Rotate and compress log files or directories for your node application on app start.
Copyright (C) 2017 Larry Price <larry.price.dev@gmail.com>. See LICENSE for more details.
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.
