As with any web application, Verdaccio has a customisable built-in logger. You can define multiple types of outputs.
|
|
|
|
```yaml
|
|
# console output
|
|
logs: { type: stdout, format: pretty, level: http }
|
|
```
|
|
|
|
or file output.
|
|
|
|
```yaml
|
|
# file output
|
|
logs: { type: file, path: verdaccio.log, level: info }
|
|
```
|

> Verdaccio 5 does not support rotation file anymore, [here more details](https://verdaccio.org/blog/2021/04/14/verdaccio-5-migration-guide#pinojs-is-the-new-logger).
|
|
|
|
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](https://github.com/trentm/node-bunyan#stream-type-rotating-file)
