Angular is introducing a new signals primitive in v19: resource. It will allow loading asynchronous data, e.g. from an HTTP request, in a declarative way with just signals. Not only that, it will also provide convenient access to signals representing the state of the request and any errors.

The PR: github.com/angular/angular/pull/58255
