How to avoid the entire request being logged every time using pino?

I am new to nodejs and decided to use the pino logger in my application. Here is the code snippet showing how I am using it:

const expressPino = require('express-pino-logger');
const { LOGLEVEL } = require('../config.js');

// Constructs a Pino Instance
const logger = pino({
  level: LOGLEVEL || 'trace',
  prettyPrint: { levelFirst: true, colorize: true, ignore: 'pid' },
});
// Construct an express middleware using the above pino instance
const expressLogger = expressPino({ logger });

module.exports = { logger, expressLogger };

Now, every time I do req.log.debug(config['abc']), the entire request body gets logged, thus making the logs very cumbersome to read. For every such log statement, the output looks like this:

DEBUG [1610445271782] (on blserver-org1): sku=FIN01  Query String
req: {
  "id": 1,
  "method": "POST",
  "url": "/ifo_params?sku=FIN01",
  "headers": {
    "channel-name": "mychannel",
    "content-type": "application/json",
    "authorization": "Bearer eyJhbGciOiJSUzI1NiIsImtpZCI6IjVmOTcxMmEwODczMTcyMGQ2NmZkNGEyYTU5MmU0ZGZjMmI1ZGU1OTUiLCJ0eXAiOiJKV1QifQ.eyJvcmdJZCI6ImJ1eWVyMiIsImFkbWluIjp0cnVlLCJpc3MiOiJodHRwczovL3NlY3VyZXRva2VuLmdvb2dsZS5jb20vbWFya2V0c24tZGV2IiwiYXVkIjoibWFya2V0c24tZGV2IiwiYXV0aF90aW1lIjoxNjEwNDQ0ODU5LCJ1c2VyX2lkIjoibzBWZWl4VnJmZFJqbEdWZXlNS1p4Q052TkZSMiIsInN1YiI6Im8wVmVpeFZyZmRSamxHVmV5TUtaeENOdk5GUjIiLCJpYXQiOjE2MTA0NDQ4NTksImV4cCI6MTYxMDQ0ODQ1OSwiZW1haWwiOiJidXllcjJfYWRtaW5AbWFpbGluYXRvci5jb20iLCJlbWFpbF92ZXJpZmllZCI6ZmFsc2UsImZpcmViYXNlIjp7ImlkZW50aXRpZXMiOnsiZW1haWwiOlsiYnV5ZXIyX2FkbWluQG1haWxpbmF0b3IuY29tIl19LCJzaWduX2luX3Byb3ZpZGVyIjoicGFzc3dvcmQifX0.QlHxLrxcfxUmGK_Q193RdQSIBsoHly66CZDTWdRdyfZNAn-wH13el41ILnAj3YqVWgAFJY8u4BcFgZYePCujIO2gKFsM0WUs2M-a7CsMcDaWpqrQyVsfalRoYMDsk1DJypaevuKV8O4IbmdkgCbS8HmYO-dk99LRcwwYKs_vVnNBO4bTv5FFzMLh-DXrVfVBKk23Qem7JN5lX9UU6RZ-4WAVN-pN-TR5uRuF2koWjCoa90CKNhYOzKW1zeN904f1rCeuY0a4R4faFYMNAlkxslBpVSKaXCkSBXOSCjVykp611Ay6EQBkrpqbD1zHvv6eEfaaMyOzjlH3DzDye-vfMQ",

    "connection": "keep-alive",
    "content-length": "114"
  }
}

I tried changing the log levels but that doesn't help. Can someone please tell me how to tell pino to not log the entire request every time.

If you are using multiple targets in a separate thread, you can proceed as follows:

export default pino(
  {
    level: 'debug',
    redact: {
      paths: ['req', 'res'],
      remove: true,
    },
  },
  transport,
)

I did the same in Nest js with this approach:

pinoHttp: {
        autoLogging: false,
        transport: {
          target: 'pino-pretty',
          options: {
            singleLine: true,
          },
        },
      },

I was trying to do something similar. I wanted to log the whole request info in the automatic logs like request completed, but not when I am doing other logs in the application. All I had to do was pass the quietReqLogger: true to the pinoHttp options, it still keeps the reqId property, which can be used to track the other info if needed.

LoggerModule.forRoot({
    pinoHttp: {
        genReqId: () => randomUUID(),
        quietReqLogger: true,
    },
})

Add them to ignore key when constructing your Pino instance.Here:

// Constructs a Pino Instance
const logger = pino({
  level: LOGLEVEL || 'trace',
  prettyPrint: {
    levelFirst: true,
    colorize: true,
    ignore: 'pid,req,res',
  },
});

Take a look: https://github.com/pinojs/pino-pretty#options

I was able to do it using information in this bug report on pino-http

The gist is to override the serializer for the request by including the following configuration option when initializing pino

serializers: {
  req: (req) => ({
    id: req.id,
    method: req.method,
    url: req.url
  })
}

Of course you can add or remove additional fields from the req. You can also do the same thing with the response if you use the res property.

This is how I solved it.

export function getChildLogger(req: Request) {
const id = req.id;
const logger = pino({
    level: 'info',  // what ever log level is required here

})
return logger.child({ reqId: id })
}

Then use it like this

app.get("/", (req, res) => {    
const logger = getChildLogger(req);
logger.info("This is test log")
res.json({ status: "ok" })
});

May be not the best solution. But works :D
