I am new to node and running a .js script using node command prompt window, see following

I’m trying to build my current project it in a way so my friends can create servers on one network so we can connect to each other (LAN communication, pretty much). The only problem is when I run my program in two terminal windows, my second run fails and throws errors at me because ports are already taken, which is logical.

A Node program of mine that worked fine in Node v21 now immediately crashes with a syntax error in Node v22. The line that triggers the error looks like this:

I am working with Node.js servers. When I log on to the server, the code,

will run and I will only get the “What ever text you choose” no matter what path I type. I know you can “write” a file so every time you log on to the server, it will give you that page. The problem I am having is that the server will only give me the one file. How can I request a different file based on the URL?

Given this code:
