Trying to search trough extrnal api Weather servis.
Api is tested and works fine.
Problem: Enter value in search bar and main Search method from servis is not called. That is reason why request is not sent.
I follow tutorial from angular official documentation:
https://angular.io/tutorial/toh-pt6#search-by-name
And this not work.
Search Component:
export class SearchCityComponent implements OnInit {
cities$: Observable
private searchTerms = new Subject()
constructor(private weaterService: WeatherService) {}
// Push a search term into the observable stream.
search(term: string): void {
this.searchTerms.next(term)
}
ngOnInit(): void {
this.cities$ = this.searchTerms.pipe(
// wait 300ms after each keystroke before considering the term
debounceTime(300),
// ignore new term if same as previous term
distinctUntilChanged(),
// switch to new search observable each time the term changes
switchMap((term: string) => this.weaterService.searchCities(term))
)
}
}
Service:
/* GET cities whose name contains search term */
searchCities(term: string): Observable {
if (!term.trim()) {
return of([])
}
return this.http
.get(`${this.citiesUrl}/?query=${term}`, httpOptions)
.pipe(
tap(_ => this.log(`found cities matching "${term}"`)),
catchError(this.handleError("searchCities", []))
)
}
When I enter in search input some value:
In Search Comnponent in ngOnInit() last line of code is Not called search function from services?
switchMap((term: string) => this.weaterService.searchCities(term))
