[QUESTION] Log level when using as NestJS app logger about nestjs-pino HOT 4 CLOSED

You can specify log levels via configuration of LoggerModule: https://github.com/iamolegga/nestjs-pino#asynchronous-configuration please see https://github.com/iamolegga/nestjs-pino#configuration-params for more details

from nestjs-pino.

Is it level or useLevel?

From https://github.com/iamolegga/nestjs-pino#asynchronous-configuration

         pinoHttp: { level: config.level },

From https://github.com/pinojs/pino-http#pinohttpopts-stream

...
useLevel: the logger level pino-http is using to log out the response. default: info
...

from nestjs-pino.

@dlecan this two different options

useLevel: the logger level pino-http is using to log out the response. default: info

level sets level for logger, so only logs with level >= options.level will be emitted. I recommend read the docs of pino first

from nestjs-pino.

Also worth noting, the NestJS repl uses its own logger, so the pino logging config does not seem to be used (and hence any logger that might have been specified in that config.)
