How to configure logging output in json format?

Hello Guys,

Please help us understand how to configure log output in json format or how to integrate JSreport logs with Kibana?

jsreport uses the winston logging package so pretty much everything you find out in the winston docs can be applied in the jsreport.
https://jsreport.net/learn/configuration#logging

To enable json for all transports, add a default logging config to jsreport.config.json.

 "logger": {
    "console": {
      "transport": "console",
      "level": "debug"
    },
    "file": {
      "transport": "file",
      "level": "debug",
      "filename": "logs/log.txt"
    },
    "error": {
      "transport": "file",
      "level": "error",
      "filename": "logs/error.txt"
    }
  },

And the update the app server.js file with the following. It will instruct all transports to format in json.

const jsreport = require('jsreport')()

if (process.env.JSREPORT_CLI) {
  // export jsreport instance to make it possible to use jsreport-cli
  module.exports = jsreport
} else {
  jsreport.afterConfigLoaded(() => {
    const winston = require('winston')
    jsreport.logger.format = require('winston').format.combine(
      jsreport.logger.format,
      winston.format.json()
    )
  })
  jsreport.init().then(() => {
    // running
  }).catch((e) => {
    // error during startup
    console.error(e.stack)
    process.exit(1)
  })
}
