Usage

The rotate function takes in two parameters, logname and backups, and returns a promise:

const logRotate = require('simple-logrotate')

// input parameters
const logname = '/tmp/myapp'; // Path to the original log file or directory
const backups = 3;            // Number of compressed backup logs to keep

logRotate(logname, backups).then(() => {
  // insert your main logic here
}, (err) => {
  // handle internal error
  console.error(err);
});

The backup files will be named as ${logname}.x.tar.gz, where x is an integer between 1 and backups. On rotation, the log corresponding with the integer x will be removed.
