caller-path

What is caller-path?

The caller-path npm package is designed to help developers retrieve the path of the file that calls a function. This can be particularly useful for debugging, logging, and tracking the flow of a program, especially in complex applications where functions are called from multiple places.

What are caller-path's main functionalities?

Get caller file path

This feature allows developers to log or retrieve the path of the file that called a function. In the provided code, the function `whoCalled` uses `callerPath()` to print the path of the caller file.

const callerPath = require('caller-path');

function whoCalled() {
  console.log(callerPath());
}

module.exports = whoCalled;

Other packages similar to caller-path

callsites

The 'callsites' package provides functionality to get the call sites (stack frames) of the V8 stack trace API, which can be used to find the path of the caller. It offers more detailed control over the stack trace compared to caller-path, allowing developers to access deeper insights into the call stack.

stack-trace

This package is used to extract a stack trace from within a running node.js application, similar to caller-path. It differs in that it provides a more comprehensive set of features for manipulating and analyzing the stack trace beyond just retrieving the caller's path.

Get the path of the caller module

You can't use module.parent as modules are cached and it will return the first caller module, not necessarily the current one.

Install

$ npm install --save caller-path

Usage

// foo.js
var callerPath = require('caller-path');

module.exports = function () {
	console.log(callerPath());
