feat!: replace bunyan by pino.js

[juanpicado]

Reference #1760

Verdaccio replaces Bunyan by Pino.js as logger, with the objective to improve the performance and delegate some features to the external tools.

Breaking Changes

Logger configuration does not support multiple streams, thus the configuration must contain one single object.

Pretty loggin

Verdaccio logging pretty print is expensive in and not recommended to production environment, thus if the NODE_ENV=production is detected, will fall back to json format.

Multiple streams

Even if is supported by Pino.js is not recommended for performance reasons. The log property only recognize one single option. If you were using this feature and want it back, feel free to open a discussion or contribute as opt-in feature.

logs:  {type: stdout, format: pretty, level: http}

Rotating file is not longer supported

Pino.js does not support log rotation, thus if you were using this feature is recommended use an external tool.

 // this is not longer valid
 {type: rotating-file, format: json, path: /path/to/log.jsonl, level: http, options: {period: 1d}}

Deprecation

Old configuration won't crash the application, it will display a deprecation warning and will use the very first option in your configuration as fallback. Consider update your configuration due in the next major will throw an error.
