How to attach requestId to logger?

[nmichkarev]

Hi!
I have a question. We need to log an error information in ResultHandler with request id. Is it possible to define logger child for separate request with own metadata(requestId)? Or at least pass this requestId to ResultHandler?

Hello @nmichkarev ,

You can .addExpressMiddleware() with a package express-request-id (check it out) or similar. In this case the request would have the property id.

However, currently you might need also a custom ResultHandler, since the default one is not aware of such additional features, and moreover, the request id does not exist at the moment of logger creation.

In case you have any ideas on how it could be easily customizable, please let me know.

Regarding child loggers except the ResultHandler, the following approach can be used: #1465

The feature of childLoggerProvider is now available in recently released version 16.4.0 🚀
