a wrapper module that I'm using to abstract the logger for use in other modules

log.js

// Require necessary modules
var path = require('path');
var log4js = require('log4js')();

// Define variables with module scope
var configPath = path.join( process.env.USWDSS_BWMCI_HOME, 'config');
var logConfigFile = path.join(configPath, 'log4js.json');

exports.getLogger = function (category) {
	log4js.configure(logConfigFile);
	return log4js.getLogger(category);
};
