How can I make the following server.js code work for .html files instead on .ejs in Node JS. Thanks!
var express = require('express');
var app = express();
// set the port of our application
// process.env.PORT lets the port be set by Heroku
var port = process.env.PORT || 8080;
// set the view engine to ejs
app.set('view engine', 'ejs');
// make express look in the public directory for assets (css/js/img)
app.use(express.static(__dirname + '/public'));
// set the home page route
app.get('/', function(req, res) {
// ejs render automatically looks in the views folder
res.render('index');
});
app.listen(port, function() {
console.log('Our app is running on http://localhost:' + port);
});
You should be able to just remove these lines:
// set the view engine to ejs
app.set('view engine', 'ejs');
// set the home page route
app.get('/', function(req, res) {
// ejs render automatically looks in the views folder
res.render('index');
});
and add your .html files to public/.
Testing this with this code
var express = require('express');
var app = express();
// set the port of our application
// process.env.PORT lets the port be set by Heroku
var port = process.env.PORT || 8080;
// make express look in the public directory for assets (css/js/img)
app.use(express.static(__dirname + '/public'));
app.listen(port, function() {
console.log('Our app is running on http://localhost:' + port);
});
and this directory structure
├── package.json
├── public
│ └── index.html
└── server.js
Works fine for me.

I'm having a problem connecting an express server with a gulp serve/r task. In order to send my views to the DOM, I need express to do that. I'd like my server to run as a gulp task. The server runs, however when I try to access my local url it runs an error in browser:
Error: Failed to lookup view "index" in views directory "C:\Users\User Name\Documents\project\src\scripts"
My app.js
var http = require('http');
var express = require('express');
var exphbs = require('express-handlebars');
var path = require('path');
var hbs = exphbs.create({ /* config */ });
var app = express();
//environment variable
var port = process.env.PORT || 8000;
// static files + template engine
app.engine('handlebars', hbs.engine);
app.set('view engine', 'handlebars');
app.set('views', path.join(__dirname, '../scripts'));
app.use('/public', express.static(__dirname + '/public'));
//http request method get json list
app.get('/', function(req, res) {
res.render('index');
});
app.listen(port);
My file structure looks like this:
project
|-- src
| |-- css
| |-- scripts
| |-- app.js
| |-- index.html
What am I missing?
You should change this:
app.set('views', path.join(__dirname, '../scripts'));
to this:
app.set('views', path.join(__dirname, '..'));
This is because the index.html file resides in the src directory which is a parent of the scripts directory from which the script is executed.
My project structure looks like this:
project
assets/images/
css/application.css
js/application.js
font
node_modules
index.html
server.js
package.json
My goal is to be able to run 'node server.js" in the project folder and have it serve on port 80. Going to localhost:80 or w.e would render the index.html along with its css/assets/js.
I've tried with connect, express and http but no luck...new to node.
Thanks!
First of all, change your structure:
project
assets/images/
assets/css/application.css
assets/js/application.js
assets/font
node_modules
views/index.html
server.js
package.json
First require some packages:
var express = require('express'),
app = express(),
path = require('path');
Them run in the terminal window:
npm install express
Them set up the configurations:
app.set('views', path.join(__dirname, 'views')); // This is to serve static files like html in the views folder
app.set('view engine', html); // your engine, you can use html, jade, ejs, vash, etc
app.set('port', process.env.PORT || 80); // set up the port to be production or 80.
app.set('env', process.env.NODE_ENV || 'development');
app.use(express.static(path.join(__dirname, 'assets'))); // // This is to serve static files like .css and .js, images, fonts in the assets folder
Them create your routes:
app.get('/', function(req, res) {
res.send('Hello word');
});
app.get('/something', function(req, res) {
res.send('Hei, this is something!!!');
});
If you want render the index, inside the views folder:
app.get('/index', function(req, res) {
res.render('index');
});
And finally:
app.listen(app.get('port'), function(req, res) {
console.log('Server listening at ' + app.get('port')');
});
Them access localhost:80/index
Put your assets and subdirs under ./public, then from top dir, add app.js:
var express = require('express');
var app = new express();
app.use(express.static(__dirname + '/public'));
app.listen(80, function () {
console.log('Server running...');
});
I am completely new to node and trying to work with webRTC application.
I have installed node,express and socket.io in my project, However when I try to run app.js I get error. I am unable to debug because I am not experienced enough to spot the error.
The following is the code in app.js
var express = require('express')
, routes = require('./routes')
, http = require('http');
var app = express();
var server = app.listen(3000);
var io = require('socket.io').listen(server); // this tells socket.io to use our express server
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.static(__dirname + '/public'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
});
app.configure('development', function(){
app.use(express.errorHandler());
});
app.get('/', routes.index);
console.log("Express server listening on port 3000");
When I write the command node app.js it shows the following error.
I have setup exprees in my project.
The file structure inside webRTC directory is as follows
Here is the link to webpage that accompanies step by step to setup node,npm express and socket.io inside a peoject . I have followed every step properly but the part where it says to run app.js after downloading socket.io it shows error.

I am trying to create a SPA app, but when i start my application it does an infinte loop leading to a crash. I am using ExpressJS 4.3.0
App architecture:
public
--partials
----index.jade
server.js
My express code:
var app = express();
var port = process.env.PORT || 8080;
app.set('views', __dirname + '/public');
app.set('view engine', 'jade');
app.use(express.static(__dirname + '/public'));
app.get('*', function (req, res) {
res.render('partials/index');
});
app.get('/', function (req, res) {
res.render('partials/index');
});
app.get('/partials/:name', function (req, res) {
res.render('/partials/' + req.params.name);
});
app.listen(port);
console.log('Server is running on port: ' + port);
If i use
res.render('/partials/index');
i recieve a message:
Error: Failed to lookup view "/partials/index" in views directory
Its because of view lookup function in express view lookup
if (!utils.isAbsolute(path)) path = join(this.root, path);
which makes it assume '/partial/index' is already an absolute path and didnt prefix with root path.
Also move the
app.get('*', function (req, res) {
res.render('partials/index');
});
to end else it will always serve the index view.
It looks like you shouldn't have a preceding / in your view path in render(). Just use 'partials/' + req.params.name.
On a related note, are you sure you want your actual view files to be public? Usually they are stored outside of the public static directory (e.g. ./public contains static assets and ./partials contains views). Also that way you don't have to keep prefixing view paths with partials/.
I want to use connect's vhost functionality to deploy several express.js apps to my dev vps. Here is my server.js file that is supposed to send requests to the appropriate place:
var express = require('express')
var quotes = require('quote-of-the-day/lib/app.js');
var server = express();
server.use(express.vhost('inspiringquoteoftheday.com',quotes));
server.listen(80);
Running node server.js throws this error:
Error: Cannot find module 'quote-of-the-day/lib/app.js'
Even though I can cd into app.js straight from the directory where server.js is located.
Here is the lib/app.js file in which I export my express app (I think)
// Generated by CoffeeScript 1.3.3
(function() {
var app, express, pub;
express = require('express');
module.exports = app = express();
pub = __dirname + '/public';
app.use(express["static"](pub));
app.use(express.errorHandler());
app.use(app.router);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.get('/', function(req, res) {
return res.render('home');
});
}).call(this);
Assuming a directory structure that looks something like this:
|-. quote-of-the-day
|-- server.js <-- the file you list in your question
|-. lib
|-- app.js
Then you should require your app.js with
require('./lib/app');
Might be helpful to use the __dirname global variable here.
it provides 'the name of the directory that the currently executing script resides in.'
thus you could do:
var otherApp = require(__dirname + 'quote-of-the-day/lib/app.js')
