I have run into two problems. One is that res.redirect won't work, after submitting the form, the page stays at "/hello". And also my main page will not display the typed username, instead displaying absolutely nothing where the variable "name" is. Here is my code. Thanks ahead for any help you guys can give.
Here is the app.js file.
const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const app = express();
app.use(bodyParser.urlencoded({extended: false }));
app.use(cookieParser());
app.set('view engine', 'pug')
app.get('/', (req, res) =>{
const name = req.cookies.username;
res.render("index" , { name});
});
app.get('/cards', (req, res) =>{
res.render('card', { prompt: "Who is buried under Grant's Tomb"});
});
app.get('/hello', (req, res) =>{
res.render('hello');
});
app.post('/hello', (req, res) =>{
res.cookie('username', req.body.username);
res.redirect('/');
});
app.listen(3001, ()=> {
console.log('The application is running on port 3000')
});
And here is the index.pug file
extends layout.pug
block content
section#content
h2 Welcome,#{name}!

app.post('/hello', (req, res) => {
res.cookie('username', req.body.username);
res.redirect( '/', 302, {name: req.cookies.username});
});
The whole answer is: app.js
const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const app = express();
app.use(bodyParser.urlencoded({extended: false}));
app.use(cookieParser());
app.set('view engine', 'pug');
app.get('/', (req, res) => {
const name = req.cookies.username;
res.render('index', {name});
});
app.get('/hello', (req, res) => {
res.render('hello');
});
app.post('/hello', (req, res) => {
res.cookie('username', req.body.username);
res.redirect( '/', 302, {name: req.cookies.username});
});
app.get('/cards', (req, res) => {
res.locals.prompt = "Who is buried in Grant's tomb?";
res.render('card', {});
});
app.listen(3000, ()=> {
console.log('The application is running on localhost:3000!');
});
Which it does work for me now.
Presuming you updated index.pug to
extends layout.pug
block content
section#content
h2 Welcome, #{name}!
