Is it possible to use Angular signals instead of rxJS operators to handle API calls and responses effectively?

Is it feasible to substitute pipe, map, and observable from rxjs operators with Angular signals while efficiently managing API calls and their responses as needed?

I attempted to manage API call responses using signals but did not receive quick response times compared to rxjs operators. Managing it is somewhat challenging.

I am curious about your experiences with signals and the response time of modified data.

Answer №1

When making API calls, the return value is received asynchronously, meaning it takes some time to get the result.

In contrast, signals always have a value and operate synchronously. Even if you consider "undefined" as no value, signals cannot be used to generate asynchronous values.

For API calls, observables or promises are still necessary.

RxJS operators can manipulate when a new value should be emitted, but signals always have a set value and do not emit new values (they simply notify when the value changes) in a synchronous manner.

Due to this difference, RxJS operators cannot be replicated for use with signals.
