Code: Here is the Code without EventEmitter and outsourcing modules. Everything in just one file.

const http = require('http'); const https = require('https');

const hostname = '127.0.0.1'; const port = 3000;

const server = http.createServer((req, res) => { res.statusCode = 200; res.setHeader('Content-Type', 'text/plain'); homeVerleitung(req, res); userVerleitung(req, res); });

server.listen(port, hostname, () => { console.log(Server running at http://${hostname}:${port}/); });

function homeVerleitung(request, response) { if (request.url === '/') { response.setHeader('Content-Type', 'text/plain'); response.write('Home Header\n'); response.write('Home Content \n'); response.end('Home Footer\n'); } }

function userVerleitung(request, response) { if (request.url !== '/') { response.setHeader('Content-Type', 'text/plain'); const usedUrl = request.url.replace('/', ''); const userData = getProfile(usedUrl); userData .then((d) => { response.write('User Header\n'); response.write(${d.name}\n); response.end('User Footer\n'); }) .catch((e) => { response.write('Error Header\n'); response.write(e + '\n'); response.end('Error Footer\n'); }); } }

function getProfile(url) { return new Promise((resolve, reject) => { https .get(https://teamtreehouse.com/${url}.json, (res) => { let body = ''; res.on('data', (d) => { body += d.toString(); }); res.on('end', (d) => { try { const jsonBody = JSON.parse(body); resolve(jsonBody); } catch (e) { const error = new Error(We have an Parsing-Error: ${e}); console.log(try..catch Error ${error}); reject(User ${url} is not available); } }); }) .on('error', (e) => { console.log(.on('error') Error ${e}); }); }); }
