Oculus Go wireless connect to PC web server

I assume the website localhost:3000 is on a desktop PC and so knowing the PC's ip address or device name is necessary.
If the localcalhost:3000 is on Oculus Go then the Go IP must be used by the PC.
I am not sure which is the correct solution.

Localhost is a specialized address specifically assigned to loop back locally so only the same PC can use that address.

For desired Oculus Go to see your desktop PC website you will need to know the PC's name and/or IP address usually assigned by LAN router.
The Oculus Go MUST be on the same LAN address space as the PC.

For example,
If PC is MyDesktop.home then use http://MyDesktop.home:3000 or if MyDesktop is assigned 192.168.1.23 then use 192.168.1.23:3000

Alternatively if Oculus Go is to be used outside the LAN then things get complicated beyond this simple explanation.
If viewed from world wide web is desired then port forward on internet provider router from port (ie with subdomain pointing to IP WAN address such that mydesktop.mydomain.com:8080)  points to LAN port MyDesktop.home port 3000 

Thank you CoolGames it works now. I used nodejs http-server and is giving me the full path with ip address, now it works great. Thx again.

I just started to get Termux with Node.js running so eventually will port as install-able like you seem to have done.
