Error: Failed to lookup view in Express

Note: my auto answer at end of the post

I'm trying to make a better experience of nodeJS and i don't really like to get all the script in one file.

so, following a post here i use this structure

./
config/
enviroment.js
routes.js
public/
css/
styles.css
images
views
index
index.jade
section
index.jade
layout.jade
app.js

My files are right now:

app.js

var express = require('express');
var app = module.exports = express.createServer();


require('./config/enviroment.js')(app, express);
require('./config/routes.js')(app);


app.listen(3000);

enviroment.js

module.exports = function(app, express) {
app.configure(function() {
app.use(express.logger());
app.use(express.static(__dirname + '/public'));
app.set('views', __dirname + '/views');
app.set('view engine', 'jade'); //extension of views


});


//development configuration
app.configure('development', function() {
app.use(express.errorHandler({
dumpExceptions: true,
showStack: true
}));
});


//production configuration
app.configure('production', function() {
app.use(express.errorHandler());
});


};

routes.js

module.exports = function(app) {


app.get(['/','/index', '/inicio'], function(req, res) {
res.render('index/index');
});


app.get('/test', function(req, res) {
//res.render('index/index');
});


};

layout.jade

!!! 5
html
head
link(rel='stylesheet', href='/css/style.css')
title Express + Jade
body
#main
h1 Content goes here
#container!= body

index/index.jade

h1 algoa

The error i get is:

Error: Failed to lookup view "index/index" at Function.render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\application.js:495:17) at render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\response.js:614:9) at ServerResponse.render (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\response.js:638:5) at c:\xampp\htdocs\nodejs\buses\config\routes.js:4:7 at callbacks (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:177:11) at param (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:151:11) at pass (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:158:5) at Router._dispatch (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:185:4) at Object.router [as handle] (c:\xampp\htdocs\nodejs\buses\node_modules\express\lib\router\index.js:45:10) at next (c:\xampp\htdocs\nodejs\buses\node_modules\express\node_modules\connect\lib\proto.js:191:15)

But i don't really know what is the problem...

I'm starting thinking is because the modules exports...

Answer: Far away the unique solution i found is to change the place i defined app.set('views') and views engine

I moved it to the app.js and now is working well.

var express = require('express');
var app = module.exports = express.createServer();




require('./config/enviroment.js')(app, express);


app.set('views', __dirname + '/views');
app.set('view engine', 'jade');


require('./config/routes.js')(app);


app.listen(3000);

I don't really understand the logic behind this but i gonna supose it have one.

npm install express@2.5.9 installs the previous version, if it helps.

I know in 3.x the view layout mechanic was removed, but this might not be your problem. Also replace express.createServer() with express()

Update:

It's your __dirname from environment.js
It should be:

app.use(express.static(__dirname + '../public'));

Adding to @mihai's answer:

If you are in Windows, then just concatenating __dirname' + '../public' will result in wrong directory name (For example: c:\dev\app\module../public).

Instead use path, which will work irrespective of the OS:

var path = require ('path');
app.use(express.static(path.join(__dirname + '../public')));

path.join will normalize the path separator character and will return correct path value.

I change the views folder name to views_render and also facing the same issue as above, so restart server.js and it works for me.

use this code to solve the issue 

app.get('/', function(req, res){
res.render("index");
});

Check if you have used a proper view engine. In my case I updated the npm and end up in changing the engine to 'hjs'(I was trying to uninstall jade to use pug). So changing it to jade from hjs in app.js file worked for me.

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

Just noticed that I had named my file ' index.html' instead for 'index.html' with a leading space. That was why it could not find it.

I had the same error at first and i was really annoyed. you just need to have ./ before the path to the template

res.render('./index/index');

Hope it works, worked for me.

This error really just has to do with the file Path,thats all you have to check,for me my parent folder was "Layouts" but my actual file was layout.html,my path had layouts on both,once i corrected that error was gone.

It is solved by adding the following code in app.js file

app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);


app.get('/', function(req, res){
res.render("index");
});

This problem is basically seen because of case sensitive file name. for example if you save file as index.jadge than its mane on route it should be "index" not "Index" in windows this is okay but in linux like server this will create issue.

1) if file name is index.jadge

app.get('/', function(req, res){
res.render("index");
});

2) if file name is Index.jadge

app.get('/', function(req, res){
res.render("Index");
});

I had the same issue and could fix it with the solution from dougwilson: from Apr 5, 2017, Github.

  1. I changed the filename from index.js to index.pug
  2. Then used in the '/' route: res.render('index.pug') - instead of res.render('index')
  3. Set environment variable: DEBUG=express:view Now it works like a charm.
小开

You could set the path to a constant like this and set it using express.

const viewsPath = path.join(__dirname, '../views')
app.set('view engine','hbs')


app.set('views', viewsPath)


app.get('/', function(req, res){


res.render("index");


});

This worked for me

I had this issue as well on Linux

I had the following


res.render('./views/index')


I changed it too
res.render('../views/index')

Everything is now working.

小开

In my case, I solved it with the following:

app.set('views', `${__dirname}/views`);
app.use(express.static(`${__dirname}/public`));

I needed to start node app.min.js from /dist folder.

My folder structure was:

Start app from /dist

小开

I had the same issue. Then just check the file directory in your explorer. Sometimes views folder isn't present.

In my case, I was deploying my web app on a Windows Server and I had a service set up to run a .bat file with only one line as content:

node D:\webapp\app.js

But this was not enough. I also had to change the directory before that, so I added the following line at the beginning of the .bat file:

cd D:\webapp

i had the same problem but, i change the name of the file from index.html to index.ejs and works!!!!

const express = require('express');
const router = express.Router();


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


router.get('/contact', (req, res) => {
res.render('contact', { title: 'Contact Page' });
});


module.exports = router;

and index.js

const express = require('express');
const morgan = require('morgan');
const path = require('path');
const app = express();






//settings
app.set('port', 4000);
app.set('views', path.join(__dirname,'views'));
app.set('view engine', 'ejs');


//middlewares


//routes
app.use(require('./routes'));


//static files


//listening
app.listen(app.get('port'), () => {
console.log('Server is running at http://localhost:'+app.get('port')+'/');
});

update: add this in index:

app.engine('html', require('ejs').renderFile);

小开 
app.get("/", (req, res) => {
res.render("home");
});


// the code below brought the error


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