JavaScript Build a Simple Dynamic Site with Node.js Handling Routes in Node.js Handling Routes Review

challenge task 1 of 2. Node.js,

We've been tasked to continue with this prototype site. Have a look in the index.js and routes.js file and familiarize yourself. In the routes.js, just like the other two functions create an about function for a /about route. Have it print out "About\n" to the response. Remember to make this accessible by other files.

What have I missed?????

here is my code

function root(request, response) {
    if(request.url == "/") {
        response.writeHead(200, {'Content-type': "text/plain"});
        response.end("Home\n");
    }
}

function contact(request, response) {
    if(request.url == "/contact") {
        response.writeHead(200, {'Content-type': "text/plain"});
        response.end("Contact\n");
    }
}
function about(request, response) {
  if(request.url == "/about")  {
    response.writeHead(200, {"Content-type" : "text/plain"});
    response.end("About\n");
  }
}

module.exports.root = root;
module.exports.contact = contact;
var http = require("http");
var routes = require("./routes.js");

http.createServer(function(request, response){
    routes.root(request, response);
    routes.contact(request, response);
}).listen(3000);

Hi cathy mitchell,

You're almost there; you simply need to export your about function in routes.js and call it from within the createServer callback function.

routes.js
function root(request, response) {
    if(request.url == "/") {
        response.writeHead(200, {'Content-type': "text/plain"});
        response.end("Home\n");
    }
}

function contact(request, response) {
    if(request.url == "/contact") {
        response.writeHead(200, {'Content-type': "text/plain"});
        response.end("Contact\n");
    }
}

function about(request, response) {
  if(request.url == "/about")  {
    response.writeHead(200, {"Content-type" : "text/plain"});
    response.end("About\n");
  }
}

module.exports.root = root;
module.exports.contact = contact;
module.exports.about = about;
index.js
var http = require("http");
var routes = require("./routes.js");

http.createServer(function(request, response){
    routes.root(request, response);
    routes.contact(request, response);
    routes.about(request, response);
}).listen(3000);

Happy coding!

here is the error message I am getting :

Bummer! Routes is not defined.

I copied what you had there and it didn't work as you can see..

I just tried the same code above again and it works without any issues, are you sure you have all three functions defined and exported? Could you take a screenshot of what you have currently?

Chris,

Thank you for all your help. It finally went through. I had to log out and go back and reinsert it for the 4th time.

Hey Cathy,

You may kick yourself when I tell you... You code is all correct. You just forgot to export the module. At the bottom of the other two, you missed adding the "about" export. :)

routes.js
module.exports.root = root;
module.exports.contact = contact;
module.exports.about = about;

Keep Coding! :) :dizzy:

Jason,

Here is the code I get when I put the above in

Bummer! Routes is not defined

/HERE YOU/WE GO/ function root(request, response) { if(request.url == "/") { response.writeHead(200, {'Content-type': "text/plain"}); response.end("Home\n"); } }

function contact(request, response) { if(request.url == "/contact") { response.writeHead(200, {'Content-type': "text/plain"}); response.end("Contact\n"); } }

function about(request, response) { if(request.url == "/about") { response.writeHead(200, {"Content-type" : "text/plain"}); response.end("About\n"); } } var http = require("http"); var routes = require("./routes.js");

http.createServer(function(request, response){ routes.root(request, response); routes.contact(request, response); routes.about(request, response); }).listen(3000);

module.exports.root = root; module.exports.contact = contact; module.exports.about = about;
