Functions ¶
func InternalErrorMiddleware ¶
func InternalErrorMiddleware(logger log.Logger) endpoint.Middleware
InternalErrorMiddleware is a convenience middleware which can be used in combination with panics. After data is sanitized and validated, services can expect to get reasonable valid data passed (e.g. object not nil, string not empty, ...). With this middleware in place the service can throw an exception with a precond.PreconditionError as payload. This middleware will catch that and translate it into an application level PreconditionError. All other detected panics will be converted into an InternalServerError. In both cases it is most likely that there is an error withing the application or a library. Long story short, this is about failing early in non recoverable situations.
