27,371 PointsWhy am I seeing two occurrences of middleware `one`, `one and a half`, and `two` for any view?
With the loading of any page, I see the numbers twice locally in my terminal - but, not in the video.
So, instead of...
1
1.5
2
...I'm seeing:
1
1.5
2
1
1.5
2
Has anyone else experienced this?

27,371 PointsI'm noticing that it's not doing it in Chrome (which explains why it isn't the result being seen in the video), but I use Firefox as my primary browser since it's my "neutral zone" between Chrome and IE/Edge in terms of cross-compatibility. I checked in Firefox Developer Edition and Firefox - same issue. In Chrome, it only does it once, and I'd like to know why - even if it's a setting I should be aware of in Firefox.

27,371 PointsI found my own answer...
Upon looking at the console
> requests
log, favicon
was giving me a 404 error. By installing npm i serve-favicon --save
and adding const favicon = require('serve-favicon');
as well as app.use(favicon(__dirname + '/favicon.ico'));
to app.js
- I no longer get a 404 that seemed to have given Firefox a case of the hiccups.
The current code is now:
'use strict';
const express = require('express');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const favicon = require('serve-favicon');
const app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
// Template Engine
app.set('view engine', 'pug');
// Favicon
app.use(favicon(__dirname + '/favicon.ico'));
// Middleware
app.use((req, res, next) => {
console.log('1');
next();
},
(req, res, next) => {
console.log('1.5');
next();
});
app.use((req, res, next) => {
console.log('2');
next();
});
// Index
app.get('/', (req, res) => {
// Get 'username' cookie
const name = req.cookies.username;
if (name) {
res.render('index', {name});
} else {
res.redirect('/login')
}
});
// Login
app.get('/login', (req, res) => {
// Get 'username' cookie
const name = req.cookies.username;
if (name) {
res.redirect('/')
} else {
res.render('login');
}
});
app.post('/login', (req, res) => {
res.cookie('username', req.body.username);
res.redirect('/');
});
// Logout
app.post('/logout', (req, res) => {
res.clearCookie('username');
res.redirect('/login');
});
// Flashcards
const cardColors = [
'red',
'white',
'blue'
];
app.get('/cards', (req, res) => {
res.locals.title = "Flash Cards";
res.render('cards', {
hint: "This is a hint, shhhhhh!",
colors: cardColors
});
});
// Server
app.listen(3000, () => {
console.log("Running on http:localhost:3000");
});
I then added a transparent favicon.ico
generated online, to the path defined in app.js
(which would normally be in a folder of public assets, like /public/images/favicon.ico
.)
