    Retry Failed Requests with RxJS and the HttpClient in Angular

    When the communication with the backend fails, before giving the user a negative response, it might be worth trying to automatically recover from the error. In some cases, that can be as simple as retrying to issue the request again. Since the Angular HttpClient heavily relies on RxJS we can apply some of its operators to make this happen, such as retry, retryWhen and delay.
