this one helps. I couldn't find a way from the documentation.
But if you want to do, you can do this way:
logger.emitErrs = true;
logger.on('error', function (err) {
    // Check err contains msg for Elastic Search Log.
    // Add File Tansport.
    // Note* : Please check File Transport exist or not. If exists do not add second time

With these it helps It's caused by colors package (used by winston) that performs the following check when trying to determine whether to support colors:
if (process.stdout && !process.stdout.isTTY) {
    return false;
var colors = require('colors/safe');
colors.enabled = true; // add this line

I wish this help you You can use the logging event for that:
logger.on('logging', function(transport) {
  // check if this was the `File` transport
  if (transport.name === 'file') {
    console.log('logged a message to', transport.filename);

How to log node errors with winston logger?

Tag : javascript , By : kuba53280

Any of those help Winston can log exceptions for you. From the docs: Exceptions
const { createLogger, transports } = require('winston');

// Enable exception handling when you create your logger.
const logger = createLogger({
  transports: [
    new transports.File({ filename: 'combined.log' }) 
  exceptionHandlers: [
    new transports.File({ filename: 'exceptions.log' })

// Or enable it later on by adding a transport or using `.exceptions.handle`
const logger = createLogger({
  transports: [
    new transports.File({ filename: 'combined.log' }) 

// Call exceptions.handle with a transport to handle exceptions
  new transports.File({ filename: 'exceptions.log' })
