const getCallerFile = require('get-caller-file');

const numArray = [1,2,3,4,5];
if (numArray.some(num => {
    const file = getCallerFile();
    console.log(`we are in ${file}`);
    return true;
})) {
  console.log("see above ^^ shouldn't be null");
}

output:

we are in null
see above ^^ shouldn't be null

What has changed between 1.0 and 2.0?

Seeing this error when I try to build an application with webpack that has get-caller-file as an npm dependency:

Module Warning (from ../../node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from '/home/me/app/node_modules/get-caller-file/index.ts' file: 
Error: ENOENT: no such file or directory, open '/home/me/app/node_modules/get-caller-file/index.ts'

Your sourcemap file is referencing index.ts as a source, but that file isn't present in the downloaded package.

• fixtures (3)
• tests.js

Please add a license file as the ISC license requires it to be with the code.

`// root/index.js
module.exports = function() { return getCallerFile(); }

// root/dir/app.js
const func = require('../index.js');
func(); // returns root/index.js`

Firstly encourntered this when using TS-NODE. It occurs in node too. Caller file is app.js yet definition file index.js is returned.

What does this project do?

Why reason get-caller-file only allow 6.x, 8.x, or above 10.x node.js version?
