Answer 1

We can do like this also

var winston = require('winston');
const { createLogger, format, transports } = require('winston');
var config = require('../configurations/envconfig.js');

var loggerLevel = process.env.LOGGERLEVEL ||  config.get('LOGGERLEVEL');

var logger = winston.createLogger({
  format: format.combine(
    format.timestamp({
      format: 'YYYY-MM-DD HH:mm:ss'
    }),
    format.printf(info => `${info.timestamp} ${info.level}: ${info.message}`+(info.splat!==undefined?`${info.splat}`:" "))
  ),
  transports: [
    new (winston.transports.Console)({ level: loggerLevel }),
  ]
});
module.exports = logger;
