Winston Log Daily Roll

I have my log files rolling and appending with the correct date format. 

 foo.log.2014-10-02
 foo.log.2014-10-03

but I was wondering if I could create a situation where my most current log always had a consistent name. For example

foo.log
foo.log.2014-10-02
foo.log.2014-10-03

Here foo.log would represent the log for 10-04

or 

foo.log
foo.log.2014-10-02
foo.log.2014-10-03
foo.log.2014-10-04

Here foo.log would represent the log for 10-05

Solution

  • As far as I'm aware, you can't do this with the current implementation of the winston module. However, you could fork the module and edit the DailyRotateFile transport to implement this. All you'd need to do is rename the file that is currently used, and edit the file renaming when the file rolls over.
