Simple implementation of HTTP in Node

SimpleHTTPServer.js

const net = require('net');
const server = net.createServer(function (socket) {
    socket.on('data', function (data) {
        const header = data.toString();
        console.log("--------start request--------");
        console.log(header);
        console.log("--------end request--------");

        let response = "HTTP/1.1 200 OK\r\n";
        body = "<h1> HELLO WORLD &#128521; </h1>";
        response += 'Content-Length: ' + body.length + '\r\n';
        response += 'Content-Type: text/html; charset=utf-8\r\n';
        response += '\r\n';
        response += body;
        socket.write(response);
        socket.pipe(socket);
    })

server.listen(8080, 'localhost');
