Logger

danger

Since v5.22.0 the logger property is renamed from logs to log, it is still backward compatible but displaying a warning

As with any web application, Verdaccio has a customizable built-in logger. You can define multiple types of outputs.

# console output
log: { type: stdout, format: pretty, level: http }

or file output.

# file output
log: { type: file, path: verdaccio.log, level: info }

Verdaccio 5 does not support rotation file anymore, here more details.

Use SIGUSR2 to notify the application, the log-file was rotated and it needs to reopen it. Note: Rotating log stream is not supported in cluster mode. See here
