.babelrc

{
  "presets": [
    "electron"
  ]
}

_run.cmd

#!/env/bash

echo same for OSX / WIN !

echo install basics
npm i electron babel-core babel-preset-electron 

echo should fix native modules -- https://github.com/royaltm/node-murmurhash-native/issues/13#issuecomment-412664883
echo but only for current OS - does not work with electrons cross building
npm i electron-rebuild
node_modules/.bin/electron-rebuild

echo run
node_modules/electron/dist/electron index.js

app.mjs

// some exerpt from a current project

import fs from 'fs';
import path from 'path';
import murmur from 'murmurhash-native/stream';


console.log('app should have started...');

let hasher = murmur.createHash('murmurhash32', {seed: 478932, encoding: 'hex', endianness: 'platform'});

let filepath = path.resolve('./', 'app.mjs');

        fs.createReadStream(filepath)
        .pipe(hasher)                            // create hash string
        .on('data',   d => data += d.toString()) // collect stream text from pipe->hash
        .on('error', () => resolve(null))        // do not throw an error on error (so no reject)
