JavaScript Build a Simple Dynamic Site with Node.js Handling Routes in Node.js Populating User Information

Any username I type in after my localhost:(port) is not being displayed on the page

Hello I'm about 6 minutes into the video when we're testing if everything is working with a simple response where you type in localhost:(port)/chalkers to display the response.write(values.username + "has "+ values.badges + "badges\n");.

However nothing is being written to the page for me.

A few things before I post my code: I am running my own node.js environment on my local computer and not using the treehouse option and my port is: 1337. I'm pretty sure that something has been overlooked in my code because when I start the server without any searching of usernames it all shows up fine with Header, Search, Footer, but a /chalkers for example just gives me Header, Footer.


    var Profile = require("./profile.js")

    // Handle the HTTP route GET / and POST  / i.e. Home
    function home(request, response) {
        //if url = "/" && GET
            //url is a property of the incoming message
        if (request.url === "/") {
                //show search field
            response.writeHead(200, { 'Content-Type': 'text/plain' });

            //if url = "/" && POST
                //redirect to /:username

    // Handle the HTTP route GET / :username i.e. /mauricetafollacunningham
    function user(request, response) {
    //if url = "/....."
    var username = request.url.replace("/", "");

    if (username.length > 0) {
        response.writeHead(200, { 'Content-Type': 'text/plain' });
            //get json from Treehouse
            var studentProfile = new Profile(username);
                //on "end"
            studentProfile.on("end", function(profileJSON){
                //show profile

                //Store the values which we need
                var values = {
                    avatarUrl: profileJSON.gravatar_url,
                    username: profileJSON.profile_name,
                    badges: profileJSON.badges.length,
                    javascriptPoints: profileJSON.points.JavaScript
                //Simple Response
                response.write(values.username + "has "+ values.badges + "badges\n");
            //on "error"
            studentProfile.on("error", function(error){
            // show error



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


//Problem: We need a simple way to look at a user's badge count and JavaScript points from a web browser
//Solution: Use node.js to perform the profile lookups and serve our template via HTTP

var router = require("./router.js");

//Create a web server
const http = require('http');

const hostname = '';
const port = 1337;

http.createServer((request, response) => {
  router.home(request, response);
  router.user(request, response)
  //response.end('Hello World\n');
}).listen(port, hostname, () => {
  console.log("Server running at http://${hostname}:${port}/");

Okay so I figured out that I needed to require both http and https in profile.js and change the references on a few lines cool, but now after I enter in usernames my server eventually dies. I'm given Error: write after end in the console.

This one has me really stuck.

Are you getting any output at all? I am getting something similar.

I put a console.log in studentProfile.on("error", function(error){ // show error response.end("Footer\n") }); It looks like I am getting an error there [Error: There was an error getting the profile for favicon.ico. (Not Found)]

It looks like profile is not emitting the correct data.
