Error in Browser
Error: Failed to lookup view index in views directory d:\Users\Admin\Documents\...\project\views
Question
I would like to structure my app by placing the view files in app/views/*.jade, but I cannot get it working so far, using app.set('views', ...) should work but it doesn't
console.log(viewPath) shows d:\Users\Admin\Documents\...\project\app\views
I also tried e.g. app.set('views', 'xxx') but the error still get stucked on the same path, it seems like app.set() has never been called, what's wrong here ?, please guide.
Thanks
Edit
It doesn't matter what I set using app.set('views', 'xxx') the error will always be Error: Failed to lookup view index in views directory d:\Users\Admin\Documents\...\project\views (always keep saying the same path)
I'm so sorry about router.get('/', ...), My actually project's files are different, so I was making mistake here

Answer 1

Try using
app.set('views', path.join(__dirname, 'views'));
Your app.js is in your app folder so I think
var viewPath = path.join(__dirname, 'app/views');
app.set('views', viewPath);
will look into app/app/views/ instead of app/views/ because of __dirname
__dirname is the directory in which the currently executing script resides.

I know it's too late, but might help someone who has the same problem. If you placed the rendering code in a separate file, then you need to use express.Router instead of app.get. For example,
const express = require('express');
const router = express.Router();
router.get('/', (req, res) => {
res.render('index', {title: 'Hey', message: 'Hello there!'});
});
module.exports = router;
Then in your app.js,
const router = require('./app/routes/routerName');
app.use('/', router);

Answer 3

I actually have separated files in my project, so I have app.get('/', ...) in the separated route file, then require it to use with app.use()
I really have no ideas but after moving only the app.get('/', ...) to the app.js, the problem has been solved
Thanks everyone

Answer 4

As mentioned by Roxinagi, you should be using app.get().
Everything else seems fine
app.get('/', function(req, res) {
res.render('index', { title: 'Home Page' } );
});

Answer 5

const path = require('path')
app.set('views', path.join(__dirname, 'app/views/'))
app.set('view engine','jade');
