const router = require('./router.js');
const http = require('http');

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

const server = http.createServer((req, res) => {
    router.home(req,res);
    router.user(req,res);
});

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

function home(req,res) {
    if (req.url === "/") {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'text/plain');
        res.write('Header\n');
        res.write('Search\n');
        res.end('Footer\n');
    }
}

function user(req,res) {
    const username = req.url.replace("/","");
    if (username.lenght > 0) {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'text/plain');
        res.write('Header\n');
        res.write(username + '\n');
        res.end('Footer\n');
    }
}

module.exports.home = home;
module.exports.user = user;

the first is in an example.js file and the second in the router.js fils

Hi Sandro, I had the same problem , it is because the documentation has slightly changed and the copy-paste-example from node.js.org uses the setHeader-method. You can set that method only once (with me this was a message in the console), and after I removed the res.setHeader from the user-function all works fine.
