Keep same file name for log and rotate the file with timestamp

logger.txt

I’m using winston@3.3.3 and winston-daily-rotate-file@4.5.0 In my logger configuration I have the following.

var transportError = new (winston.transports.DailyRotateFile)({
  filename: HOME_DIR + '/logs/backend/error/error-%DATE%.log',
  datePattern: 'YYYY-MM-DD-HH',
  zippedArchive: false,
  maxSize: '50m',
  maxFiles: '14d',
  level: 'error',
  name: 'error',

  createSymlink: true,
  symlinkName: 'error.log',
  tailable: true,

  handleExceptions: true,
  json: true,
  colorize: false,
});

this is supposed to be like current log file should be error.log and when rotates it should get append with date format

even though I have mentioned createSymlink, tailable set to true symlinkName with ‘error.log’ my current log files are like this error-2021-02-01-13.log, error-2021-02-01-12.log

I don’t understand the symlink options. Why not have the current file without any date/number and just apply them after a rotation? That’s what I need and what I had used in other languages. IMHO the mentioned options over-complicate the usage.

I don’t want to config my elastic search to watch the file with pattern. I thing its very important to have the current file without any pattern
