pomelo-logger is a log4js wrapper for pomelo which provides some useful features.

npm install pomelo-logger

besides category, you can output prefix as you like in your log
prefix can be filename, serverId, serverType, host etc
to use this feature, you just pass prefix params to getLogger function

var logger = require('pomelo-logger').getLogger(category, prefix1, prefix2, ...);

log output msg will output with prefix ahead

when in debug environment, you may want to get the line number of the log
to use this feature, add this code

process.env.LOGGER_LINE = true;

in pomelo, you just configure the log4js file and set lineDebug for true

{
  "appenders": [
  ],

  "levels": {
  }, 

  "replaceConsole": true,

  "lineDebug": true
}

in raw message mode, your log message will be simply your messages, no prefix and color format strings
to use this feature, add this code

process.env.RAW_MESSAGE = true;

in pomelo, you just configure the log4js file and set rawMessage for true

{
  "appenders": [
  ],

  "levels": {
  }, 

  "replaceConsole": true,

  "rawMessage": true
}

in pomelo logger configuration file log4js.json, you can add reloadSecs option. The reloadSecs means reload logger configuration file every given time. For example

{
	"reloadSecs": 30
}

the above configuration means reload the configuration file every 30 seconds. You can dynamic change the logger level, but it does not support dynamiclly changing configuration of appenders.

log.js

var logger = require('pomelo-logger').getLogger('log', __filename, process.pid);

process.env.LOGGER_LINE = true;
logger.info('test1');
logger.warn('test2');
logger.error('test3');
