[Bug]: Typescript - info() is not a function #2348

🔎 Search Terms

typescript,info,logger

The problem

README.md is clear that the following syntax is legal:

logger.info('Hello world')

However I cannot get this to work with Typescript.

Versions:

Winston version: 3.10.0
Node version: v20.5.1

Example:

Using "esModuleInterop": true in tsconfig.json to allow the use of Winston using import syntax:

import { Logger, transports, format } from 'winston'
const logger = new Logger({
  level: 'debug',
  transports: [new transports.Console()],
  format: format.combine(format.splat(), format.colorize({ all: true }), format.simple())
})

logger.info('Hello world')

export default logger

Expected:

Console output of: Hello world

Actual:

logger_1.default.info is not a function

What version of Winston presents the issue?

3.10.0

What version of Node are you using?

20.5.1

If this worked in a previous version of Winston, which was it?
