Log Rotation in Node.js?

Question

In my web analytics, I am logging the data in plan text file. I want to rotate the log on daily basis because its logging too much data. Currently i am using bunyan to rotate the logs.

Problem facing

Its rotating the file correctly, but rotated log file are in the name

log.0

,

log.1

, etc. I want the file name to be

log.05-08-2013

,

log.04-08-2013

Known
I can't able to edit the bunyan file to meet my requirement . Becoz we are installing the modules using

package.json

So my question is

Is there any other log rotation in node.js meets my requirement?

Answer 1

Winston does support log rotation using a date in the file name. Take a look at this pull request which adds the feature and was merged four months ago. Unfortunately the documentation isn't listed on the site, but there is another pull request pending to fix that. Based on that documentation, and the tests for the log rotation features, you should be able to just add it as a new Transport to enable the log rotation functionality. Something like the following:

winston.add(winston.transports.DailyRotateFile, {
  filename: './logs/my.log',
  datePattern: '.dd-MM-yyyy'
});
