node.js know the file of where the require happened

I have 2 files

// file1.js
//some js code that will do what I ask in the question
module.exports = myFunc

//file2.js
require('./file1')

Is it possible, in any kind of way, for file1.js to know who required it? so when file2 requires file1, file1 will know that it was file2?

You noted that you wanted to use file1s functionality to create a file that is the same name as the callers. You could do this by utilising the __filename variable within a module.

Rather than try and access the caller, just pass this variable when using file1. For example:

require('./file1')(__filename)

Where file1 has something like:

module.exports = filename => {
    // create file here
}

While this should solve your problem, it seems like a strange requirement, and there is likely a better way to achieve what you are really after.
