I'm currently working on making a request to the backend for a boolean value using observables, but I'm struggling to figure out the best approach between .map and .subscribe.
return this.http.put({url}, credentials, this.requestOptions)
.catch((error: any) => Observable.throw(error.message)).map((res...
The API call returns a boolean value.
@PutMapping("/url")
public Boolean api(@RequestBody Credentials credentials)
How can I retrieve that boolean value in TypeScript?
When using the angular httpClient, it's important to include a generic parameter in the .put(...) method. This parameter specifies the type of data that the observable returned will resolve to, ensuring type safety.
If you're experiencing issues, it could also be related to properly subscribing to the observable.
Keep in mind that the http.put method returns an Observable, meaning it won't execute unless it is subscribed to.
