Показать описание
So far we have always assumed that the HTTP request which we are going to make from angular application is always going to succeed. But what if there is an error. An HTTP request can return an error in many cases. For example, when there is no internet connection or server is down etc.

In such scenario's we should handle the error returned and show a meaningful error message to the end user. In this lecture, you are going to learn different ways in which you can handle HTTP error responses.

If we have subscribed inside the service, instead of using the subject, can we call the error function inside the subscriber, assign the value to a variable and call that variable inside the component file?

I am not sure you are using angular 13. errorMessage: string = null is not possilbe. It must be errorMessage : string | null = null. Further the subscribe is depricated as shown already in the ide. It is possible but not the correct way.
