How to run different UIs from different files?

[clueple]

I had 2 Python files in my local drive G:/app folder - A.py & B.py

I could run A.py without any problem.
But when I tried running B.py in command prompt (under a virtual environment),
it showed A.py 's UI.

Is there any way to run different .py like it did in Flet?
(e.g. in CMD)
(your_env) Flet A.py ---> shows A.py 's UI
(your_env) Flet B.py ---> shows B.py's UI

I couldn't figure that out after reading the fastapi and uvicorn's documentation.

Many thanks.

I think you need to use different ports. NiceGUI runs with port 8080 by default. If A is still running, B should complain about the port 8080 still being in use. But the browser opens nonetheless, showing A's UI.

Just use something like ui.run(port=8081) in B and both UIs should work independently of each other.

Thanks @falkoschindler, let me think about how to stop the port (after pressing 'x' to close 'A.py' and let the port listen to 'B.py'.

Thanks for your info.

I'm not sure if this (see original link from stackoverflow below) is correct.
What it does:

1. killing the port:8080 when it is in use by whatever program
2. launch the program (e.g. run your whatever_nicegui_app.py) with default to port:8080

Let me try if it can enable 'running different nicegui_app.py files without needing to set the port other than 8080'.
Currently, even when you close nicegui_app1.py,
when you run nicegui_app2.py, you will still see the ui of nicegui_app1.py in page 127.0.0:8080
