Create a require function that can be used to import CJS modules. Follows CommonJS resolution similar to that of Node.js, with node_modules lookup and index.js lookup support. Also injects available Node.js builtin module polyfills.

const require_ = createRequire(import.meta.url);
const fs = require_("fs");
const leftPad = require_("left-pad");
const cjsModule = require_("./cjs_mod");
