Stream level changes the level of another stream

[lukassr]

Here's an example:

const pinoms = require('pino-multi-stream');
const fs = require('fs');

const logger = pinoms({
  level: 'silent',
  serializers: {
    err: pinoms.stdSerializers.err,
    req: pinoms.stdSerializers.req,
    res: pinoms.stdSerializers.res,
  },
  streams: [
    {
      stream: fs.createWriteStream('./test/info.debug.txt'),
      level: 'debug', 
    },
    {
      stream: fs.createWriteStream('./test/info.silent.txt'),
    },
  ],
});

logger.info('test');

It appears that the debug level in the child overwrites the silent level. If you run that code, you will see a log inside info.silent.txt. Also, if you check the level of logger it will be debug instead of silent.

I had to fix this putting the level in every child instead of the level in the parent.

Can you provide a full reproduction?

Are you looking for the dedupe option?

[lukassr]

Not really. dedupe will only log to the one stream with the higher level. What I'm looking is to have multiple streams, some of them sharing the same level defined in the parent but some others with specific level. In the example above, the second stream should have the silent level, because it is declare in the parent, but I think it not the case, because it will log anyways in the .txt. If you declare level:'silent' in the second stream, it will work as it should.

Thanks for the answers.
