6 This is a utility, which allows a function to figure out from which file it was invoked. It does so by inspecting v8's stack trace at the time it is invoked.
8 Inspired by http://stackoverflow.com/questions/13227489
10 *note: this relies on Node/V8 specific APIs, as such other runtimes may not work*
15 yarn add get-caller-file
24 const getCallerFile = require('get-caller-file');
26 module.exports = function() {
27 return getCallerFile(); // figures out who called it
33 const foo = require('./foo');
35 foo() // => /full/path/to/this/file/index.js
41 * `getCallerFile(position = 2)`: where position is stack frame whos fileName we want.
