# [`oro:module`](/runtime/docs/javascript/module/)

[`oro:module`](/runtime/docs/javascript/module/) exposes module-loader helpers and builtin-module inspection.

## Examples

Inspect builtin modules and create a `require()` function when you need one:

```js
import Module, { builtinModules, isBuiltin, createRequire } from 'oro:module'

const require = createRequire(import.meta.url)

console.log(isBuiltin('oro:path'))
console.log(Object.keys(builtinModules).length)
console.log(typeof Module)
console.log(typeof require)
```
