How to create multiple entry points and use CommonsChunkPlugin in Ellixir webpack?

I created a simple webpack.config.js

    var path = require("path");
    var CommonsChunkPlugin = require("webpack/lib/optimize/CommonsChunkPlugin");
    
    module.exports = {
        context: path.join(__dirname, "resources/assets"),
    
        entry: {
            login: "./js/login.js",
            post: "./js/post.js",
            common: "./js/common.js"
        },
        output: {
            path: path.join(__dirname, "public/js"),
            filename: "[name].js"
        },
        plugins: [
            new CommonsChunkPlugin({
                filename: "common.js",
                name: "common"
            })
        ]
    };

but what is the correct way to make Elixir use it?

Looks like it still needs a file path, that is mix.webpack() throws error.

mix.webpack('') seems to work but looks weird, not sure if it is the correct way.

UPD: also it fails during production build

Starting 'webpack'...

Hmm, not sure how to compress this type of file. Stick with CSS or JavaScript files!

mix.webpack(['post.js', 'login.js', 'common.js']) and mix.webpack('*.js') seem to work but looks like it was not intended to be used like this because destination output looks weird: public\js\all.js (though all.js is not created)
