Solving the CommonJS (Common JavaScript) and ECMAScript Modules (ESM) Problem

The following is a solution graciously provided by a Chilkat user trying to convert a node16 application using Common JS (require) to node20 using ESM (import).

CommonJS (Common JavaScript) and ECMAScript Modules (ESM) are two different module systems used in JavaScript environments. CommonJS is the module system used in Node.js and is characterized by `require()` and `module.exports` syntax, while ECMAScript Modules are the standard module system introduced in ECMAScript 6 (ES6) and are characterized by `import` and `export` statements.

'use strict'
import fp from 'fastify-plugin';
import os from 'os'
const drive = process.env.drive;

// The following fixes common libs when you cant import
import { createRequire } from "module";
const require = createRequire(import.meta.url);
// End The following fixes common libs when you cant import

console.log(" chilkat================== ")
 if (os.platform() == 'win32') {
  if (os.arch() == 'ia32') {
    var chilkat = require('@chilkat/ck-node20-win-ia32');
  } else {
    var chilkat = require('@chilkat/ck-node20-win64');
  }
}
