caller

caller

Figure out your caller (thanks to @substack).

Initialization Time Caller

// foo.js

var bar = require('bar');

// bar.js

var caller = require('caller');
console.log(caller()); // `/path/to/foo.js`

Runtime Caller

// foo.js

var bar = require('bar');
bar.doWork();

// bar.js

var caller = require('caller');

exports.doWork = function () {
    console.log(caller());  // `/path/to/foo.js`
};

Depth

Caller also accepts a depth argument for tracing back further (defaults to 1).

// foo.js

var bar = require('bar');
bar.doWork();

// bar.js

var baz = require('baz');

exports.doWork = function () {
    baz.doWork();
};

// baz.js

var caller = require('caller');

exports.doWork = function () {
    console.log(caller(2));  // `/path/to/foo.js`
};

callsite

The 'callsite' package provides a way to get detailed information about the call stack, including file paths, line numbers, and function names. It offers more detailed stack trace information compared to 'caller', which focuses on the immediate caller.

stack-trace

The 'stack-trace' package allows you to capture and manipulate stack traces in Node.js. It provides more comprehensive stack trace information and is useful for advanced debugging and error handling, whereas 'caller' is more lightweight and focused on identifying the immediate caller.
