Init a log4js logger with category auto-set to 'module' name, via base prototype.

base-with-log4js.js

module.exports = Base;
function Base(category) {
	try {
		category = category || new Error().stack.match(/Base\.(\w+)/)[1];
	} 
	finally {
		if (!category) {
			throw new Error('Base requires its sub-class to supply a logging-category argument! ');
		}
	}
	this.logger = require('./log4js').getLogger( category );
}

subclass.js

const Base = require('./base.js');
/*	@constructor */
function ASubClass() {
  Base.call(this);
}

/* @augments Base */
TestFramework.prototype = Object.create(Base.prototype);
