As any web application, verdaccio has a customisable built-in logger. You can define multiple types of outputs.
|
||
|
|
|
||
|
|
<div id="codefund">''</div>
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
logs:
|
||
|
|
# console output
|
||
|
|
- {type: stdout, format: pretty, level: http}
|
||
|
|
# file output
|
||
|
|
- {type: file, path: verdaccio.log, level: info}
|
||
|
|
# Rotating log stream. Options are passed directly to bunyan. See: https://github.com/trentm/node-bunyan#stream-type-rotating-file
|
||
|
|
- {type: rotating-file, format: json, path: /path/to/log.jsonl, level: http, options: {period: 1d}}
|
||
|
|
```
|
||
|
|
|
||
|
|
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)
