[Q] How to extract my module

[silverqx]

I'm doing custom bootstrap-sass js build, I have created this module:
resources/assets/js/external/bootstrap.js

import 'bootstrap-sass/assets/javascripts/bootstrap/transition';
// import 'bootstrap-sass/assets/javascripts/bootstrap/alert';
import 'bootstrap-sass/assets/javascripts/bootstrap/button';
// import 'bootstrap-sass/assets/javascripts/bootstrap/carousel';
import 'bootstrap-sass/assets/javascripts/bootstrap/collapse';
import 'bootstrap-sass/assets/javascripts/bootstrap/dropdown';
import 'bootstrap-sass/assets/javascripts/bootstrap/modal';
// import 'bootstrap-sass/assets/javascripts/bootstrap/tab';
// import 'bootstrap-sass/assets/javascripts/bootstrap/affix';
// import 'bootstrap-sass/assets/javascripts/bootstrap/scrollspy';
// import 'bootstrap-sass/assets/javascripts/bootstrap/tooltip';
// import 'bootstrap-sass/assets/javascripts/bootstrap/popover';

And importing it in resources/assets/js/app.js like this:

import 'jquery';
import './external/bootstrap';

// Namespaces
window.crystal = {};
window.crystal.configPhp = {};

window.axios = require('axios');

window.axios.defaults.headers.common['X-CSRF-TOKEN'] = window.Laravel.csrfToken;
window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

How can I extract this ./external/bootstrap module, I have tried many combinations, but only one which works, is to reference every file like this:

mix.extract([
    'bootstrap-sass/assets/javascripts/bootstrap/transition',
    'bootstrap-sass/assets/javascripts/bootstrap/button',
    'bootstrap-sass/assets/javascripts/bootstrap/collapse',
    'bootstrap-sass/assets/javascripts/bootstrap/dropdown',
    'bootstrap-sass/assets/javascripts/bootstrap/modal',
    'axios',
]);

I want to something like this:

mix.extract([
    './external/bootstrap',
// 'resources/assets/js/external/boostrap', // or this
    'axios',
]);

Can be that done by laravel mix? Or this is not supported now?

Thank you for any suggestions.

Dont know if we can extract the module that was not installed through npm, if webpack can do this then mix can also do this.

Thank you for reply, of course that webpack can do this, it can do it by CommonsChunkPlugin, but important info is, that it's not possible with mix.extract() now ( it's of course all right ), I think this issue can be closed.
