how to create symlink

[zhongshanxian]

i use rotating-file-stream to rotate log. After rotate, test.json.log will empty.
now I need that test.json.log save 7d log data, how can i do?
like winston.transports.DailyRotateFile createSymlink and symlinkName

const rotatingFileStream = require('rotating-file-stream');
const { createStream } = rotatingFileStream;

const pad = (num) => (num > 9 ? '' : '0') + num;
const generator = (time) => {
if (!time) return 'test.json.log';
const year = time.getFullYear();
const month = pad(time.getMonth() + 1);
const day = pad(time.getDate());
return test-${year}-${month}-${day}.json.log;
};

const stream = createStream(generator, {
path: './', // Specifies the base path for files
interval: '1d', // Specifies the time interval to rotate the file
maxSize: '200M', // Specifies the maximum size of rotated files to keep
maxFiles: 7 // Specifies the maximum number of rotated files to keep
});

Hi @zhongshanxian ,

ATM there is no option to create a symlink; I could take the occasion to add this feature, but in this period I'm so busy, it's possible I'm not able to start working on it in the next two weeks.

I'm sorry I'm not sure I got the point of the first two lines of the request; could it be that interval: '7d' is what you are looking for? If that's not the case, please feel free to ask.

emmmm, I had hoped not to empty the test.json.log after rotating. And provide an option to specifies the maximum days of test.json.log to keep.
I'd like to confirm that test.json.log similar winston.transports.DailyRotateFile createSymlink and symlinkName?

No sorry, at the moment there are not option to behave like that.

I can add this in the todo list, but as I said it will not be added soon.

Hope this helps,
