if(request.url === "/"): Cannot read 'url' property of undefined

I checked and double checked and my code looks ok but I'm still getting this error: 

/home/treehouse/workspace/router.js:2                                                             
  if(request.url === "/"){                                                                        
            ^

My router.js file is:

function home(request, response){
  if(request.url === "/"){
    response.write("Header \n");
    response.write("Search \n");
    response.write("footer \n");
  }
 }

function user(request, response){
 var username = request.url.replace("/", "");
  if(username.length > 0)
  {
    response.write("Header \n");
    response.write(username + "\n");
    response.write("Foother");
  }

}

app.js:

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

var http = require('http');
http.createServer(function (request, response) {
  response.writeHead(200, {'Content-Type' : 'text/plain'});
  router.home(request, response);
  router.user(request, response);
}).listen(3000);
console.log('Server running at http://<workspace-url>/');

Any ideas?

Perhaps you are missing 'http' module requirement:

var http = require('http');

I have that in the 3rd line of the app.js

"module.exports" are missing. I modified your "router.js" as below and it's working fine:

[router.js]

function home(request, response){
    if(request.url === "/"){
        response.write("Header \n");
        response.write("Search \n");
        response.write("footer \n");
        response.end(0);
    }
}

function user(request, response) {
    var username = request.url.replace("/", "");
    if (username.length > 0) {
        response.write("Header \n");
        response.write(username + "\n");
        response.write("Foother");
        response.end(0);
    }

}

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