Ultimate-logger is a extension to javascript console.log. Features:

• adds info about moduleName/methodName/lineNumber to the console.log printout
• simple filtering(i.e. you can include/exclude console.log printouts from modules/methods)
• custom console.log printout format

It simply allows you to have

//moduleName::methodName():lineNumer message

instead of

//message

when calling

console.log("message")

Install

$ npm install ultimate-logger

Usage

var ultimateLogger = require('ultimate-logger');
ultimateLogger.enable();

Use cases

Formatting

Let's assume we've got a following module named "foo"....

module.exports = {
	bar: function(){
		return console.log("message");
	}
};

Setting up ultimate-logger for logging module and metod name:

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}}:{{methodName}}() ");
foo.bar();
//console printout is "foo:bar() message"

Setting up ultimate-logger for logging module and module's line number:

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}}::{{lineNumber}} ");
foo.bar();
//console printout is "foo::3 message"

Filtering

Let's assume we've got a following modules named "foo" and "bar"....

//foo
module.exports = {
  foo: function(){
		return console.log("message");
	}
	bar: function(){
		return console.log("message");
	}
};

//bar
module.exports = {
  foo: function(){
		return console.log("message");
	}
	bar: function(){
		return console.log("message");
	}
};

Setting up ultimate-logger for logging only from "foo" module

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}} ");
ultimateLogger.setFilter({
  moduleName: "foo"
});
foo.bar();
//console printout is "foo message"
bar.bar();
//there is no console printout here

Setting up ultimate-logger for logging only from "foo" method

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}} ");
ultimateLogger.setFilter({
  methodName: "foo"
});
foo.foo();
//console printout is "foo message"
bar.foo();
//console printout is "bar message"
bar.bar();
//there is no console printout here

Filter parameters can be combined. Array type is supported. Lets set up logging only from "foo" module methods "foo" and "bar"

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}} ");
ultimateLogger.setFilter({
  moduleName: "foo"
  methodName: ["foo", "bar"]
});
foo.foo();
//console printout is "foo message"
foo.bar();
//console printout is "foo message"

Ultimate-logger supports simple negative filtering. This is how to set it up to log all messages except from "foo" module

var foo = require("foo")
ultimateLogger.setFormat("{{moduleName}} ");
ultimateLogger.setFilter({
  moduleName: "!foo"
});
foo.foo();
//console printout is "foo message"
bar.foo();
//console printout is "bar message"
