IDoxTerminableMiddleware class abstract

A middleware that runs code after the answer is sent to the client, like the terminate of Laravel. Good for work the client should not wait for: logs, metrics, cleanup.

terminate gets the request and the answer that was sent. res.status is the status that was sent. An error in terminate is sent to ExceptionHandler.report. It never changes the answer.

A class can also implement IDoxMiddleware or IDoxNextMiddleware, to run code before the controller too.

class Metrics implements IDoxMiddleware, IDoxTerminableMiddleware {
  @override
  dynamic handle(IDoxRequest req) => req;

  @override
  void terminate(DoxRequest req, DoxResponse res) {
    print('${req.method} ${req.uri.path} ${res.status}');
  }
}
