A logger config using winston

logger.js

const path = require('path')
const winston = require('winston')

const LOG_DIR = path.join(path.dirname(path.dirname(__filename)), 'logs')

const consoleLogFormat = winston.format.combine(
  winston.format.timestamp({format: 'DD/MM/YYYY HH:mm:ss'}),
  winston.format.colorize(),
  winston.format.printf(({level, message, label, timestamp}) => {
    return `${timestamp} ${label ? `[${label}] ` : ''}${level}: ${message}`;
  }))

const fileLogFormat = winston.format.combine(

  winston.format.printf(({level, message, label, timestamp}) => {
    return `${timestamp} ${label ? `[${label}] ` : ''}${level}: ${message}`;
  }))


const getLogger = (filePath) => {
  const fileName = path.basename(filePath).split('.').at(0)
  return winston.createLogger({
    level: 'debug',
    format: winston.format.simple(),
