Nodejs: How to locate source file of process.binding()?

Question

I am trying to find the location of the source file for an internal module called by process.binding('base_filter') in "base-filter.js". It's a react/electron app using electron-prebuilt.

This script is located in:

    +-- electron-prebuilt
    |   +-- dist
    |       +-- resources
    |           +-- electron.asar
    |               +-- filtering
    |                   +-- api
    |                       +-- exports
    |                           +-- base-filter.js

I've searched exhaustively for solutions, I've tried:

    var natives = process.binding('natives');
    for (var key in natives) {
        console.log(key);
    }

From How to obtain a list of all available Node.js modules?

Which didn't show the module.

I've tried:

node.js Internals: How can I find out where `process.binding('eval')` gets defined?

What is `process.binding('fs')` in `fs.js`?

I've tried batch searching every single file in the code-base for mention of "base_filter" with no success, i also tried searching my PCs appdata and user files thinking it might be caching somewhere, no success.

I'm wringing my hair out over this, I just need to be able to trace where it's being loaded from so i can edit it/ fix any problems.

I would appreciate any help, thank you.
