Electron preload process

preload.js

// All of the Node.js APIs are available in the preload process.
// It has the same sandbox as a Chrome extension.

// The process.versions property returns an object listing the version
// strings of Node.js and its dependencies. process.versions.modules 
// indicates the current ABI version, which is increased whenever a 
// C++ API changes. Node.js will refuse to load modules that were compiled
// against a different module ABI version.

const { versions } = require('process')
window.addEventListener('DOMContentLoaded', () => {
    console.log(versions)
})
