Rxjs toPromise() deprecated

Question

I have read that toPromise() is being deprecated in RxJS 7 and will be removed in RxJS 8. I have often used it with async await syntax in angular to handle http calls. Is it considered an anti pattern? I understand the concept of streams but an http call only emit a single value. I don't get the point of observable for a simple http call. What should I use next? should I fully embrace reactive programming?

Answer 1

firstValueFrom and lastValueFrom is definitly a better alternative for many reasons:

1. The naming is more readable and self explanatory.
2. The additional ability to select either first or last value.
3. The additional ability to declare a default value in case the observable didn't emit any value at all like so await lastValueFrom(data$, {defaultValue: 'Some default value'})
