Express JS not rendering jade template - node.js

I'm going to keep this short, I'm just trying to render a jade template using express js.
I'm using express 3.0.0rc5 and jade 0.27.6.
Here's my jade templates, the layout:
// test-layout.jade
doctype 5
html
head
title My title
block head
body
#content
block content
And the index:
// test-index.jade
extends test-layout
block head
script(src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js")
block content
h1 My page
Here's some excerpts from app.js:
var app = express();
// Configuration
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
app.get('/test-jade', function(req, res) {
res.render('test-index', {}, function(err, html) {
});
});
app.get('/test', function(req, res) {
res.send('this works');
});
Now whenever I try to go to http://myurl.com/test-jade the browser just hangs and timesout without showing any output in the console (even though I'm in dev mode).
However when I go to http://myurl.com/test I see 'this works'.
I feel like I'm missing something really simple here, I'm currently upgrading from 2.5 to 3.0.
Thanks in advance if anyone has advice.

Is it the blank call back?
res.render('test-index', {}, function(err, html) {
});
In my app I'm using
res.render('test-index', {});

res.render showing html code than rendering the page

I am new to ejs and I am trying to render a page using it. Here is the code
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.get ("/user",(req,res) =>{
res.header("Content-Type",'application/json');
var id_token_decode=jwt_decoder(req.session.tokenSet.id_token);
var decoded = jwt_decoder(req.session.tokenSet.access_token);
console.log(id_token_decode)
console.log(decoded);
console.log(path.join(__dirname + '/views/citizenHome.html'))
res.render('citizenHome.ejs')
})
It is showing the html code rather than actually rendering the page. Can anyone help me?
Remove res.header("Content-Type",'application/json'); this line from the route
app.get ("/user",(req,res) =>{
// res.header("Content-Type",'application/json'); <-- remove this line
var id_token_decode=jwt_decoder(req.session.tokenSet.id_token);
var decoded = jwt_decoder(req.session.tokenSet.access_token);
console.log(id_token_decode)
console.log(decoded);
console.log(path.join(__dirname + '/views/citizenHome.html'))
res.render('citizenHome.ejs')
})
And also, what does /views/citizenHome.html this file do?

Send a parameter along with sendfile

I am using nodejs
i have this code
var someparameter ="teststst";
var fileLocation = path.resolve(__dirname + '/../public/resetpassword.html');
console.log(fileLocation);
res.sendfile(fileLocation);
I want to send someparameter in resetpassword.html
Can anybody tell me how to do this ?
Thanks
You can't. (not without an engine)
Passing parameters to the html won't have any effect (and isnt possible)
You can use a template engine such as jade (or EJS if you want to stay with HTML)
Defined as:
app.engine('.html', require('ejs').__express);
app.set('views', __dirname + '/views');
app.set('view engine', 'html');
And than you can 'render' view with parameters:
app.get('/', function(req, res){
res.render('index', {
users: users,
title: "EJS example",
header: "Some users"
});
});

Node.js Express rendering any *.jade

I have a test node.js server running the following code:
var app = require('express')();
app.set('views', __dirname + '/public');
app.set('view engine', 'jade');
app.get('/', function(req, res) {
res.render('index.jade', {name: "Test data."});
});
app.listen(3000);
This code works find. I'm wondering what the best practices are for choosing a .jade file based upon the url without hard-coding it, kind of like you might for html files using express.static. Of course, I don't want there to be a direct path correlation either (instead assigning different routes to different directories or groups of directories.) There doesn't seem to be a whole lot of solid information on the subject. Anything would be helpful. Thanks.
with utilization of splats you could do something like this:
var app = require('express')();
app.set('view engine', 'jade');
// /foo/Sam/path/to/view.jade yield a rendering of 'path/to/view.jade' with name: 'Sam'
app.get('/foo/:name/*.*', function(req, res) {
res.render(req.params.join('.'), {name: req.params.name});
});
app.listen(3000);

Express 3 - Serving static scripts/styles - Error: Failes to load resource (404)

I am new to node and server-side development in general and started having a look at it today so mind my question. I have looked for suiting answers in previous post, yet somehow every suggested solution was criticized by many users.
I can't serve static scripts/styles due to the following error:
Failed to load resource: the server responded with a status of 404 (Not Found)
I am using express 3.1.0.
Here is my code:
app.js
var express = require('express');
var app = express();
var routes = require('./routes');
app.configure(function () {
app.set('view engine', 'jade');
app.use(express.static(__dirname + '/public'));
});
app.get('/', routes.home);
app.get('/about', routes.about);
app.get('/blog', routes.blog);
app.get('/faq', routes.faq);
app.get('/terms', routes.terms);
app.get('/privacy', routes.privacy);
app.get('/jobs', routes.jobs);
app.get('/press', routes.press);
app.listen(8080);
index.js (routes)
exports.home = function(req, res){
res.render('home', { title: "Home"});
};
exports.about = function(req, res){
res.render('about', { title: "About" });
};
etc...
layout.jade
doctype 5
html
head
title= title
link(rel='stylesheet', href='public/styles/bootstrap.css')
body
block content
br
a(href='../') Home
br
a(href='../about') About
br
etc...
home.jade
extends layout
block content
p Home
When you setup server middlewere it looks for requests at the root unless specified otherwise if you are looking for a stylesheet in "public/styles" you request it at just "/styles"
to make the middlewere answer to requests to /public change it to
app.use('/public', express.static(__dirname + '/public'));
I tried using
app.use('/public', express.static(__dirname + '/public'));
instead of
app.use(express.static(__dirname + '/public'));
and it worked.
However according to the first answer in this post: express.js not serving my image it is not considered good. I can't understand why? And what else would be a better solution?

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');
});
};

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.
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.
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'));
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");
});
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.
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
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');
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:
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");
});
use this code to solve the issue
app.get('/', function(req, res){
res.render("index");
});
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.
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.
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);
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.
I had the same issue and could fix it with the solution from dougwilson: from Apr 5, 2017, Github.
I changed the filename from index.js to index.pug
Then used in the '/' route: res.render('index.pug') - instead of res.render('index')
Set environment variable: DEBUG=express:view
Now it works like a charm.
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.
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
app.get("/", (req, res) => {
res.render("home");
});
// the code below brought the error
app.get("/", (req, res) => {
res.render("/");
})
I was facing this error because i mistakenly deleted my error.ejs file and it was being called in app.js file and was not found in views as it was already deleted by me
