Get the path to the file from which the module is called?

Let's say I have a node.js module

module.exports = function () {
  console.log(__filename);
}

      

        
        
        
      

    

And in the main file, I call it like

var x = require('path/to/module');
x();

      

        
        
        
      

    

This gives me the path to the module file. For example, if I saved the module in ~/project-root/lib/mod.js

and the file main.js

is in ~/project-root/main.js

, this setting gives me the output:

~/project-root/lib/mod.js

      

        
        
        
      

    

I want to use something instead __filename

in a module that gives me the location of the file it was called from. (for example, in this example, the output will be ~/project-root/main.js

).

The module can be located anywhere. Therefore, using path

just this example for configuration will fail in other scenarios (for example, if the module is stored in the ~/project-root/node_modules/

node.js modules or global directory.

I have a feeling this is pretty trivial and I am missing something. But I didn’t find a solution from anything that Google relented within an hour of searching. I may be using the wrong keywords!
