Node.js vs Deno Vergleich

// Node.js - HTTP-Server und Dateizugriff
const http = require('http');
const fs = require('fs').promises;

const server = http.createServer(async (req, res) => {
  if (req.url === '/data') {
    try {
      const data = await fs.readFile('./data.json', 'utf-8');
      res.writeHead(200, { 'Content-Type': 'application/json' });
      res.end(data);
    } catch (err) {
      res.writeHead(500);
      res.end('Serverfehler');
    }
  }
});

server.listen(3000, () => console.log('Port 3000 aktiv'));

// Deno - HTTP-Server und Dateizugriff (natives TypeScript)
import { serve } from "https://deno.land/[email protected]/http/server.ts";

async function handler(req: Request): Promise<Response> {
  const url = new URL(req.url);
  if (url.pathname === "/data") {
    try {
      const data = await Deno.readTextFile("./data.json");
      return new Response(data, {
        headers: { "Content-Type": "application/json" }
      });
    } catch {
      return new Response("Serverfehler", { status: 500 });
    }
  }
  return new Response("Nicht gefunden", { status: 404 });
}

serve(handler, { port: 3000 });
