who-logs-to-console

You have some components writing very verbose logs and you don't know which? Inspired by the well known why-is-node-running package, who-logs-to-console is here to help you.

Installation

Any node version:

npm i who-logs-to-console -g

Usage

require('who-logs-to-console') // should be your first require

// catches console outputs
console.log("Hello World!");
console.error("Failed Hello World?!");

// also catches more low-level stuff
process.stdout.write("Who does that?\n");
process.stderr.write("Seriously!?\n");

Save the file as example.js, then execute:

node ./example.js

Here's the output:

Hello World!
