Struggling to load app.css, main.js, and other files while using an Express server

Struggling to load app.css, main.js, and other files while using an Express server

I'm struggling with my code setup. Essentially, I have the following piece of code:

var express = require('express');
var app = express();
var server = require('http').Server(app);

app.get('/', function(req,res){
 res.sendfile(__dirname + '/index.html');
});

server.listen(3000);

The issue is that only my index.html page is loading properly, while encountering a GET error for all my other files. Even when I try to load the index.html at localhost:3000, my main.js and app.css files are not found according to the console errors. I've attempted to include the other files as sources in the html file too, but they still won't load. It seems like this problem occurs because I am sending just one html file to the server. How can I adjust this set up to ensure that all necessary files are successfully sent to the server?

When handling a get request, simply using:

res.sendfile(__dirname + '/index.html');

may not serve all your static files. Only the index.html file will be served, so your CSS and JavaScript files may not be found by the server, even if they are linked in your HTML.

To ensure all your static files are accessible, you should utilize the express static middleware, which is the only included middleware in Express version 4.

If your static files are located in the same directory as your server.js file, include the following line of code:

app.use(express.static('.'));

This will serve up all local static files and make them available on your server.

No specified route has been provided for accessing the linked files.

To handle this, consider using the express.static middleware found at http://expressjs.com/api.html#express.static

Extracted from the documentation:

Here are some examples demonstrating how to utilize the express.static middleware within an Express application.

To serve static content for the app located in the "public" directory of your application directory, you can use the following:

// GET /style.css etc
app.use(express.static(__dirname + '/public'));

If you want to mount the middleware at "/static" and only serve static content when the request path is prefixed with "/static", implement the following:

// GET /static/style.css etc.
app.use('/static', express.static(__dirname + '/public'));

To disable logging for static content requests, load the logger middleware after the static middleware as shown below:

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

In cases where you need to serve static files from multiple directories but prioritize "./public" over others, use the following setup:

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