Angular: How to know if request has been cancelled in HttpClient

Question

To know if a request has completed, I do if (httpEvent instanceof HttpResponse). Likewise, how to know if a request is cancelled in HttpInterceptor

Answer 1

It seems like angular ignores the abort event. Here is the Angular sources: https://github.com/angular/angular/blob/5.0.1/packages/common/http/src/xhr.ts

The returned Observable does notifiy subscribers if the request is aborted.
