crafity-logging module bridges a configurable crafity web application infrastructure to logging procedures. At the moment log4js module is used underneath except for minor changes that are wrapped up in crafity-log4js module. See crafity-log4js for more information.

Require logging module and and ask for a logger:

var logging = require('../main.js')
    , logger = logging.create([name], [category], config)
    ;
  • name String A name for the logger
  • category String A category for the logger
  • config Object An object literal with configuration

The following configuration example describes a logger with one console appender and one file appender:

{                                                       
    "keep": false, // drop default appenders   
    "appenders": [                                                    
        {                                                                
            "type": "console",                                              
            "category": "unittest",
            "name": "crafity-logging-to-console"
        },                                                               
        {                                                                
            "type": "file",                                                 
            "filename": "~/logs/app.log",                      
            "maxLogSize": 20971520,                                         
            "backups": 100,
            "category": "unittest"
            "name": "crafity-logging-to-file",                                  
        }                                                                
    ]
}                                                                                                                                                                                             
  • type: file - this tells log4js to use the file appender
  • type: console - this tells log4js to use the console appender
  • category: ... - if omitted in the configuration, it can be passed as an argument in create method and this will hold for all logger appenders.
  • keep: false - forget the default appenders on initialization
