CommonJS Module Loading

createRequire(...) is provided to create a require function for loading CJS modules. It also sets supported globals.

import { createRequire } from "https://deno.land/std/node/module.ts";

const require = createRequire(import.meta.url);
// Loads native module polyfill.
const path = require("path");
// Loads extensionless module.
const cjsModule = require("./my_mod");
// Visits node_modules.
const leftPad = require("left-pad");
