I'm stuck :(

Question

I am trying to get a name from the user, output "Welcome, name!" to the screen and then reload the page and still have the same welcome message with the same name on, just like what Andrew wants.

I am able to get the name, save it in a cookie and output the message. But when I reload the page the message disappears and it asks the user for a name again.

I have put a comment beside the line that is giving me an error. It is saying that "username" is undefined. Andrew put the exact same line of code. Can anyone figure out what's wrong with my code?

My express file:

const express = require("express");
const bodyParser = require("body-parser");
const cookieParser = require("cookie-parser");
const app = express();

app.use(bodyParser.urlencoded({extended: false})); //middleware that makes working with form data easier
app.use(cookieParser()); 

app.set('view engine' , 'pug');

app.get('/' , (req, res) => {
    res.render("main", {question: "Who is Omar Ibn el Khattab?" , hint: "He is a muslim"});
});

app.get('/hello' , (req, res) => {
    res.render("hello" , {name: req.cookie.username}); //This is the line that is giving an error
});

app.post('/hello' , (req, res) => {
    res.cookie("username", req.body.username);
    res.render("hello" , {name: req.body.username});
});



app.listen(process.env.PORT , () => {
    console.log("app is running on port " + process.env.PORT);
});

Spencer Ailts on Jul 13 Hello Rashid,

It looks to me that you're missing an 's' in the line that is giving you an error.

try this

res.render("hello" , {name: req.cookies.username});
