Minimalistisches Routen-Dispatching mit dem Node.js HTTP-Modul

import http from 'node:http';
 
const routes = new Map([
  ['GET /api/status', (req, res) => res.end(JSON.stringify({ status: 'ok' }))],
  ['POST /api/echo', (req, res) => res.end('Echo response')]
]);
 
const server = http.createServer((req, res) => {
  const routeKey = `${req.method} ${req.url}`;
  const handler = routes.get(routeKey);
 
  if (!handler) {
    res.statusCode = 404;
    return res.end(JSON.stringify({ error: 'Route not found' }));
  }
 
  res.setHeader('Content-Type', 'application/json');
  handler(req, res);
});
 
server.listen(3000);
