Winston 3 console transport (and base transport) not working in the browser

Please tell us about your environment:

• winston version?
  • winston@2
  • winston@3
• node -v outputs: 8.11.1
• Operating System? macOS
• Language? JS, ES6+

What is the problem?

Am I right in thinking that Winston 3 is aiming to be compatible in Node and the browser? If so, the browser throws up on setImmediate, as it’s a native Node thing. Currently, setImmediate is recommended to use this within new transports, so I can’t quite see how this can work.

To re-produce:

Init somewhere:

import { createLogger, transports } from 'winston'

const consoleTransport = new transports.Console({ handleExceptions: true })

const logger = createLogger({
  transports: [ consoleTransport ]
})

export default logger

Import and use somewhere in client-side code:

import logger from './logger'
logger.info('message for the browser console')

What do you expect to happen instead?

The browser console to log out the message

Sorry if I’m missing something here!

@sneko I just installed setImmediate through npm: https://github.com/YuzuJS/setImmediate, then included it in my webpack bundle by importing it:

import 'setimmediate'

Then it’s patched and available globally, on the window object
