Other information

There is this issue #10342 that is closed, but still there is no support for JSON string format.

We are in a need of JSON string logs - it's easier to parse in Google Cloud and there are less problems with newlines.

Some projects that handle this issue exists:

• https://github.com/igrek8/gc-json-logger-nestjs
• https://github.com/marciopd/json-logger-service
  but they doesn't seems to be updated. And I think a basic form of this functionality should be provided without external library.
