Debug Utility Tool

This is a very easy to use tool that intends to help making logging and console.logging rich. This tool will allow you to have detailed message of what is going on with your project while debugging.

As developers we are constantly console.logging here and there to check what is returned, what is contained in a variable or to simply add tracks to know how the code is executing.

This tool allows you to set a message and everything else is done for you. The tool will give you the line and file the error happened at, who called, what method was used and if any data was returned and display it nicely.



Use the following command to install it:

npm install debug_utility_tool


You can simply require it to a variable and start using it.


Turn Debug Mode ON

This module blocks any console log among your code so to use this module you must first turn DEBUG mode ON:

Lets say you want to run server.js on debug mode

node server.js --debug true


node server.js -d true

Both ways you can set DEBUG on


The .debug funtion allows for 3 optional parameters and 1 required.

You must provide a message to it

util.debug('This message is required');

Specify a Message Type

util.debug('This message is required', 1);

You can pass it a 0, 1, or 2 and it cannot be a string;

  • 0 = Error;
  • 1 = Warn;
  • 2 = Info;

By default and message is set to be a Mesg defaultMsg

Pass some DATA

if you simply want to check what data is returned or being processed you can simply pass it as the 3 argument. This means that at this point you must specify a message type.

for example:

let n = 4;
function foo(number){
    util.debug('what is the number?', 2, number)
// --- outputs
/*- Debugging -----------------
    Time: 0:15 20
    Info: what is the number?
    Line: 7
    File: /Users/ecorreia/Sites/_tests/debugTool/node_modules/caller-id/lib/caller-id.js
    Func: getData | type: Object | method: getData
    Data: number 4

Callback function

util.debug('what is the number?', 2, number, function (err) {
    if(err == 0){
      // do something
      // do another

This callback function is used to see if the tool did its job or failed. You will double check if the tool threw an error and you didnt happen to catch it.
