## CommonJS Module Loading
|
|
|
|
`createRequire(...)` is provided to create a `require` function for loading CJS
|
|
modules. It also sets supported globals.
|
|
|
|
```ts
|
|
import { createRequire } from "https://deno.land/std@$STD_VERSION/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");
|
|
```
