adding where port is at in the source code for port change if needed

[MathMan05]

Please just set the env

[ssfdre38]

Multiple applications require port 8080 this way if somebody wants to change the port without having to change the environmental settings every single time that they are trying to launch the application or test run, this way they can without having to set it every single time

Consider: systemd can do this for you anyways, just add this to your service file:

Environment=PORT=8081

[ssfdre38]

i know it can be done this way as well but for some people like me, we are working on customize it and changing it that way helps to just run the client without having to add it to the startup or an env.

Then that's... on you?
Just add the env var and forget about it, it's a single line in your systemd service lol - the docs dont cover modifying the source code of documented applications for a reason. You're just adding more maintenance overhead to your fork.
