I would suggest to rotate log based on size of the log file, using size you can do it as given below.

You can use logrotate-stream for this.

  1. Install it globally using npm install -g logrotate-stream

  2. Run your server using node app.js 2>&1 | logrotate-stream app.log --keep 5 --size '1m' --compress

Explanation

2>&1 send stderr to stdout (detail about 2>&1)

| pipe output(here stderr and stdout) to next command as input (here logrotate-stream)

app.log log file name

--keep 5 maximum number of file to keep

--size 1m maximum size of each file in mb --compmress compress files

Log files will look like this

app.log
app.log.0.gz
app.log.1.gz
app.log.2.gz
app.log.3.gz
app.log.4.gz

Such element of any program is called 'logger' . Logger can easily handle your log files.

There are a lot of implementation for logging of your server

You can find any logger either npm or github or even in Google;)

for example, npm install winston

https://github.com/winstonjs/winston

  var winston = require('winston');

  winston.log('info', 'Hello distributed log files!');
  winston.info('Hello again distributed logs');

  winston.level = 'debug';
  winston.log('debug', 'Now my debug messages are written to console!');
