As any web application, verdaccio has a customisable built-in logger. You can define multiple types of outputs.

logs:
  # console output
  - {type: stdout, format: pretty, level: http}
  # file output
  - {type: file, path: verdaccio.log, level: info}

Use SIGUSR2 to notify the application, the log-file was rotated and it needs to reopen it.
