Restart the app

Question

Hello,
Today after just 2 and a half days of work, I have finished a web app, which I will show to my colleages.
That's why NiceGUI is impressive.
For small refinement, I have a question.

Is there is way to restart the app after using ui.shutdown?
I want to the user be able to kill a process and work with the app again, if wanted.

Hi @Shahin-rmz, that's great to hear! 😀

There's currently no built-in way to restart a NiceGUI app. But in some of our projects we do something like this:

ui.button('restart app', on_click=lambda: os.utime('main.py'))

This updates the modification time of the main.py file. Assuming you use ui.run(..., restart=True) (the default), this will trigger a restart since main.py seems to have changed.

That's awesome.
I'll try it out.
Thanks.

This approach isn't perfect. For example, if I use asyncio.create_subprocess_exec in my program, I can't set reload=True(#486)
