What is streamroller?

The streamroller npm package is a file-based logging utility designed to help manage log files by supporting automatic rolling of logs based on size or date. It is particularly useful for applications that generate a lot of log data and need to manage disk space efficiently.

What are streamroller's main functionalities?

Rolling file streams based on size

This feature allows you to create a log file that rolls over when it reaches a certain size. In the example, a new log file is created when the current log file reaches 10 MB. The '3' indicates that a maximum of three backup files are kept.

const StreamRoller = require('streamroller');
const stream = new StreamRoller.RollingFileStream('example.log', 1024 * 1024 * 10, 3);
stream.write('This is a log entry');
stream.end();

Rolling file streams based on date

This feature allows for log files to be rolled over based on date patterns. The 'yyyy-MM-dd' pattern means the log file will roll over daily. The 'daysToKeep' option specifies that logs older than 10 days should be deleted.

const StreamRoller = require('streamroller');
const stream = new StreamRoller.DateRollingFileStream('example.log', 'yyyy-MM-dd', { daysToKeep: 10 });
stream.write('This is a log entry');
stream.end();
