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");
