I have a folder named awesome test and it contains index.hml ,node modules and server.js .Here is the server.js file and i am getting this error .
//grab express
var express=require('express');
//create an express App
var app=express();
// create an express route for the home page
// http://localhost:8080/
app.get('/', function(req, res) {
res.sendFile(__dirname + 'index.html');
});
// start the server on port 8080
app.listen(8080);
// send a message
console.log('Server has started!');
Here's where the error is:
res.sendFile(__dirname + 'index.html');
It should be:
res.sendFile(__dirname + '/index.html');
The reason for this is because the index.html is being added upon the directory, which doesn't end with a / by default. You need to add it yourself as shown above.
Hope this helps!
Edit: I tried Node.js before. I think it would be best if you added a "public" folder, with the .js file being above everything. Here's an example:
This was my code for my first Node.js server, as a reference:
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const express = require('express');
const app = new express();
app.use(express.static(__dirname + '/public'));
app.listen(3000, () => console.log("Example app listening on port 3000!"))
console.log("http://"+hostname+":"+port)
Note: To use express as shown above, you'll have to open a command line, and type in the following (assuming you have node.js installed correctly):
npm install -g express
Also, to make sure you installed both node.js, do the following:
Node: node -v
Hope everything helps! ^_^

I want to serve index.html and /media subdirectory as static files. The index file should be served both at /index.html and / URLs.
I have
web_server.use("/media", express.static(__dirname + '/media'));
web_server.use("/", express.static(__dirname));
but the second line apparently serves the entire __dirname, including all files in it (not just index.html and media), which I don't want.
I also tried
web_server.use("/", express.static(__dirname + '/index.html'));
but accessing the base URL / then leads to a request to web_server/index.html/index.html (double index.html component), which of course fails.
Any ideas?
By the way, I could find absolutely no documentation in Express on this topic (static() + its params)... frustrating. A doc link is also welcome.
If you have this setup
/app
/public/index.html
/media
Then this should get what you wanted
var express = require('express');
//var server = express.createServer();
// express.createServer() is deprecated.
var server = express(); // better instead
server.configure(function(){
server.use('/media', express.static(__dirname + '/media'));
server.use(express.static(__dirname + '/public'));
});
server.listen(3000);
The trick is leaving this line as last fallback
server.use(express.static(__dirname + '/public'));
As for documentation, since Express uses connect middleware, I found it easier to just look at the connect source code directly.
For example this line shows that index.html is supported
https://github.com/senchalabs/connect/blob/2.3.3/lib/middleware/static.js#L140
In the newest version of express the "createServer" is deprecated. This example works for me:
var express = require('express');
var app = express();
var path = require('path');
//app.use(express.static(__dirname)); // Current directory is root
app.use(express.static(path.join(__dirname, 'public'))); // "public" off of current is root
app.listen(80);
console.log('Listening on port 80');
express.static() expects the first parameter to be a path of a directory, not a filename. I would suggest creating another subdirectory to contain your index.html and use that.
Serving static files in Express documentation, or more detailed serve-static documentation, including the default behavior of serving index.html:
By default this module will send “index.html” files in response to a request on a directory. To disable this set false or to supply a new index pass a string or an array in preferred order.
res.sendFile & express.static both will work for this
var express = require('express');
var app = express();
var path = require('path');
var public = path.join(__dirname, 'public');
// viewed at http://localhost:8080
app.get('/', function(req, res) {
res.sendFile(path.join(public, 'index.html'));
});
app.use('/', express.static(public));
app.listen(8080);
Where public is the folder in which the client side code is
As suggested by #ATOzTOA and clarified by #Vozzie, path.join takes the paths to join as arguments, the + passes a single argument to path.
const path = require('path');
const express = require('express');
const app = new express();
app.use(express.static('/media'));
app.get('/', (req, res) => {
res.sendFile(path.resolve(__dirname, 'media/page/', 'index.html'));
});
app.listen(4000, () => {
console.log('App listening on port 4000')
})
If you have a complicated folder structure, such as
- application
- assets
- images
- profile.jpg
- web
- server
- index.js
If you want to serve assets/images from index.js
app.use('/images', express.static(path.join(__dirname, '..', 'assets', 'images')))
To view from your browser
http://localhost:4000/images/profile.jpg
If you need more clarification comment, I'll elaborate.
use below inside your app.js
app.use(express.static('folderName'));
(folderName is folder which has files) - remember these assets are accessed direct through server path (i.e. http://localhost:3000/abc.png (where as abc.png is inside folderName folder)
npm install serve-index
var express = require('express')
var serveIndex = require('serve-index')
var path = require('path')
var serveStatic = require('serve-static')
var app = express()
var port = process.env.PORT || 3000;
/**for files */
app.use(serveStatic(path.join(__dirname, 'public')));
/**for directory */
app.use('/', express.static('public'), serveIndex('public', {'icons': true}))
// Listen
app.listen(port, function () {
console.log('listening on port:',+ port );
})
I would add something that is on the express docs, and it's sometimes misread in tutorials or others.
app.use(mountpoint, middleware)
mountpoint is a virtual path, it is not in the filesystem (even if it actually exists). The mountpoint for the middleware is the app.js folder.
Now
app.use('/static', express.static('public')`
will send files with path /static/hell/meow/a.js to /public/hell/meow/a.js
This is the error in my case when I provide links to HTML files.
before:
<link rel="stylesheet" href="/public/style.css">
After:
<link rel="stylesheet" href="/style.css">
I just removed the static directory path from the link and the error is gone. This solves my error one thing more don't forget to put this line where you are creating the server.
var path = require('path');
app.use(serveStatic(path.join(__dirname, 'public')));
You can achieve this by just passing the second parameter express.static() method to specify index files in the folder
const express = require('express');
const app = new express();
app.use(express.static('/media'), { index: 'whatever.html' })
I want to serve index.html and /media subdirectory as static files. The index file should be served both at /index.html and / URLs.

web_server.use("/media", express.static(__dirname + '/media'));
web_server.use("/", express.static(__dirname));

I have created a simple Express JS app. and it is working fine in localhost. when I visit localhost:8000 I see static files (index.html, style.css and frontend.js).
I have tried to deploy that app in a server using cPanel. and I have installed Node app and dependencies using package.json successfully. But when I visit the domain I just see a message (Node JS app is working, Node version is 10.24.1).
How to make my app to point and display the static folder (index.html) and run the app?
My app architecture:
server.js
package.json
public/index.html
public/style.css
public/frontend.js
And here is my server.js startup file:
// Setup empty JS object to act as endpoint for all routes
projectData = {};
// Require Express to run server and routes
const express = require('express');
// Start up an instance of app
const app = express();
/* Dependencies */
const bodyParser = require('body-parser');
/* Middleware*/
//Here we are configuring express to use body-parser as middle-ware.
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
// Cors for cross origin allowance
const cors = require('cors');
app.use(cors());
// Initialize the main project folder
app.use(express.static('public'));
// Setup Server
const port = 8000;
const server = app.listen(port, function(){
console.log(`server running on localhost: ${port}`);
});
//POST Route to store data in the app endpoint, projectData object
app.post('/addData', addData);
function addData (req, res){
let data = req.body;
projectData = data;
console.log(projectData);
}
app.get('/getData', getData);
function getData(req, res) {
res.send(projectData);
}
The problem here is that you are not pointing a route to send the HTML file. Otherwise the client would have to point it to the correct path of the file, Like localhost:3000/index.html.
you need to send it from the server using app.get
app.get("/", (req, res) => {
res.sendFile(__dirname + "path to the file");
});
The problem was that I have created the app in a subfolder of my domain.
But when I have created subdomain and reinstalled the app inside it, the app is pointing to static folder successfully.
I am currently working on a project which is a webpage using angular to dynamically change DOM elements. Within the project is a public folder which contains all HTML, CSS, JavaScript and JSON objects. The project must be distributed so I am using node to run from localhost. This is my server.js code:
var express = require('express');
var app = express();
var path = require('path');
app.get('/', function(req,res){
res.sendFile(path.join(__dirname + '/public'));
});
app.listen(8080, function(){
console.log((new Date()) + " Server is listening on port 8080");
});
When I head to localhost:8080 it just says Cannot GET /. Where am I going wrong?
The correct way to serve static files with express is as follows:
//Look for statics first
app.use(express.static(path.join(__dirname, 'public')));
//Return the index for any other GET request
app.get('/*', function (req, res) {
res.sendFile('index.html', {root: path.join(__dirname, 'public')});
});
Edit: on a side note this may be worthwhile to mention that app.get should be the last route declared in node so if you want API endpoints exposed declare them above (before) the final app.get.
You forgot to point to the actual html file you want to display. If you have a index.html in your public directory, just point tot '/public/index.html' . That works (tested it here).
Followed user Muli's answer and all files are now being served correctly. Code here:
var express = require('express');
var app = express();
var path = require('path');
app.use(express.static(path.join(__dirname, 'public')));
app.get('/', function(req,res){
res.sendFile('index.html', {root: path.join(__dirname, './public')})
});
app.listen(8080, function(){
console.log((new Date()) + " Server is listening on port 8080");
});
I've got a weird trouble with my nodeJS app since I refactored it.
The app starts well, API answers correctly but when I try to go to /, I get this error : Error: ENOENT, stat '/views/index.html' in my browser.
I now use this folder tree :
project
front
views
index.html
bower_components
app
node
server.js
And here is the content of my server.js file :
var express = require('express');
var app = express();
var morgan = require('morgan');
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
var server = require('http').Server(app);
var io = require('socket.io')(server);
var fs = require('fs');
var nconf = require('nconf');
app.use(express.static(__dirname + '/../front'));
app.use(express.static(__dirname + '/../node_modules'));
app.use(express.static(__dirname + '/../bower_components'));
app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended': 'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({type: 'application/vnd.api+json'}));
app.use(methodOverride());
server.listen(8081);
(...) // some code to define API routes
app.get('/', function (req, res) {
res.sendfile('/views/index.html');
});
I tried to comment app.use(express.static(__dirname + '/../front')); and to call the view using '/front/views/index.html' but the result is the same.
ENOENT means Error NO ENTry which ultimately means it's not able to find your file.
int ENOENT
No such file or directory. This is a "file doesn't exist"
error for ordinary files that are referenced in contexts where they
are expected to already exist.
Your server is attempting to send a file from the root directory of your machine (/views/index.html). You'll probably need to adjust this to fit your file structure.
app.get('/', function (req, res) {
res.sendfile(__dirname + '/../font/views/index.html');
});
I believe you missed to set your views folder.
app.set('views', 'MY_DIR_PATH');
As #Sean3z suggested, I tried to change my sendfile declaration and got another error (Forbidden, sendStream error).
Finally I managed to make it work by changing my static files definition :
app.use('/front', express.static(__dirname + '/../front'));
And by modifying the sendFile : res.sendfile('front/views/index.html');
Strangely, nodeJS understands (but not me :) ) and call the right file at the right place. I just need to correct my calls in the differents file to be ok.
Thanks for the answers.
