// create the base logger, based on winston
const myWinstonLogger = createLogger({
  level: process.env.NODE_ENV === "development" ? "debug" : "info",
  format: format.combine(
    format.timestamp({
      format: "YYYY-MM-DD HH:mm:ss",
    }),
    format.errors({ stack: true }),
    format.splat(),
    format.json()
  ),
  transports: [],
});

// console output
myWinstonLogger.add(
  new transports.Console({
    format: format.combine(format.colorize(), format.simple()),
  })
);

// reset, before we continue
log.reset();

// add middleware
