Banner Error
A banner error shows an error as a Banner inside your view. Errors which package application/xerror
recognizes, e.g. a missing login, a denied permission, a missing element or a validation error, are shown with a localized, user-friendly text. For all other errors the user only
sees a generic text and a token, so that no confidential details leak; the error itself is logged with the same
token. It renders nothing if the error is nil, so you can place it unconditionally. To show the error as an overlay
instead, call alert.ShowBannerError, see Banner Messages.
err := fmt.Errorf("cannot connect to database: connection refused")
// the user only sees a generic message, the details go into the log
