FAQ

My users automatically get directed to localhost when the front end is used

To change the destination URL you must change the URL in configuration.json to your domain / ip

How do I change the ports of the front end and backend?

To change the ports enter the configuration.json and change the backend/front end ports to your desire, then enter backend.js and change the backend port.

Am I allowed to edit the code?

Yes, you are allowed to edit the code as much as you want, but no support will be given.

Am I allowed to reupload the code?

Yes, you are allowed to but please fork the original repository.

DISCLAIMER!!

I am not responsible for anything that goes wrong running this code, running it port forwarded may cause security issues and vulnerabilities.
