Lightweight NodeJS Logging Overview

Unlike many of the libraries out there, Scribe.js allows logging on multiple files and is divided into folders by date. And it is possibly the easiest logging you can implement. And it does everything you need a basic logger to do.

• Save messages into log files organized by user, date, and type
• Print messages into console using colors indicating level of importance

Output Methods (Web | Console | File)

Method#Web - Select Date

Method#Web - Select Log Type

Method#Web - View Logs

Method#Console - Command Prompt

Method#File - File

Method#File - Directory Layout

// Configuration
// --------------
scribe.configure(function(){
    scribe.set('app', 'MY_APP_NAME');                     // NOTE Best way learn about these settings is
    scribe.set('logPath', './logs'); // Doublecheck       // them out for yourself.
    scribe.set('defaultTag', 'DEFAULT_TAG');
    scribe.set('divider', ':::');
    scribe.set('identation', 5);                          // Identation before console messages
    
    scribe.set('maxTagLength', 30);                       // Any tags that have a length greather than
                                                          // 30 characters will be ignored
    
    scribe.set('mainUser', 'root');                       // Username of the account which is running
                                                          // the NodeJS server

// Create Loggers
// --------------
