// webpack.config.js
module: {
    rules: [
        {
            test: /run\d\.js$/, 
            exclude: /(node_modules|bower_components)/,
            use: [
                {
                    loader: path.resolve(__dirname, '../index.js'),
                    options: {
                        babel: `require('babel-register')({
                            presets: ['babel-preset-env']
                        });` 
                        // can use custom babel config or default config.
                        // default config:
                        // require('@babel/register')({
                        //     presets: ['@babel/preset-env']
                        // });
                    },  
                   
                },
                {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-env']
                    }
                }
            ]
        }
    ]
}

// run2.js
import a from './run/module';
var xx = {
    a: {
        x: 1,
        y: 2,
        z: 3,
        0: 4,
    },
};
for (let x of [1, 2, 3]) {
    xx['a' + x] = Object.assign({}, xx.a);
    delete xx['a' + x][0];
}
const test = require('./run/cjs');

export const run2 = Object.assign({
    xx,
    a,
    d() {
        return 5;
    },
}, test);

note

1. this loader serialized data by JSON.stringify.
2. this loader will not watch run script file dependent files, so need to manual trigger run script file file change if dependent files changed.
