Hangs forever if launched using typer

[traverseda]

import typer
from nicegui import ui

def main(
        port: int = 5123,
    ):

    @ui.page('/')
    def main_page():
        ui.label('Hello NiceGUI!')
        ui.icon('thumb_up')
        ui.markdown('This is **Markdown**.')
        ui.html('This is <strong>HTML</strong>.')
        with ui.row():
            ui.label('CSS').style('color: #888; font-weight: bold')
            ui.label('Tailwind').classes('font-serif')
            ui.label('Quasar').classes('q-ml-xl')
        ui.link('NiceGUI on GitHub', 'https://github.com/zauberzeug/nicegui')

    ui.run(port=5123, dark=None)


if __name__ in {"__main__", "__mp_main__"}:
    #main() #Works
    typer.run(main) #Does not work

No debug output, it just doesn't run.

You need to set reload=False:

import typer
from nicegui import ui

def main(port: int = 5123):
    @ui.page('/')
    def main_page():
        ui.label('Hello NiceGUI!')

    ui.run(port=port, reload=False)

if __name__ in {"__main__", "__mp_main__"}:
    typer.run(main)

This seems to be caused by the fact that the reloader (watchdog package) runs the file twice: https://github.com/zauberzeug/nicegui/wiki/FAQs#why-is-my-code-executed-twice
