Первая программа на Node.js — Шаг 6 — HTTP-сервер на встроенном `http`

import http from 'node:http';

const PORT = process.env.PORT || 3000;

const server = http.createServer((req, res) => {
  if (req.method === 'GET' && req.url === '/health') {
    res.writeHead(200, { 'Content-Type': 'application/json; charset=utf-8' });
    res.end(JSON.stringify({ status: 'ok' }));
    return;
  }
  res.writeHead(404, { 'Content-Type': 'text/plain; charset=utf-8' });
  res.end('Not found\n');
});

server.listen(PORT, () => {
  console.log(`Raw API: http://127.0.0.1:${PORT}`);
});
