Node.js · Full Stack Web Development

Explanation

Node.js runs JavaScript on the server so you can build APIs, scripts, and backend services with one language.

Code example

javascript

import { createServer } from "node:http";

const server = createServer((_req, res) => {
  res.writeHead(200, { "Content-Type": "application/json" });
  res.end(JSON.stringify({ ok: true, message: "Hello from Node" }));
});

server.listen(3000, () => {
  console.log("Server on http://localhost:3000");
});
