Add support for reusing an existing winston logger instance

[ivansantosz]

Would be cool to be able to reuse an instance:

const logger = createLogger({
  format: format.combine(
    format.errors({ stack: true }),
    format.splat(),
    format.json()
  ),
  transports: [new transports.Console()],
});

Thank you for your reply!

You can simply pass logger as a parameter to the middleware

const consoleLogger = createLogger({
  format: format.combine(
    format.errors({ stack: true }),
    format.splat(),
    format.json(),
    format.prettyPrint(),
  ),
  transports: [new transports.Console()],
});
const middleware = logger({
  logger: consoleLogger,
});

Looking forward to your feedback
