Implementing real-time search functionality using API calls in Angular

Seeking guidance on implementing Typeahead for a global search feature in my app. When users type, it should call an API and display results in a drop-down menu. I am a beginner in Angular and Typescript, so any working examples with code would be greatly appreciated. Currently using Angular version 10.

Thank you for any assistance!

There are numerous libraries available for utilization.

  explore = (text$: Observable<string>) =>
    text$.pipe(
      debounceTime(300),
      distinctUntilChanged(),
      tap(() => this.discovering = true),
      switchMap(query =>
        this.tagService.exploreByTerm(this.category, query).pipe(
          tap(() => this.searchFailed = false),
          catchError(() => {
            this.searchFailed = true;
            return of([]);
          }))
      ),
      tap(() => this.discovering = false)
    )
<input class="form-control" [placeholder]="placeholder" [(ngModel)]="value" (ngModelChange)="adjust($event)" [ngbTypeahead]="explore" [readonly]="readonly">

Something akin to this example.
