httperr 
HTTP error wrapper that returns an error if the HTTP request failed (i.e. 404, 500, etc.) as well as if any network issues occurred.
This is useful for cases when you don't care why an HTTP request failed, and would like to treat network errors and API errors once.
Usage
req, err := http.NewRequest(http.MethodGet, "/path", nil)
if err != nil {
return errors.Wrap(err, "new request")
}
resp, err := httperr.Check(client.Do(req))
if err != nil {
return errors.Wrap(err, "HTTP error")
}
defer resp.Body.Close()
// use resp
