this process to be seamless. Can someone assist me with this?

canView = false;

getView() {
    this.permissionService.getPermissionChecker('can_view_site', 'can_view_site').pipe(
      tap(res => {
        this.canView = true;
    );
  }

On the template side

<app-site compact=true *ngIf="canView"></app-site>

Answer №1

To obtain the Observable, simply call getView() and then utilize the async pipe within an ngIf statement.

getView(): Observable<boolean> {
     return this.permissionService.getPermissionChecker('can_view_site', 'can_view_site')
           .pipe(map(res => true (or false));
}

<div *ngIf="myObservable | async as myBoolean"></div>
