Use Node.js built-in modules

Deno supports most built-in Node.js modules natively - you can include them in your code using "node:" specifiers in your imports.

Import the os module from core Node to get operating system info

import os from "node:os";

Use the module as you would in Node.js

console.log("Current architecture is:", os.arch());
console.log("Home directory is:", os.homedir());

Run this example locally using the Deno CLI:

deno run --allow-env https://raw.githubusercontent.com/denoland/deno-docs/main/by-example/node.ts
