How to gracefully handle errors from HTTP requests in Angular?

For HTTP requests, use the `catchError()` operator to handle potential errors like network issues, server errors (e.g., 500 Internal Server Error), and invalid responses. Within `catchError()`, you can log the error, display an appropriate message to the user, or attempt to retry the request. Consider using Angular's `HttpErrorResponse` to access specific details about the HTTP error (e.g., status code, headers, body).
