NodeJS winston log file not change upon size limit

Question

I'm using Winston logging and have specified file size to be max 10MB.

{
    filename: 'e:\app.log', 
    json:false, 
    maxsize:'10MB', 
    maxFiles:'10', 
    timestamp:true, 
    level:'silly'
}

I'm expecting the app.log file to be rotated upon size reaching 10MB, but this has never happened and my log file grows to even GBs.

Is there something I'm doing wrongly?　Thanks.

looks like you might need to either pass an absolute path for the `filename` or set a `dirname` according to this somewhat old [github issue](https://github.com/flatiron/winston/issues/90). — go-oleg, Jul 30 '14 at 06:00
Go-oleg, thanks. In fact, in my code, it is absolute path. Re-updated my question. — Lee, Jul 30 '14 at 06:02
I believe the value for `maxsize` should be in bytes, so you could try `10000000` instead of `'10MB'`. — go-oleg, Jul 30 '14 at 06:04

As you can see here the maxsize must be in bytes so change it for 10000000

the file is not rotating after reach the 'maxsize'. I'm using "winston": "^2.3.1" Any suggestions are appreciated. – Ketav Jan 29 '19 at 11:35

Use maxSize instead of maxsize it will work.

Thx, I tried, but the property only applies on File Size, the entry (message) size could be greater than it. – Luis Roberto Dec 09 '20 at 00:20
@Varun even when i add maxSize the log file is going way behind the size. I am giving 100MB but the files are exceeding 200Mb . – Mithiridi Prasanth Apr 22 '21 at 11:25

I think maxSize applies only for the file.

But before write inside it the Log Entry Size could be greater than the limit.

My question is if there are something similar like maxEntrySize to limit the log entry size directly, not only file size.
