Express + pug – JavaScript, AJAX, jQuery – Fórum – Programujte.com

Dobrý den jsem v expressu a node.js nováček a zamrzl jsem hned u prvního problému. Mám kód:

// JavaScript source code
const express = require('express');
const pug = require('pug');
const app = express();
app.set('view engine', 'pug');
app.set('views', 'views');
app.get('/', (req, res) => {
    res.render(index.pug);
});
app.listen(3000, () => console.log('Listening on port 3000'));

hází to chybu:

ReferenceError: index is not defined

    at Layer.handle [as handle_request] (C:\Users\User\node.js\node_modules\express\lib\router\layer.js:95:5)

index.pug je v adrasáři view a stejně to nefunguje . Díky za nakopnutí.

#1 vagus
no tvrdi ti to, ze promenna index nema zadny atribut pug (asi proto, ze neexistuje)... A pokud tvrdis, ze je to soubor, tak bych cekal spise neco jako 'index.pug'

#2 KIIV
to tam je - index.pug

#3 vagus
myslim doslova v uvozovkach, ne bez nich

res.render(index.pug); // urcite to ma byt takto?, jak naznacuje kiiv, v js se pouzivaji uvozovky,
//pokud predavas funkci text, jako treba nazev souboru
res.render('index.pug');

...asi ve 2/3 te stranky...

mkdir views
touch views/index.pug


--- index.pug ---

doctype html
html(lang='en')
 head
   title Hello, World!
 body
   h1 Hello, World!


--- app.js ---

const express = require('express');
const app = express();
app.set('view engine', 'pug');

app.get('/', (req, res) => {
  res.render('index');
});

app.listen(3000, () => {
  console.log('Listening on port 3000...');
});
