# get-caller-file [](https://travis-ci.org/stefanpenner/get-caller-file) [](https://ci.appveyor.com/project/embercli/get-caller-file/branch/master) 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. Inspired by http://stackoverflow.com/questions/13227489 *note: this relies on Node/V8 specific APIs, as such other runtimes may not work* ## Installation ```bash yarn add get-caller-file ``` ## Usage Given: ```js // ./foo.js const getCallerFile = require('get-caller-file'); module.exports = function() { return getCallerFile(); // figures out who called it }; ``` ```js // index.js const foo = require('./foo'); foo() // => /full/path/to/this/file/index.js ``` ## Options: * `getCallerFile(position = 2)`: where position is stack frame whos fileName we want.
