Delivering static content in Express without specifying an IP address

In my template files, I consistently use the following code snippet:

<link href="http://localhost:3000/css/bootstrap.min.css" rel="stylesheet">

Each time I launch the website, I need to update the IP address from http://localhost:3000 to the web server's IP. With numerous template files across the site, this becomes a tedious task. To avoid this, I have developed scripts that can automatically replace the IP in the template files whenever needed.

I would prefer to maintain the format like this:

<link href="css/bootstrap.min.css" rel="stylesheet">

This way, it is not tied to a specific origin. Ideally, there should be middleware in Express that can use the server's current location to serve the files.

Currently, in my server.js file, I am using the following code:

app.use(express.static(path.join(__dirname ,'/v1/public/')));

It works well when I specify the host in the template files. However, I have not come across any readily available resources that offer a simple solution to achieve what I'm looking for.

Answer №1

Instead of embedding the full URL directly in the header template file, a more flexible approach would be to pass it as a variable. This way, you can dynamically construct the URL at the application level using code similar to this:

var baseUrl = req.protocol + '://' + req.get('host');

Then, simply pass baseUrl to your header template and append paths as needed during runtime.

Answer №2

Consider using:

href="http://example.com/css/bootstrap.min.css" rel="stylesheet"

or a relative path:

href="./css/bootstrap.min.css" rel="stylesheet"

The static folder you choose will determine where the static resources are served from.
