Setup a localhost Server


X_ITE uses the fetch API to load files and there’s no way around it. However, this means that files loaded using the file:// scheme protocol are subject to the same origin policy and are treated as cross-origin requests (CORS), and cross-origin requests are only supported for protocol schemes: https, http and data. This means that X_ITE cannot access these files.

To work around this problem, you will need to set up a localhost server, then you will be able to access your local files at the web address http://localhost/…

Using a Browser Extension

You can use this browser extension for Chrome and Edge to create a web server and serve your local files via HTTP. Very easy to use.

Using an Application

There are various applications available online for setting up a localhost server. Among them, I would like to highlight here some options:

MacOS users have the options to utilize the Personal Web Server (for Intel-based Macs) or the Simple Web Server (for Apple Silicon-based Macs). These servers facilitate file serving via a web server and boast user-friendly interfaces. Alternatively, users can employ the provided Node or Python script below in conjunction with Automator for additional flexibility and customization.

Another notable application is XAMPP, renowned for its versatility across multiple operating systems and widespread popularity among users. It provides a comprehensive suite of web development tools, making it a favored choice for many developers and enthusiasts alike.

Using Node

The npm http-server is a straightforward yet powerful tool for serving static resources over HTTP. It’s a command-line program that allows quick and easy access to local file directories via a local web server. With npm http-server, developers can swiftly set up a local development environment to test web applications or host static websites. Thanks to its user-friendly interface and configuration options, npm http-server is a popular choice for developers seeking a fast and uncomplicated way to serve local files over the HTTP protocol.

Follow the instructions on their website to get it up and running.

Using Python

If you have Python installed, then it is quite easy to start a localhost server.

Just open a Terminal and go to the directory you want to make available.

$ # Let's make the Desktop directory available.
$ cd Desktop

Type in the following command to start the server.

$ python3 -m http.server 80

By default, this will run the contents of the directory on a local web server, on port 80. You can go to this server by going to the URL http://localhost in your web browser. Here you’ll see the contents of the directory listed — click the HTML file you want to run.

Tip: If you already have something running on port 80, you can choose another port by running the server command followed by an alternative port number, e.g. python3 -m http.server 7800. You can then access your content at http://localhost:7800.
